i noticed on my bike that about 2-4 teeth on each of the 3 front chain rings looks like they were
filed down or something..they werent uniform in size with each other... it looked more like a
manufacturing defect than something that got chipped or broken off.
i took it to a shop and they explained that they are there to facilitate shifts... i looked at a few
other same bikes and, sure enough, they had the same 'feature'. however, none of the other bikes
seemed to have this same design on the chain ring.
so maybe it suggests that the drivetrain is poor so that it needs the help of these shortened teeth?
i dont think the more expensive bikes had the shortened teeth
its a suntour xcc-300 or something crankset, btw
