So i just bought a frame and it comes with a DX crankset. I think that it had a 7 speed orrigionally in the back. So if I upgrade to a 8 speed do i have to get a new crankset to fit the chain properly? The cassette is going to be an SRAM PG-850, and a PC-68 8 speed chain. So should i upgrade to prevent wearing my components.
