I have the Avid bellcranks. I was able to get the issue resolved though
Manual seems to recommend the 81t spur. I run an 8.5t Reedy and was going to start with 23/75 (close to what I'm using in the 22 right now) but was wondering if the car favors having the motor further back and that is why they're using the 81t spur in the manual?
