I got my hands on a 700c flip-flop wheel. Would I look like a total loser if I use it as my rear wheel with a 27" wheel on the front? I don't really want to convert the front, because that would cost money. Or should I use the 27" rear wheel and save the 700c flip-flop for another project?

You can do it. It looks kind of goofy, but oh well. Your only problem might be the rear brake not reaching, if your bike is so equipped.

27" front with 700c rear is a death wish. Your bike will no longer turn or handle properly. You might as well just jump out in traffic and get it over with.

It will work fine, I have several thousand miles on my commuter with 27" front and 700c rear.

LOL. Sweet. I will probably use the old 27" wheel as an option for another gear ratio for the days when I'm riding more hilly terrain or longer distances. How "goofy" does it look? Can you post a pic?

don't have any really good pictures at the moment....

Nice, I can't even tell. I was really only concerned with the look with the difference in wheel diameters. But it isn't really even noticable. Thanks!

The difference in diameter is only 8mm, so only 4mm in the radius. If you use a fat tire on the 700c and a skinnier one on the 27" they should be even closer in diameter.

The difference is not a big deal. And as others have mentioned, you can bring the diameters closer to each other by sticking a beefier tire on the 700c. I also did this while waiting for the day I could replace my 27".

its simple to do. but when you replace it with a 700c up front, it will feel really different. when i swapped out my 27" front the whole bike seemed different.

did you swap out from an old wide 1 1/8" or 1 1/4" front tire on the 27" wheel to a modern high pressure narrow road tire?

just the difference in tires will make a huge difference, much more so than the wheel size (IMO).

It had nothing to do with the wheel size swap. You won't feel < 4mm of reduced height at the front of the bike.

This bike I had setup that way



until I bought a killer new 24 spoke radial front wheel. I had it for two weeks and the bike got stolen.

I think the difference is hardly noticeable.
I mean, eventually you will bend a rim if you ride hard, or simply desire a different wheelset. Then you can replace em, as far as performance goes, you wont notice much.

I have a 27 rear and 700 front b/c I didn't want to spend the extra money on the beater SS. No probs.

if the change was from a 27x1-1/4 to 700x23 theres a good chance the difference would have a noticeable effect on the trail and handling..
and it would be > 12mm
