Can I use a 10spd chain and cassette with a 9spd drivetrain (and everything else including bar-end shifters)?
My 9spd chain is bent. I have a brand new 10spd lying around that I’d like to use to save some $$. I also have a 10spd cassette on my roadbike that I was thinking of using for this tri bike (p3)…esp since I was hoping to use the 10spd chain.
Any help is appreciated.
