- Are you really sure about this? Most of the Shimano cranksets that
- I've seen are available in only 2 types: 28-38-48 or 24-36-46. Since
- 24-36-46 is a stock set available from Shimano, I'm sure that there are
- thousands of bikes out there with this combination. And They seem to work
- okay.
- And then there's my bike, with 30-40-50 on the front, and it works
- okay.
- Maybe you just mounted the chainring wrong?
-
- (p.s., I'm kinda curious about this, since I want to replace that 30 on mine
- with a 24 soon)
