I humbly ask your advice. My crank arm is jacked up (long embarrassing story) and needs to be replaced and I found a good deal on a compact.
What parts would be required to switch from a triple to compact crank? What would have to be done to the front shifters?
The triple is the stock bontrager select and the compact is a shimano ultegra on a trek 1200. Everything is pretty much stock on the Trek.
What would make the most sense: order a new identical crank, replace with a compact, or replace the crank arm with spare parts from a LBS?
