I have a Surly LHT touring bike that I built this spring, mainly used for
commuting, but I plan to do some self-supported touring. Unfortunately,
beginner's mistake, I geared it too high with 105 triple crank, and 12-26
road cassette (9 speed) and 105 rear der.
First question, how big can a 105 triple rear derailleur handle? Can it go
mountain-type cassettes like an 11-32? My guess is probably not.
Second question, can I buy smaller chain rings for the 105 triple crank, or
should I just buy a Sugino touring crank and BB and be done with it?
Third question, I'm using DuraAce bar end shifters. If I use LX or XT
shifters (if I have to), is there a problem with compatibility?
My logic is, replace the crank with something like a Sugino 48/38/28 (if
anyone has suggestions for others), change to an LX mtn rear derailleur (or
maybe a SRAM?), and use a mtn cassette of my choosing. Leave the bar end
shifters and front derailleur the same.
I also don't know whether a ratio like a 28 or 26 small ring / 32 rear cog
is too low to be useful, but truth is I haven't loaded it up yet.
BTW - if anyone in the USA wants to make some sort of trade, email me (take
the Z's out). I also have a Centaur standard double with about 1000 miles
on it that I'd be willing to depart with...
Thanks in advance!
