A friend of mine has a mountain bike with slicks that he uses as a
commuter. The commute is relatively flat, about 30mi round trip. He
currently has a 42/32/22 crankset, and he uses only the 11 and 12t
(mostly 11t). As a result, he uses up cassettes virtually every 2-3
months or so, such that a new replacement chain skips on those two
cogs.
Is there a cheap source for 11t and 12t Shimano cogs, such that
replacement cost of 2 cogs doesn't approach the cost of replacing the
whole cassette (about $25 at Performance, house brand)? I think
ideally I'd like to put on a road triple (52/42/30) so at least he
would be on the 14t (same ratio) on the large chainring. Is there any
down side or peculiarities to putting a road triple on a mountain bike?
Chainline, BB spindle weirdness, or maybe even front derailleur?
His current BB is square taper, and he never goes off road with this
bike. And he does practice good chain hygiene, pretty diligent about
soaking chain in kerosene as soon as he sees dirt on them. I'm
thinking the Sugino XD500 should be pretty good cranksets for him.
