The rear freewheel cassette is a Shimano MegaRange 13-34T with 7 gears. Oh, and I had forgotten that I had replaced the crankset last year as well. I don’t have the receipt in front of me to say how much that cost me but the original crankset only lasted me 4 years. I squeezed another year out of the bottom bracket before replacing it this year.
Most of my riding is commuting and bike trails. I do some long distance on those trails (80 mile days, Pgh to DC) but, at 2500 miles a year I’m not pounding the hell out of my machine.
