I may be wrong but are some chain guides mounted by pressing it with the bbcup? If so what size bb do they fit.
Im thinking of purchasing this to help reduce chain suck while pedaling. I mostly do technical XC or trail riding ( really dont know the difference) so I dont need those full blown duel roller chain guides. Anyhow if my bb size is 73 113.5L would I beable to mount this. I would like to keep my big chain ring if possible.
what do the sizes mean on the this one?
Thanks for your help.
