Default Re: Cranbrook, Chain shake/flap/slap

The tensioner wheel MUST be aligned with the chain path. In most cases this requires a slight twist to the tensioner bracket. Clamp it in a vise and using either a large adjustable wrench, vice grips or whatever you can grip the bracket with, twist it so the centerline of the tensioner wheel is perfectly parallel with the chain. The chainstays on most bicycles are not parallel with the rear wheel or the drive chain. When the kit tensioner bracket is clamped to it, the tensioner wheel aligns with the chainstay (frame) and not the chain. That's where the needed twist comes in.
I just gotta do a picture tutorial on this some day.
