Title: "SKS" Fenders??
Post by: SilasTarr on July 06, 2011, 11:25:06 pm
Greetings, my friends.

While researching and purchasing my gear for my first tour, I've come across a topic that's got me rather confused!

Everyone recommends (and I agree) that getting fenders for your front and rear tires is the way to go.  Beyond that, though, I don't know what to think!  I see a lot of people recommending "SKS" fenders, but I don't know what this means.  Is "SKS" a brand?  A style?  A model?  I've been unable to find anything in these forums or elsewhere online that points me in the right direction.  I figured out that "ATB" fenders are for "All Terrain Bikes," and I've realized that fender "sizes" are talking about the fender width in millimeters (mm), but that's about all I know.

I've got a Surly LHT with 26x1.5" wheels, so what type/brand/size/etc. of fenders would you all recommend for me?

Thanks in advance for your help!

Lots of good fenders out there (Soma has great colors-one  matches my Waterford's blue perfectly). Planet Bike is another good one. The main thing is to get full coverage fenders not the quick-on shorties.

SKS plastic fenders look like shite.  Get some nice aluminum fenders at VO:

http://store.velo-orange.com/index.php/accessories/fenders.html

Fenders should be roughly 10mm bigger than your tires.  The problem with fenders is that things can get jammed between the tire and the fender with catastrophic consequences.  So the more clearance the better.

The first hit on google for "SKS fenders" is the Universal Cyles web page, which shows pictures of all the different models of SKS fenders.  That is followed by links to Peter Whites website and the Rivendell website, both of which sell SKS fenders.  You couldn't find any information on "SKS fenders"? ??

Oh, I didn't say I couldn't find anything about "SKS fenders;" on the contrary, I found SKS fenders everywhere I looked.  What I couldn't find was anything that told me what "SKS" was.  A brand?  Style?  Model?  I originally thought it was a specific type/size of bike fenders since the bike shop that sold me my Surly LHT recommended "SKS fenders" when I asked what kind of fenders would work on my bike.  I think I've now realized that "SKS" is a brand (still no idea what it means, though), and that they make just as many different kinds of fenders as any other company in the business.

Thus, I'm still at a loss for knowing what makes "SKS" fenders unique/special/good to see them recommended so often, and I'm still trying to figure out what size I should be looking for to fit my 26x1.5" wheels.

SKS is a German company:
http://www.sks-germany.com/index.php (http://www.sks-germany.com/index.php)

They market their attachment system:
Quote
Function Secu -clip
The SECU-Clip is the smart problem solution for foreign parts
caught up by the tire, which sometimes lead to the blocking of
the front wheel in the past. In cases like this, the SECU-Clip
releases the stay and prevents possible crashes.

You will see their size recommendations here:
http://www.sks-germany.com/?l=en&a=product&r=mudguards&i=6409800121&CHROMOPLASTICS (http://www.sks-germany.com/?l=en&a=product&r=mudguards&i=6409800121&CHROMOPLASTICS)

It is desirable to have a fair amount of clearance between the outside circumference of the tire and the inside of the fender.  When mud/sand sticks to your tire it can get caught between the tire and the fender and make it hard to pedal.  Although others may disagree, in my experience this has never been dangerous, but it can make pedaling quite difficult!  Now a stick in the spokes is another story, that sounds downright dangerous, but even with SECU-Clip fenders a stick could cause a crash when it hit the fork, chain stays or seat stays.  The clearance is a function of your tire size and your frame, not much you can to about it after you have the frame.

Personally I have always used brands other than SKS.

Yet you were the most helpful in answering just what an "SKS fender" is!  Thanks for providing links to the company's website.  I now feel that I can make an educated decision here.

Would you recommend a different brand of fenders?  Why or why not?

Thanks again!

I have SKS full-coverage fenders on several of my bikes, and have no complaints. They aren't as "sexy" as some of the fenders out there, but who really needs hammered metal fenders made by artisans in Japan, anyway? (Apparently people do, as they sell for premium prices.)

I've also used SKS "clip-on" style fenders in the past, with pretty good resutls, too. They definitely aren't as good as full-coverage fenders, but are much more convenient to use when packing up a bike for traveling, for example (we used them on our S&S tandem, and they make it much easier to fit the tandem in the S&S cases when compared with full fenders. In this case, I'm willing to give up some of the performance of the full-coverage fenders for ease of mounting/unmounting and overall packing size.

Fenders are not that complicated.  A polymer set, front and rears, is on the order of $50, regardless of who makes them.  And as has been implied, you can spend a lot more for aluminum or carbon fiber fenders.  Actually, aluminum fenders aren't too bad as I think they are $100 per set.  

For the record, when I built up my touring bike, I bought a set of Soma Fenders (http://www.somafab.com/eurotripfenders.html (http://www.somafab.com/eurotripfenders.html)).  I bought them because they had a nice fluted look.  They do not appear to have fluted fenders anymore, but they do come in some pretty colors.

Last spring, I bought these fluted aluminum fenders:

in size 50mm (700c) on sale for something like $35, and regularly they are $55.

SilasTarr,

I am in the process of looking for fenders also for the same size tires- 26 inch x 1.5 inch.

The SKS Esge Fenders P55 (55 mm) would fit your tire. 

I have a question of my own for anybody to answer.  A lot of companies make fenders in size 45 mm and a size 60 mm.  Which one would be a better fit for 26 inch x 1.5 inch tires? 8)
Title: Re: "SKS" Fenders??
Post by: happyriding on July 13, 2011, 12:54:38 am
1.5 in = 38mm

38mm + 10mm for clearance = 48mm minimum

However, often times tires are smaller than their listed size, so to get a more accurate minimum size, you could measure your tire with some metric calipers.

New to the board and I appreciate some of the guidance and experiences posted here.  I'm just getting into the touring style of riding an the posts here helped me out.  I just purchased a set of SKS fenders and I'll let you know how they worked out from a rookie perspective.



Title: Re: "SKS" Fenders??
Post by: ReCycledNE on July 22, 2011, 06:36:20 pm
Okay fenders arrived in mail and just finished installation.  Now that they are on, I love the looks and style.  I have a black bike and these matching fenders almost blend in so well that you don't notice them.  I installed the P-45s and I use both 700cx28s and 32s for tires.  They also seemed to be very solid and high quality, once installed.  Before I got them on, I had some concern...

Now the bad:  The instructions were practically useless.  There was no parts list and SKS includes several "extra" nuts and bolts to accommodate various frame types and installation methods.  This is a nice thing but I still wish they provided a parts list and indicated this fact on the instructions.  Before installing, make sure you have a Drimal, bench grinder, or some other easy way to cut and trim pieces.  I had to take off between .5 and .75 of an inch from the mounting stays because they were too long.  A Drimal worked perfectly and I used a bench grinder to re-smooth the ends.

Lastly, There are lots of little parts to put together and line up in order to mount the fenders on the ends of the stays.  This was a royal P in the A, especially after getting them together, mounting them on the bike and realizing the stays were too long and needed to be cut down...build, tear apart, repeat... >:(

At the end of the day, patience overcame a fairly difficult installation and adjusting process but now that I'm finished, it was worth it.  Hope this is helpful to someone out there.

I have SKS brand fenders on my touring bike. I like them because they enable me to put the widest possible fender that would fit, incase I wanted to go with a wider tire.  I also have a bike or two that use Planet Bike Fenders and they are a little less expensive and work well.
Title: Re: "SKS" Fenders??
Post by: SilasTarr on August 01, 2011, 12:33:06 am
Hello again, everyone.

Well, I ended up purchasing some SKS fenders, but I may have made a blunder so I'm coming to you guys for some help.

Following the advice on the Peter White Cycles page on fenders (http://www.peterwhitecycles.com/fenders.asp), I purchased a set of SKS P50 fenders for my 26x1.5" wheels.  However, upon receiving the fenders in the mail, the noticed a list of all the SKS "P" models on the packaging that said P50 is for 28" wheels, and I was reminded that a P55 model exists that fits 26" wheels.  I guess all the model numbers got jumbled in my head when I made my purchase through Amazon.

I decided to go ahead and attempt mounting the fenders, but the problem I quickly ran into is the the stays hold the fender a few inches too far away from the wheel.  I considered calling it quits there, but then I was intrigued by the final sentence in the mounting instructions.  After instructing me to attach, adjust, and fasten everything in place, the directions say, "The protruding stay can either be cut off or fitted with an endcap."  Now, I realize the instructions were translated from German to English, so something may have been lost in translation here (like elsewhere in the instructions), but this seems to be suggesting that I can actually cut short the metal stays if needed.

What advice can you all give me?  Do you think shortening the fender stays by cutting them can make these fenders fit?  Is there another, better way to fit SKS P50 fenders to my 26" wheels?  Or, should I simply try to return my purchase and exchange for some P55's?

The curvature doesn't look like it's too far off, but your mounting is squirrely.

The first thing you need to do is rotate those fenders so they pass below the head tube.  There should be a bracket in your package that wraps around the fender, and mounts to a hole in the top of the fork where center pull brakes would mount, if they were being used.

Then loosen all the stay mounts, and slide them out until the fender is about a half inch from the tire.  Take off the plastic caps.  Tighten the stay mounts (this is a good place to use thread lock).  You'll want to cut the fender stays short, just a bit past the nut.  You may be able to do this with some sort of lineman's pliers, or just use a Dremel.  I'd suggest you take a file or sandpaper and round the edge of the stay, because the plastic caps won't really stay on.  Then put the caps back on.

The "mounting" of the front fender shown in the picture I provided simply demonstrates how far away the fender is from the wheel even at its closest setting (without having cut the stays).  Because of this distance, the fender won't fit under the head tube/fork at all, which is why I wasn't able to mount it correctly.

I understand the process of fitting the fender in place and then fine tuning its distance from the wheel; my problem is that I can't fit it in place at all!  So again, is it possible (and a good idea) to cut the metal stays short so that the fender can fit under the head tube, or is this an indication that the P50 fenders won't fit on my 26" wheel?
Title: Re: "SKS" Fenders??
Post by: tsteven4 on August 01, 2011, 06:47:23 pm
My advice would be to see how the fender fits, in the intended position with the front under the head tube i.e. with the fork crown fitting against the rear of the fork, without the stays attached at all.  If it looks good proceed.

Traditionally the "endcap" #1 was much simpler and really was a just a cap that slid on the end of the stay after you cut it to length. The disadvantage of the traditional cap is that it could get knocked off and lost.  An advantage was that you could slide the fender towards the wheel without any limitation from the endcap (although you had to cut down the stays anyway so they don't hit things like your leg and hurt you).  You might be able to assemble the fender without the endcaps at all before cutting the stays and make sure you are happy with the fit.  Make sure you route the stay outside of the bridge on the fender.  Then mark, cut and reassemble with the end caps.  I don't have any experience with these particular end caps, I am just looking at the instructions. 

On every pair of fenders I have ever mounted I had to cut all the stays to length.  This is normal.  I don't find the sentence you mentioned in the instructions here: http://www.sks-germany.com/download/6409800121/all/Chromoplastics-Installation.pdf

Alternatively, just take it to your LBS.  After nearly 40 years of working on my own bike I take this route more and more!  They know exactly what they are doing, they can do it very quickly without any mis-steps, and they have the touch (or a torque wrench for more complicated things) to get it all tightened up right.  I am lucky enough to live near http://www.vecchios.com/ (http://www.vecchios.com/)

Post by: SilasTarr on August 01, 2011, 09:47:12 pm
Thanks for the insight, tsteven4.  I didn't know that having to cut the fender stays is typical, so now I think I can proceed looking into the best route to take.

By the way, the sentence I quoted from the SKS instructions is indeed found in the online instructions you linked to.  It's the very last sentence on the second page.

Thanks again!

I don't understand why the fenders can't come in further.  Back when I bought my last pair, it was possible to loosen the nuts on each stay, slide the mounting bracket down the stay, bringing the fender in closer to the hub, and sliding the mounts around the fender to wherever they needed to be.  Get everything arranged just so, tighten the nuts on the brackets, cut the stay, and you're done.  Has SKS changed their mounting so this isn't possible?
Title: Re: "SKS" Fenders??
Post by: SilasTarr on August 02, 2011, 11:43:32 pm
I think it will be possible, I'll just have to keep the "endcaps" off until the stays are cut.  The instructions had me initially insert the stays into the endcaps, and that's what prevented me from bringing the fender in closer to the hub.

By the way, in case I decide to cut the stays myself, any suggestions on exactly how to do this or what tools to use?

If you've got a Dremel, use a cutoff wheel.  Otherwise, a hacksaw or bolt cutters should work.

The fender is NOT in the closest position but the furthest from the wheel in the photo. Loosen those nuts and push the fender down the stays. The length of the stays has no bearing on how close to the wheel the fender is. 
Title: Re: "SKS" Fenders??
Post by: SilasTarr on August 04, 2011, 05:34:13 pm
The length of the stays has no bearing on how close to the wheel the fender is.

It does if you have the plastic endcaps on like the SKS instructions tell you to do first!  But when those are off, you're right, I can slide the fender as close to the wheel as needed, from which point I marked the stays and subsequently cut them short.  I ended up cutting off about 45 mm from the front stays and 25 mm for the back ones.

Thanks to everyone for helping figure it all out!  They look great; I can't wait to give them a try on a rainy day.

Your fenders should be much closer to your tires.  If you look at your bike from the side, you shouldn't be able to see any daylight between the top of the tire and the fender.  In other words, the sides of the fenders should overlap the top of the tire.  Be careful about mounting the fenders too close to the tire, though.  You should have 10mm of clearance between the top of the tire and the fender.
Title: Re: "SKS" Fenders??
Post by: tsteven4 on August 06, 2011, 12:11:42 pm
I agree with happyriding that you have an extreme amount of clearance.  But I don't necessarily agree that you shouldn't be able to see daylight, or that you have too much clearance.  Here is what I would consider to decide:

More clearance is good for adverse conditions when mud/sand/dirt sticks to the tires and rubs between the tire and fender.  The amount of mud that can stick to a tire is about limitless, but at some point it doesn't matter because it is hitting other things like the chain stays.  More clearance is also good if you decide to throw on some bigger tires, for example some knobbies for off road touring or just some really fat ones for crappy roads like you might find in Russia.

In my experience there are two problems brought about by too much clearance.  The first is an overlap between your toe and the fender.  This usually happens on smaller frames with 700c wheels, but it might be an issue with your current setup.  At very low speeds you can turn the handlebars enough that the tire passes by your toe.  The fender may hit your toe.  This is not desirable, but with an experienced rider an overlap isn't the end of the world either.  The second problem is an issue with shipping.  We usually ship the bikes with the rear fender on, and it makes the bike longer which can be an issue with the box.  We loosen the stays and slide the fender towards the tire to mitigate this.  With the style of endcaps you have you might be limited in how much you can do this.  Also, with the rear fender far from the tire it can get caught on the box when you put it in and you can break the fender.  While I have never experienced it a third problem could be interference between the fender and the straddle cable on the brakes.  Note that changing the length of the straddle cable will change the mechanical advantage of the brakes, so it isn't necessarily something you want to do to create more clearance.

Time to get that thing on the road!  Happy Trails.

I too, have a Surly LHT 26er.

I have the SKS full fenders installed and love them. THEY ARE NOT PLASTIC! as several posters have contended. They are metal coated with plastic and very heavy duty.

Although I have yet to need this feature I love the quick release in case of something jamming between the tire and fender.
Title: Re: "SKS" Fenders??
Post by: popeyespal on August 07, 2011, 10:13:56 am
BTW....my fenders were installed at my LBS, (Harris Cyclery...home of the great Sheldon Brown), and they have about the same clearance as yours.

I agree that the only issue with fender placement would be "toe strike" during turns and if you are not having that problem then ride on my friend.

Post by: Tourista829 on August 07, 2011, 12:35:48 pm
You made a good save. Closer is definately better but they will be easier to clean out the gunk that may accumulate after you ride through any mud. I am disappointed with Peter White, he should know better and refund your money.

The closer a fender is to the tire, the less spray will be directed at the rider.  Unless the op is touring off road, the fenders would be more effective if they were closer to the tire.  Some people who switch between fat tires and skinny tires will mount their fenders to fit the fat tires, and therefore when they have the skinny tires on, there will be more clearance than ideal.  Here are pictures of a bunch of bikes with fenders, so you can see how other people are mounting fenders:

Post by: SilasTarr on August 07, 2011, 07:17:57 pm
Thanks for the additional feedback, everyone.  I'll definitely look into bringing in the fenders closer to my tires, as even I thought it seemed like a lot of clearance.  That's about the closest I could get them with how much (or how little) of the stays I cut off, though.

Luckily, I have no plans on boxing up my bike for shipping any time soon, as I'll be heading out from my home when I begin my multi-month tour near the end of this September.  I mostly plan to stay on roads, but I imagine I may encounter some dirt paths or gravel roads, so I surmise I'll want to keep a little extra fender clearance, though perhaps not as much as I have now.  I'll also look into the possibility of my toe hitting the fenders from different positions; thanks for the tip, tsteven4!

Also, just to note...
I am disappointed with Peter White, he should know better and refund your money.
While I used the information I found on Peter White's site to choose which SKS model to purchase, I ended up buying my fenders though Amazon.  So, I guess just use this experience as a heads-up to others that Peter White's information on SKS fenders isn't entirely accurate.


Lastly, thanks @happyriding for the link to the "bikes with fenders" picture collection.  I can see there's a lot of variation in clearance positioning, so I'll just have to do a little more tinkering to find out what works best for me!

I imagine if you find muddy enough conditions to clog your fenders, you won't be able to stay upright anyway unless you are using wide, knobby tires.  Setting up a bike to handle both road conditions and muddy off road conditions is probably going to provide poor riding in all conditions.

The main problem with getting fenders set up properly is figuring out how to extend the fenders to the right height above the tires.




Title: Re: "SKS" Fenders??
Post by: Pat Lamb on August 08, 2011, 09:02:46 am
I agree the clearance looks excessive, but I'm not sure it matters.  The main thing is that the width of the fender catches the overwhelming majority of spray off the wheel.  If the fender is too far out, and not much wider than the tire, then you may have lots of spray coming out that the fender could, and should, catch.  We almost need a 3-D view to see what's going on, but you'll figure it out shortly after the first time you get caught in the rain.

Here is a pic of my LHT and SKS fenders exactly as they were installed by my LBS.

I have ridden in some pretty heavy rain this year with absolutely no issues whatsoever.  No toe overlap, (I am 6'2" and the bike is a 60cm). No excess spray.

I called Harris Cyclery to see if possibly my fenders had been installed incorrectly and I explained why I was asking by quoting some of the posts in this thread. They laughed and said they have seen FAR MORE problems with fenders mounted too close than too far. I ask why and was told that having the fenders too close can cause small objects that would otherwise be picked up by the tire and slung off to actually wedge/contact both the fender and tire causing cuts and possible flats.

Works for me and that is all that matters.

For what it's worth when I went to use a set of fenders I had off a 26" wheel on my 700c bike I found the stays were too short. I made some "fender stay extenders" from aluminum for both the front and back. Lots of miles and no issues.

What I found was they worked nicely as a means to adjust the fender spacing and side to side spacing also. You can see the rear ones in this photo where the stay attaches to the bike.

I called Harris Cyclery to see if possibly my fenders had been installed incorrectly and I explained why I was asking by quoting some of the posts in this thread. They laughed and said they have seen FAR MORE problems with fenders mounted too close than too far.

I would note that it takes more work to install a fender properly.  For instance, on your bike it might have involved finding or making a bracket that extended the fender closer to the wheels.  Sometimes the supplied hardware that comes with a fender is a fixed length, so you don't have any choice where your fender is going to end up.  For most bikes, which have very little clearance between the top of the tire and the fork, you just install the fender as high as possible and hope you have 10mm of clearance for safety.  But if a bike has enough clearance, installing fenders can require a lot of creativity in order to get the fender 8-10mm above the tire.

There is also the issue of liability.  I imagine a bike shop would lean toward installing fenders with too much clearance.

But who knows, maybe a fender that's 10mm from the tire is a death trap.  I've never read any studies about fender safety, and I pretty much just accept what people who have been installing fenders for years say.  They could be wrong.  Jobst Brandt has demonstrated that a lot of things that are taken for granted in the bicycling world have no basis in fact.

Nice fender foo.

For what it's worth when I went to use a set of fenders I had off a 26" wheel on my 700c bike I found the stays were too short. I made some "fender stay extenders" from aluminum for both the front and back. Lots of miles and no issues.

What I found was they worked nicely as a means to adjust the fender spacing and side to side spacing also. You can see the rear ones in this photo where the stay attaches to the bike.

For a road bike those fenders are too far from the tires. If you ride in Germany they will probably give you a ticket :)

(SKS= Scheffer-Klute Sundern) Scheffer-Klute is the company founder's name, Sundern (http://en.wikipedia.org/wiki/Sundern) is the home town of the business. (from the SKS website)

All this discussion has got me thinking I may get my LBS to mount them on my wife's new bike. I've done it myself before and it is a bit of a faff especially cutting the stays to length.

I don't know about your LBS, but I could do it as well and as quickly as REI did a few years back when we bought my daughter's bike and had them install fenders.  It's not like a light or speedometer that they install all the time, so either you or your mechanic will have to sit down and read the instructions, and then interpret the pictograms.

The single best bit of advice I've seen regarding SKS fender installation is to make sure you file the ends of the cut fender mounting rods round.  Greatly reduces the chance to stab yourself (or your wife).

My rear wheel picked up some debris and folded the fender accordion fashion as depicted in the drawing.  SKS fenders are tough.  It just popped out with a slight crease.

My back wheel locked up and it did not do my tire much good either.  IMO- the safety release on the front fenders are really a selling point.  I'm just glad it was my back wheel!

No matter what kind of fenders you get (I have SKS from REI) if you care about your buddy behind you add a proper mud flap to the rear fender. Planet Bike fenders have a little flap dealy that looks like it will prevent you washing your pal behind you with a rooster tail. It is worthless.

SKS Longboards on my Surly 700C LHT.  I like em.  They were ok when I got them but great after riding in the rain.

If you lose a fender stay cover use a Presta valve cover.
