Gear Talk / Re: Touring wheel configuration
« on: May 23, 2014, 04:49:41 pm »
I got over-fancy and built up a set of touring wheels on Ultegra hubs, which was a mistake.  The rear hub was replaced twice under warranty.
I have to ask how the Ultegra hubs failed.  Basically all Shimano road and MTB hubs have a stellar reputation for smoothness, durability and ease of maintenance and my experience with them bears this out.  So I'm really interested in what happened to yours.

The one real problem with MTBs is their straight handlebars which give only one hand position.  This can be a problem and cause numbness (aka "handlebar palsy") on successive long days of riding.  At a minimum, if you don't already have them, add bar ends to give you another hand position.

The rim vs disc brake debate is still raging and can get pretty heated at times.  It's almost as bad as the Shimano vs Campy arguments of the past. 

So this is MY opinion and MY take on brakes.  Others can (and will) chime in with agreement or disagreement as they wish.

Bicycle stopping distances are not limited by their brakes but by their tire grip and the tendency of the rear wheel to lift under hard braking so claiming one form of brakes provides better stopping then others is misleading.  Any decent rim or disc brake will lock both wheels quite nicely.  So the main differences are:

Disc brakes may work a bit better in the wet but good rim brakes with good pads are very close behind. They are also a bit better at heat absorption on long downgrades and keep the heat away from the tires.  However, they can be overheated if used poorly just like rim brakes. 

Disc brakes don't cause rim wear and this can be a consideration for true off-road MTB use but road rims last a long time anyway.
 
Disc brakes complicate and slow wheel installation and changes.  Probably not a big issue until you have a flat in the rain as it's getting dark.

Disc brakes are heavier and their frames and forks are heavier as they have to be reinforced to take the braking forces and discs are less aero but these are all mostly non-issues with a touring bike.

Front disc brakes used with standard downward facing fork dropouts tend to eject the front wheel under braking forces.  It is ESSENTIAL that a fork with good "lawyers lips" AND a strong internal cam (Shimano or Campy type) quick release skewer be used.  Some fork designers have adopted either front facing dropouts or, better yet, through axles to avoid this problem.   The Disc LHT seems to have standard fork dropouts so I assume they have substantial lawyer's lips.  If you go that way keep the qr skewer TIGHT.

Mechanical disc don't have the modulation or ease of operation of the better hydraulic models but they make it up in simplicity and ease of repair.

To me disc brakes on road and touring bikes are still a work in progress and I expect developments in the future will make them more user friendly.

The LHT is spaced for 135 mm hubs so that's not an issue.  I agree than any Shimano hub is a good choice and the XT is probably the "sweet spot" in the MTB lineup.  It's available both with and without disc brake rotor mounts so buy the one to suit your brake choice although the disc-ready hub is fine for rim brake wheels too.   

Shimano's web site no longer lists the XT hubs as separate items and you may have problems finding 36 or more hole hubs these days as 32 seems to be the standard.  However, Jenson still lists the XT in disc form with 36H drilling: http://www.jensonusa.com/Hubs/Shimano-XT-M756A-Rear-Hub¬

If you have the LHT frame, the brake type has been defined already.  If not, this is going to be a long thread as opinions and recommendations will be all over the place. 

A bit more info is probably useful:

1. What  type of touring do you plan?  Fully loaded and self-contained?  "Credit Card" with minimal luggage and no camping or cooking? Van or car supported?
2. What type of terrain?  All paved roads?  Some dirt and gravel roads? 
3. How much do you weigh?
4.  Are you going to be riding in "developed" countries only (i.e. always near a bike shop and cell phone service) or in undeveloped and remote countries and areas? 

All of these factors will have an influence on the type of wheels and tires and brakes you need.

Hi! I live in Bend and don't have time for the full E--->W route at this time, but would love to hook up locally. Let us know when you'll be in Central Oregon. I may be able to swing a few days heading West.
You mis-read the OP.  He is heading EAST.

Gear Talk / Re: Advice on a Bicycle for Trip to France

If money is tight then I would stick with the Bike Friday. A loaded down bike on tour is a different animal from a racing bike. You ride it differently, it feels differently. I actually like a loaded bike. Your young, a few extra pounds aren't going to make a lot of difference. I haven't tried the case as trailer. You could always store the trailer and just use panniers. Picking out a tour bike is much easier after you have done some touring.
I'm beginning to think this is the best solution if money is tight and the model Bike Friday you have is suitable for racks and panniers.  I've ridden a Bike Friday a modest amount (my son-in-law has one) and, while it's initial handling is different from a 700c wheel bike, you get used to it pretty quickly.  After that, it's just another bike and only seems strange when you look down.

« on: May 09, 2014, 11:54:07 am »
There is probably more to it than just changing the cassette.  If you have a road rear derailleur, most won't handle a 32T large cog and certainly not a 34 or 36T.  You will most likely need a MTB rear derailleur and also a longer chain.

A bit more information would be helpful before any specific recommendations can be offered.   How many riding day and miles per day have you planned for? Are you camping or staying in motels, cooking on your own or eating in restaurants?  What type of bikes and luggage capacity will you have?

As to training, the simplest recommendation is "ride lots" and try to train in terrain similar to what you will encounter on the trip.

I have been managing an active lifestyle with a fasting BGL of <100 through eliminating grains and eating 100-150 g carbs/day....
Uhhh, if grains aren't carbohydrates, please tell me what they are.

I will also bet that solo travellers receive more "acts of kindness."
About the only type of bike tourists that might receive more "acts of kindness" are a couple (man and woman) traveling together, particularly if middle age or above.

I had an '07 Safari that was stolen, replaced with an '08. I hate the '08 frame.
Why?

My, my, we all do feel strongly about our chains.

dkoloko, where can I find that Berto reference?  Google fails me.
Yes, in many bike forums "lube wars" are second only to Shimano vs Campy wars in the amount of heat they generate. 

As to the Berto reference, I don't know either but Velo News magazine has done guantitative lube tests in the past couple of years and they should be accessible on their webs site: velonews.com   And yes, paraffin did win their tests but they were dealing with newly treated chains, not durability.

A caution.  Even if riding East to West and staring in mid-May, take clothes for cold (say mid-30's) conditions.  The Appalachian /Blue Ridge mountains can produce cold days and nights and even in summer and the Rockies are always unpredictable.  Don't let the Great Plains in mid-summer fool you into sending the tights, jackets, etc. home.   

The "conventional wisdom" is that the prevailing wind is from the West so many riders go West to East to take advantage of expected tailwinds.  Apparently that is a myth and the headwinds going West to East can be just as pervasive as the other way.

Been there, done that, gave it up years ago.   Benefits are extreme cleanliness and decent lubricating properties when fresh.  Negatives are very poor durability, dreadful water resistance and a difficult and potentially dangerous application technique.  It's trouble enough to do at home, I can't imagine trying to do it on a tour.
