At 100 rpm that's well over 30 mph- if I'm descending that fast, it's time to coast and get some rest. Come to think of it, I did road races and crits with a 48 x 11 top gear. I didn't do any worse than I did when I had a 53 x 12. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
