who the hell thinks that top speed on 42:16 is only 14 mph? spin faster, baby. 120 rpm or so!

i get up to 22-25 mph on that set up. lotsa big hills here (taipei), and the SS is my training bike, so it builds high cadence and hill climbing ability all in the one trip. plenty of gear for sprint starts at traffic lights, and not much chance to actually cruise along at any speed for any distance, so any higher is really not needed.

YMMV
