I know this is probably a stupid question in some way or another, but will 700c wheels fit a moubtai bike frame or no? Lay some knowledge on me.

Not a regular mtb frame, but if you look for a 29er frame, its a mtb frame designed for 700c wheels.

probably only brakeless. i've fit 27" wheels on an mtb frame before, and 700c wheels are smaller. thing is, the cantilever brake bosses are way too low for either of those wheels.

however, it may come drilled with a hole in the front fork, road style, that you could attach road brakes to, as well. i have an mtb frame in my garage that's just like that.

but, you could probably only do it brakeless, my guess.

does it have vertical dropouts? you might also have to use the magic gear calculator.

many 26 inch frames will fit a 700c, especially suspension corrected ones.

however, you'll have to use disc brakes, and it'll handle like crap.

humancongereel

really? haven't done much riding on a bike set up that way. how's it affect the handling?

sivat

My mistake. I have a stumpjumper hardtail and 700c wheels with 23mm tires would rub in the back.

ink1373

it ****s up the trail numbers really badly. that accounts for most of it.

humancongereel

ah. got it. so no snaking through traffic like a stealthy ninja type? i hardly expected that, but i'd like to know...

The thing is, I've got an old mountain bike that for reasons of economy and broken parts I am turning into a single speed (if the parts ever get off back order). This bike will see 99.9% road action in the form of commuting and I wanted the skinniest tires/rims possible. Am I stuck with 1.25"-1.5" tires?

humancongereel

no reason you can't go skinny...too wide will rub and too skinny will...ummm....uhhhh...

lots of old mtn bike frames fit 700 wheels.. i have a bridgestone that fits 700s with 35c knobbies on it.. and you can buy canteliver brakes with enoough adjustment for the wheels.. they are on ebay all the time..or if its drilled you can find brakes that fit.. i had an old novarra designed by scott nicol of ibis that fit 700c wheels just fine also..plus you can always toss a road fork on the front..

humancongereel

exactly.

A guy I work with at the shop has an older Indy Fab mtn frame that he runs with 700x44 and a surly crosscheck fork.
It's a homebrew fixed 29er that he can get through some tricky trails.

sivat

I've seen 1" tires for a 26" rim. This one for instance. A 1" tire is about equal to a 25mm in width.

my c'dale bad boy is a caad4 mtn frame set up with discs and 700c wheels. handles great, fun to ride, comfortable, and fast.

darkmother

The outside tire diameter is nearly the same, but the brakes will not line up. You can make something work though. Especially brakeless.

Disk.
Brakes.
Rule.

No problem on my Schwinn Moab frame for 700c wheels and even fairly fat tires.

dutret

Unless you are insanely fast pressure matters alot more then width. There will be very little functional difference between a 1-1.25" 110psi tire and a 23mm 120psi one.

Thanks for all the good info guys. Problem solved I think.
