Plan on loaded touring next year. I have a Schwinn Paramount steel frame that has been modified for touring. I will be using 700c x 28 wheels. I intend to replace the double crankset with a mountain bike triple. My question, should I install a 22-32-44 or a 26-36-48? My cassette is an 11-32 that I plan to change to 11-34. I have Shimano Deore XT M732 derailleurs.
