I was wandering if there is an easy way of knowing how long your chain should be...
do i put it on both biggest rings and look to have no give at all or is there another way of working it out?
I have a brand new XTR (CN-7701) chain with 114 links and I have an 18.5 Marin frame, a 9 speed XT rear casette and a 175mm FSA Crankset.
any help would be great, thanks !!
