Title: A65 drive sprocket
Post by: Mike Farmer on 29 October, 2017, 20:15:06
Hi.

I'm considering putting a 29 tooth primary drive sprocket on an A65 that I'm building. All my current info is for 28 teeth.

So whilst I understand the gearing affect. will be a problem with the primary chain. I can only find A65 info for an 80link chain

 (which I imagine will be too tight) or an 82 link.

So if I use the 82 will I have enough adjustment. Your advice please.

Incidently the reason for this is quite simple----I already have a 29T sprocket.

Don't know what it came off???????

Mike ;D ;D
