i'm in the process of cross-grading my drivetrain to 1/8" and have found this neat looking chainring, the "rocket track". it's here:
according to the ad copy it has "10 drilled holes- making it compatible with virtually all cranksets!", which sounds appealing since i have a 110bcd crank that i'm fond of.
so... my question is: has anyone used this or know anything real about it? is it worth my effort and money to get this thing?
