Track Cycling: Velodrome Racing and Training Area - Mixing 3/32 and 1/8
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.
I bought a track bike on ebay, it has 1/8 chain, 1/8 cogs but a 3/32 chainring on a 130mm bcd crank. I'm having a hard time finding 130mm 1/8 chain rings, is it a bad idea to mix and match 3/32 and 1/8?
Or, where can I find a 144 bcd crank for not too much money? The bike is a 2005 fuji track pro, what types of crank will work with the bottom bracket?

as long as the chain is wider than the cog or ring you're fine. 1/8" chain works on 3/32" components. not the other way around.
and which cranks came on the 05's? was that miche? i believe they are 135 and business cycles sells them (either way, you can get rings at business cycles) stronglight makes a good 130 bcd 1/8" chainring. i'll dig up the link.

130 mms? isnt that campy and shimano BCD? actually yes u can mix both as long at the chain is 1/8 obviously.
Secondly as long as u know what kind and lenght or the BB axle u have in there more than somebody can tell u what it fits there. Since I'm a campy/italian track dude, is hard for me figure it out what kind of bb u have there but I assume u have an isis or something shimano compatable stuff in there.
Good luck :)
130mm is typical road bdc. You can mix parts that way, but it will be a bit smoother if you get a 1/8th chainring. the sugino messenger comes with a 1/8th chainring but is 130mm bdc:
