Can you add chainrings onto an 8 speed without replacing the crankshaft?
Can you add chainrings onto an 8 speed without replacing the crankshaft?Lets just assume you are talking about 8 in the rear and a standard road double crankset. Yes,and depending on BCD you can ditch the small ring buy what is called a tripilizer ring and then bolt a third granny ring to that. You also need a longer BB spindle.Somewhat pointless, unless you are dealing with a nice crankset you want to continue using.

the bike has a e. thirteen chainring system. it has the 8 cassettes in the rear. I'm kind of new so bear with me. for steep climbs i was hoping to add a granny ring but after seeing the parts i'm not sure if i can. anyone familiar with e. thirteen?
