General Discussion / Re: Bike shops near Seatac airport
« on: March 17, 2016, 12:05:14 am »
Riding from SeaTac or Burien Cycles to downtown can be a pain although the light rail would be painless. Send me a PM and I'll take you the Secret Low Traffic Route to Pioneer Square. If you're up for it I'll take you along Alki Beach with its fabulous views of downtown, it's a bit further but nicer riding. After that you're on you're own. Chances are I'll be around because I'm retired. I live about 3 miles from the airport. BTW I highly recommend Burien Cycles. In my experience they are keen competent young guys who charge very reasonable prices.

I found s cheap Chinese Multitool that was junk, the blade wouldn't cut butter etc. I pounded its spike thing into a tree to hold a guy line. Next morning I left it there for anybody who wanted it, I certainly didn't. About 5 miles up the road a pickup pulls up in front of me. "You left you're tool..."

As to just making changes because the machinery is worn out, note that Shimano still makes both square taper and Octalink bottom bracketrs despite the fact that the vast majority of the OEM market has made them obsolete.   
This reminds me of he Bob Newhart skit about General Chariots board meeting. "Do these holes in the chariot sides serve any purpose?" Someone has the temerity to ask. "Yes they serve a purpose: they keep us employed next year" the CEO replies.

Thanks Paddleboy. I suppose they'll go like my old BB with a just perceptible wobble. Interestingly the Hollowtech has fixed what I thought was a problem with the rear derailer. It was jumping gears on the larger cogs, especially when honking. It's stopped doing that now. I believe the wobble in the rings was moving the chain just enough to cause an inadvertent shift. There was I thinking it was the detents on the shifter worn out (one of the very few original components on the bike) Not even Sheldon mentions that as a cause of autoshifting. http://www.sheldonbrown.com/autoshift.html

It's an outrageous lie that square taper bb's are no longer available, even from Shimano. Bikes stores that tell you this are quite literally ripping you off. They should be held to account.
Just Google UN55 (the Shimano bb at the most reasonable quality/price point for touring bikes) and you'll find literally hundreds of offerings.
However I have toured many thousands of kilometers on a Hollowtech bb also, with no issues at all.
It is posible that users who ride a lot in wet, muddy UK conditions would experience more issues, but then they probably have more issues even with square taper bb's.
Good point about the UK conditions. Actually it wasn't the BBs but the square taper cranks the man said were unavailable. Because the originals were so old and beat up I was worried about them breaking so I asked him to put new cranks on as well. Thanks for the reassurance Ron. It seems like I'll be OK this year with the Hollowtechs but I don't suppose I'll get 50,000 out of them! I'm rather attracted to the Hope BB not only is it good kit but they are made in a village, Barnoldswick*, near where I grew up in Yorkshire. Hey ho perhaps it's time I got a new bike. You could call the one I've got now The Bike of Theseus.

*Bet you pronounce it wrong, a lot of people in the UK do too. They also make Rolls Royce jet engines there, that's what the B in RB211 is.
** Since I first wrote this I've googled "pronounce Barnoldswick" and most of the results it comes up with aren't even close to the way the denizens pronounce the name!

Early failures on Hollowtech II bottom brackets can be caused by poorly faced, out-of-alignment bottom bracket shells.  If those reporting the early failures have badly aligned frames, it would explain a lot as no bearing will tolerate much of that.
Thank you Dave that makes sense.

Let me say something about how 'improvements' come to market. It's budget time and Mr S is at the head of the table on his one hand is Mr HT who has developed the Hollowtech product on his other hand is Mr ST who oversees square taper manufacturing. "So" says Mr S to Mr ST "what are your requirements for next year. Mr ST says "our machinery is worn out and we need some spendy new specialized plant, broaches etc. Those square tapers are quite tricky"
Up pipes Mr HT "We're ready to go now with our new line, and we use cheap off the shelf hardware i.e. a piece of tube that we can machine a spline on with any one of a hundred CNC machines we already have. Thanks to this we can sell at lower unit cost and higher margins and no big capital investment" Then Mr S says "Mmm the racers like HT. Looks like a no brainer. Tell the marketing boys to sing Hollowtech's praises".

NB No discussion of whether it's a better product for the average Joe It all boils down to making the most money

I've no idea whether Shimano operates like this but over a lifetime in manufacturing I have sat in similar meetings.

No I have no personal proof and I didn't come to that conclusion, other people did. As for personal proof, of course not, that's why I've raised this question. Check the link to the CTC website. In particular TrevA who says I got sick of replacing the bearings on the Hollowtech every 2-3000 miles. The general opinion there is that Hollowtech BBs don't last as long as STs. Russ I've as much reason for taking TrevA at his word as I have for taking you at your word.

Why are you wasting the time asking these questions?  You don't want to believe this other person you cite on the other forum, and you don't want to believe my opposite opinion.  I suggest you resolve this conflict by flipping a coin.  Heads this bottom bracket/crank, tails the other.
Because questions had been raised as to Hollowtech durability I came here to get the experience of people who have actually done some touring with these things. Yes, judging by the tone of the only responses I got it was a waste of time

Curious how you came to this conclusion that "ST BBs last much much longer than Hollowtech."  Do you have any actual personal proof?  Or are you just making up stuff off the top of your head?  I am aware most science and rebuttals of science are done this way now days.  Testing, proof, observation is so out of date.

I don't know who told you about 2,000 mile failures  but that seems absurd unless they criminally abused their bikes.
Again, check the link.

Sorry I can't get the link to work the second time.

Gear Talk / Shimano Hollowtech experience anyone?
« on: March 08, 2016, 11:13:49 am »
My LBS talked me into replacing the original square taper (ST) bottom bracket in my 520 after 51000 miles with a Shimano 105 Hollowtech BB by saying that new ST cranks weren't available (it seems that it's only Shimano ST cranks that aren't available). Now, from the CTC forum it appears that Hollowtech BBs don't last very long, < 2000 miles some people are saying. This has got me worried, it seems that ST BBs last much much longer than Hollowtech. I've got a Route 66 tour coming up. Should I be looking for an ST BB or possibly replacing the Shimano with a Hope BB or am I looking at replacing a BB somewhere in New Mexico ( I was going to write NM but that's overdoing the initials  ;D)

Right now I'm leaning towards doing a preemptive replace of the Shimano with a Hope because I like the feel of the Hollowtech setup and the changing is superb. Waddya think?

At the least I can take a spare Shimano BB with me, they are only $20 at REI and don't weigh much.

The only time I ever tried to register was in Scott City Kansas. I said to the cop in his car: "It says here", pointing to the ACA map, "I'm supposed to register with the police" "Consider yourself registered" said the cop.

General Discussion / Re: Dogs n' bears
« on: February 16, 2016, 08:09:11 pm »
I've only once come across a bear. Last year in BC on the Icefields Parkway about half a mile from Bow Summit, the highest point, I was grinding my way to the top very slowly and a grizzly bear walked into the road about 10 yards in front of me. Needless to say I stopped. He/she stopped. Bang in the middle of the traffic lane and looked right at me. (It's amazing how much like Teddy Bears they appear, imagine a Teddy Bear's head the size of a cow's.) Right then a car pulled up next to me and the lady in it asked if anything was wrong. I pointed mutely at the bear not wanting to get his attention any more than I already had. The lady gasped. About that time the bear decides to go on its way across road and that was the end of the adventure.

I sort of regret not getting a picture but a comment above tells me I did the right thing. TBH I thought of getting a picture at the time but was scared of getting the beast's attention any more than I already had. It was also the only time I've ever been glad of traffic.

When we got to Oakland CA for a ride down the coast I decided we needed a chain long enough to lock both our bikes up. I went into a bike shop on the waterfront and found a Kryptonite chain for $62. So I bought one and well it served. After I got back I went to my LBS, Burien Bikes,

Burien Bikes, huh?  Is it the one called Bicycles West just east of Ambaum and north of 152nd?  I grew up going to that bike shop in the 1950s and 1960s and have bought bikes and much gear there.
That's the place. Actually it's new name is Burien Cycle. It used to be a branch of Bicycles West but is no longer. I believe it's independently owned now. Their prices always seem pretty good.

$30 is a cheap price for not having to go all the way home to get a chain.
Very true John but it is quite a difference. But then if we never forgot anything we'd be perfect - actually I didn't forget, it wasn't until someone on the train down suggested I needed a good lock in San Fransisco that I even considered it. I did have my flimsy cable lock that I believe the ACA says is all you need on their tours but I don't suppose they spend much time in San Fran.

After I got back I went to my LBS, Burien Bikes, for a chain of the type that makes your bike go and what should they have but the same Kryptonite chain I had bought in Oakland for $32!

For many years I've rode a Trek 520 with  51-38-24 Shimano 105 square taper cartridge bearing crankset 9-speed 11-32 rear. My LBS tells me the old 105 stuff is no longer made and as the BB was showing signs of wear I had them replace it with Shimano FC-5703 external bearing triple (there's Youtubes on installing them) this set comes as 50-39-30 and I had them put a 24T ring on the bottom. Nominally this is a 10 speed crankset but it works just fine with 9-speed. I had some trouble with rear shifting I thought was a chain size problem that turned out to be a worn out shifter detents, changing to friction shifting mode fixed that though it takes a bit of getting used to.

I think you can get the FC-5703 set for about $120 on the net and you may have to buy a tool to install the bearings for <$50.

I had SD-7's on a Surly Cross Check and the braking power (with Kool Stop Salmon pads) was plenty good but they were very squeal prone and nothing I did quieted them down reliably.  Substituting road brake pads and holders for the OEM ones helped a bit but not enough.  My solution was to sell the bike and replace it with a Pacer and caliper brakes.  These are always quiet.
Looks like it's a design issue with the 520, some marriages are just not made in heaven. Possibly the SD-7 and 520 forks are just not made for each other so to speak. I also replaced the original levers (no idea what brand they were) with Tektro SR520s, it may have been a combination of the two replacements that fixed my problem. The back brake is still the original SD-7 and it's just fine, quiet and works well.

Back to the OP's question. I find the 520 a really comfortable ride and on fast downhills with four panniers very stable. To my mild surprise when I got my rig weighed at the ACA HQ on my last tour from Jasper to Portland I found I was hauling 45 lbs! No wonder I was slow on the hills.

On the Trek website the three main beefs are: uncomfortable saddle (The original was horrible I now have a B17 - ahhh joy), brakes could be better (see this reply) and heavy (It is a steel touring bike though MrsJ's Novara Safari is considerably lighter)

I had a similar experience to Westinghouse; whizzing down the hill into Idyllwild CA. The stop sign was obscured by foliage and I ended up braking way too late and shooting across the intersection. Luckily there was no traffic. With lousy brakes stopping becomes like planning for retirement you have to think so far ahead.
