Hello Sneak Bird, I live in Salt Lake City so I know what hills you are talking about. I ride my Basso with a Campy NR RD and Campy 50-34 compact crankset with a Sachs 13-26 freewheel. I tried to use a 13-28 freewheel, but it did not work well for me with the NR RD. The RD pulley did not clear the 28 sprocket cleanly. I also moved my axle as far back as possible in the dropout. The combination of the compact crankset and 13-26 freewheel provides the gear range for any canyon climbs around here.
