Bicycle Mechanics - Chain length w/bigger chainring
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
Just a quick question: If you were to put a chainring that is one tooth larger on your bike with the existing chain, it should fit, correct? Is there an easy way to tell if it's alright?

I assume you are talking about the large ring, if not then of course it will fit. I would put it all together and with the bike on a stand or upside down check to be sure it will go from the large ring in the front to the large gear in the sprocket. I know you shouldn't ride this combination very often, but I wouldn't want to not be able to get into it and drom the chain if I tried. The Shimono website says while it's not a good idea to cross the chain that way if it were really bad they wouldn' have built it.

3 methods of working out chain length at:
one tooth shouldn't make too much of a difference. the difference is something like 1/8th of an inch. of course, you should do the big/big test once the new ring is on just to make sure, but i'm pretty confident it'll work.
Great, thanks guys. I'll just try it.
