Coming from a mountain bike and road bike background, I have been thinking of getting some cross wheels for my Specialized Stumpjumper for winter commuting.
A. Will this work? Is it compatible?
b. If so, what's a good strong cross wheel that won't break the bank?
Thanks guys and gals,
A

Hmm. I really don't think the Stumpjumper frame can take 700c wheels. Your best bet might be to look for some faster mtn tires -- not quite road slicks, b/c you'll still want some traction for winter.

this will not work. you can't put 700c wheels on a mtb frame (that is, a mtb frame meant for 26" wheels). but, you can get some 'cross tires that will make commuting a bit more pleasurable and efficient. Kenda makes some nice light ones for 26" wheels.

if you have disc brakes, yopu should be able to fit 700c wheels just fine. one guy i know built up a set of open pros with lx hubs for his stumpy. seems to work fine with 25 mm tires, with ample clearance for more.

so a 700c wheel will fit in the front fork?

depends on the fork and the tire, i guess, but eric's bike seems to have enough clearamce, you could always just borrow a road wheel from your lbs and see if it fits.

No disc on my Stumpy, I think the 700 will likely be a problem. Will give it a shot tonight.

There is someone around here or MTBR.com that has a mtn. frame designed for 26" wheels and has 700c wheels working with cantilever brakes.

As far as the wheel and tire fitting, that shouldn't be an issue. The issue is the brake pads reaching the braking surface of the wheel. Tektro has cantilever brakes that have cylindrical arms where the pads can be adjusted up and down over a very long range. I found a pair on eBay for $19 new. I have not pieced my rig together yet (converting a circa 1990 Schwinn High Plains to a cyclocross/commuter bike) but a test fit with a 700c wheel with the cantis in place appeared to work. Hopefully by the end of this week I can tell you if it will work well or not, but I'm following the lead of someone who already did this and it works for him.
