Can you use a 9 speed chain on a 8 speed drive train? My friend has some extras lying around and he gave them to me… not one to turn down something that was free…
any help?
If you are running bar ends, you could just swap out the cassette to a 9 speed and friction shift, the 8sp rear der. will work as such. The 9 speed chain is more narrow, so you should get the offset inner chain ring for up front also. I don’t think the 9 speed chain would shift well on an 8 speed cassette due to the distance between cogs and the narrowness of the chain. However, I’m just speculating.
