Using 700C wheels on (26" x 1 3/8") frame

Postby fixie_noob » Sun Jan 30, 2011 6:29 pm

Hey guys

I've got an old Ricardo racer frame with original wheels measuring 26" x 1 3/8" (or 37-590), which I believe is also known as 650A or English 3-speed.

I'm thinking of converting it into your average fixed-gear bike, though I wanted to ask: will 700C wheels fit?

Help!

How much room between the tyre and the fork crown and the brake bridge on the rear stays? You should have more than enough room for 700 x 25c or 28c, but not so sure about 32mm tyres.

There's about 25mm on either end - will that be enough?

I was looking at 700 x 23 wheels...

Also, I've read that putting new wheels on these sorts of bikes sometimes cause problems with the brakes - will I be able to adjust the brakes so they reach the wheel?

Thanks for your help!

i find a bike that has very close tolerances very appealing to look at but 25mm gap it mite just be to tight

You'll need to measure the distance from brake pivot hole to the centre of the rim side-wall. You'll most likely need new callipers - they'll be something far better than what you have on the machine at the moment.

Awesome - but the wheels will most likely fit with that much space?

Hi,
I just completed a makeover of an old Raleigh 3 speed.
The 700c wheels fit great with 23mm tyres, I put on some shorter reach brakes though.
THe hub spacings are odd - 90mm for the front and 110 for the back.

I built up the rear with the 3 speed hub, so that was easy, but had to modify a front hub to reduce it to 90mm
