I'm running a stock Truvativ Powerspline BB 68x108 with Truvativ Touro 48t Crankset.
I'd like to replace both.
Would my chainline be affected if I got a BB that is 68x107?
I'm so new to Bottom Brackets, I'm replacing this BB/Crankset because it's a year old.
Or do I need to? I've ridden it hard since last January...
Any suggestions or advice is great help, thanks!
