Would you ride with this clearance?

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

Would you ride with this clearance?

so i was toying with the idea of some 28's on the ciocc, for longer rides (on rough roads at that).

anyway the bike wasn't meant to take such big tires but they barely fit. test ride went well, but i'm hesitant to use them for longer rides.

would you ride this?



this one is a better angle:


so maybe 1-2mm of clearance...

i've ridden with 25's on this bike with no issues (clearance wasn't much better, but a little) with no issues.

the main thing i'm worried about is a rock or something getting caught in the space, and stopping the wheel... but maybe it would just crush the rock? one can always hope.

thx for reading - what say you?

Yes. My TT bike (as well as many others) is designed to have about the same clearence. If it doesn't rub, it shouldn't be an issue. If you ride in the mud or through a lot of debris it could be a problem. But relativey clean roads there shouldn't be an issue

that's kinda what i hoping, that if it wasn't rubbing then it's ok.

i do ride on crappy roads with dirt/rocks on the shoulder sometimes, but not really off road. i'm hoping at worst it'll just scratch the paint or somethin.

thx!

Any rock or stone that is small enough to get past your rear brake caliper wont be big enough to cause any problem. It would just compress the tire and roll through. Ride it.

My friend used to train like this in the Central Park Spring training races. We used to call him "thunder thighs". He took them off during the summer and FLEW.

I don't think a rock small enough to fit into that space could stop the wheel. At the worst you might have problems with debris stuck in the tire scratching the seat tube.

It's a good thing that frame has a braze-on front derailleur hanger.

just make sure the clearance is the same when you're on the bike as it is when you're off.

also, a little tried dirt on that tire could rub some paint.

if you don't care about a possible paint-damaging rub, i think it's probably fine.

28's on a Felt F-80
Tiny rocks could make some marks and cuts.
