I want to put a e-13 bashguard on my bike, my outer ring is a 44 tooth, the biggest one they have is a 42, so will that work?
Usually we take off the large ring and purchase a guard to match the size of the middle ring.
And my rear tire is 2.1 and I would like to go to a 2.3 or 2.5 how much wider is that?
I would say the difference would be 2.5 – 2.1 or .4 (or 2.3 – 2.1 = .2). 😃
