Re: Belts 9mm or 15mm?
15mm is what I would feel safest with in a drivetrain, particularly with the smaller pulleys typically used in west coast drives. 9mm is very marginal for most standard drivetrains using 24T or 27T pulleys, and can definitely fail. Once you go above 30T (for example, with a dead axle setup bolted to the wheels directly), you can probably get away with 9mm. It's a little extra space, but the result is a zero maintenance, highly reliable drivetrain. Go for it!
