So I've been searching for the best option to get a lower gear range for touring on my cyclocross bike.
I was thinking, if its possible, maybe finding a cheap pair of shimano lx or xr cranks, and trading out my compact crankset, to get the smaller chain rings.
I currently have a 105 front derailleur, so i was wondering if it would work to get a shimano crankset with say a 22/32/44 chain ring combo and taking off the big ring, and just using the 32 and 22. Would it be possible to use the 105 derailleur with that set up?
EDIT: Or what about getting a road triple, and taking off the big ring, and changing the smallest ring for something a little smaller. and using the 105 FD i already have?
