hi,
i bought a new crank for my old mountain bike, and on the large chainring it says: "shimano IG
chain only"
how critical is this? i don't know what kind of chain it is, but it's new enough (barely stretched
at all going by the 12" link to link check) that i'd rather not buy a new chain if i don't have to.
is there some simple articulation of what my chain should or should not look like in order for it to
be compatible? or is there something on my old crank i should look for? my old crank has 'flat'
chainrings - no 'ramps' for quicker shifting. the new cranks' chainrings have these 'ramps'. the
chain came off of a bike with 'ramps' and worked fine as far as i know.
is the IG refering to those 'ramps'?
thanks,
david
