Made my Giant CoMax 1 into an 11 speed.... Over the weekend the front 2 speed Shimano shift lever broke. So while I wait for a replacement part I had to take off the front 105 derailleur had to be taken off the bike to at least have the 58t crank wheel. Let that be a lesson to those that don't use all the gears. Mine broke because of lack or use. Oh well who needs a 22 speed bike in Florida anyway.
