|700 wheels replacing 27"?||Noam|

I need new wheels for my bike and have been offered a good deal on a pair of 700cm's. Is it a problem to replace my current 27" set with these?

|Yes it may be a problem 'cause your brake pads may not reach the brake track on the rim... may not be a problem if you have long-reach brakes with enough adjustment, can install drop-bolts if your brakes don't reach, or don't care to ride with brakes.|

|you'll need new tires and make sure thet you get the right type of rear hub. If you've got a freewheel on your old wheels, you'll want to make sure your new wheels are for freewheel, if not you'll have to buy a new cassette and then probably run into a cosmic butt-load of annoying compatibility issues. If your old wheels are cassette, then you'll need to make sure the free-hub body is the same size and same type (shimano7,8 or 9/campy7,8,etc.) as the one you have. This might be a good time to upgrade to a new bike if you've been thinking about it.|

|If the old dropouts are 126mm and the new wheels are 130mm, you can probably just bung it in. If they are 120mm, though, probably not. You also didn't say anything about the # of cogs on the old/new wheels, which can cause compatability problems.|

|My commuter/rain bike is an old Trek with cantilever brakes and 27-inch wheels. When I got tired of looking for decent tires, I tried the 700s from my wife's semi-abandoned Bridgestone (she rides a mountain bike most of the time). They slid right in--all I had to do was lower the brake pads a bit (easy with the cantis, maybe impossible w/conventional brakes). It's friction shift, so there wasn't any problem there, and spreading the dropouts 4mm or whatever was a no-brainer.
So it's worth a try. As the other posts have mentioned, though, you may run into problems I didn't have. How about borrowing a friend's wheels for a minute to try it?
