Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

will a 28" tubular fit a 700 rim?

Like a moron I accidentally ordered some 28" tubulars from PBK not noticing they weren't 700s. Will they fit? After about 10mins of trying I'm inclined to say no... The strange thing is that 28" is longer than 700mm, so they must be measuring different things.

Who uses 28" wheels? Anyone need some cheap Continental Giro tubulars?

its just the way that Continental labels their tubulars.
I have Giro's, Sprinters and Competitions on 700c rims (and tires all labeled 28")

Make sure you really stretch the Giro's before mounting them, it just takes a bit
of patience.

Those are the right size. Try harder to stretch them on, because conti's run really small.

And just for the record - standard tubulars will fit on a 700c clincher rim too. Good way to stretch out and pressure test new tubies before gluing them on the sew up rims.

Thanks, you made my day!!!

Now I've got to ask...what's the best way to stretch tubulars before you put them on the rim?

Is there more than one way to stretch tubulars?

Bicycle tire size naming conventions are a mess. As an example, 700C, 28" and 29" tires all fit on the same diameter rim which is smaller than a rim for 27" tires. If you want a measurement useful for comparison, use the ISO standards. http://www.sheldonbrown.com/tire_sizing.html.

YOU can't be serious asking that question!

But just because you did, yes. Put it on a tubular rim, put it on a clincher (700C) rim, stand on the bottom and pull up, wrap it in your arms and use your arms, hook it on the wall and hang a 100# weight ...

But not all tubulars need to be stretched, and I think anything other than the tubular rim method can run the risk of damage due to excess tension.

for contis, i just put them on the rim with no glue for a few days. Easy to mount after that, and you don't have to worry about tearing the base tape.
