650c wheel on a 700c frame?(8 posts)

650c wheel on a 700c frame?TheJoker

Is there any way to retrofit some sort of mechanism to make the front brake work on a 650c wheel if the frame is 700c?
That would be a big NOPEKerry Irons

The reach is significantly longer - we're not talking 27" vs. 700c, which sometimes works. The difference in radius is nearly 2 cm, and you're not going to find brakes with that much adjustment, even if you could find a drop bolt. Give it up and ride the right size wheels.

You could stick a 650 fork on the front!
Get the low rider look going on!
Pretty retarded if you ask me though.
You'd always be going downhill so it'd be faster. (nm)Spoke Wrench

The mechanism you will need is the following: A hacksaw and a welding torch.

Sure, outfit the frame for disk brakes, buy a CX fork and run whatever size wheels you want.

Figure out how much further away the new brake surface is from the original. Aquire a hunk of metal and drill 2 holes at that found out distance apart (700-650)/2=approx 25mm. Bolt one end of the new braket to the fork, and bolt the brake to the other end. Your brakes should now be set so they contact the rim properly. Now, if the whole thing actually stops the bike is another question, or will the whole thing just rip the bracket out of the fork and bend the brakes into a pretzl is for you to find out. Tell us how it works.

Also, the stem police will be watching.

Jul 6, 2003 4:51 PM removing your front brake, wrapping electrical tape around every tube, and cutting your bars down to 6 inches across. Then ride against traffic on 6th avenue during rush hour.

(I've noticed two messengers in the past week riding 12" front wheels with 700 or 27 inch rear wheels. Looks cool in an "I don't care what I'm riding so long as it rolls" sort of way.)
