My touring bike currently has
26-36-46 RSX crank
12-32 shimano "P' 8 sp. cass
Deore LX rear derail
RSX front derail
RSX STI Shifters
Can I put a 22 ring on the smaller one
(I need to put little lower gear for loaded touring
but short of changing the whole crank to
something like Deore 22-32-46, may be I can just change
only the small chain ring??
I know there's ring-difference that is not allowed,
just not sure how it will be for me.
