So that bike is good for speeds in between 7MPH and 22MPH. The book "Effective Cycling" recommended that you target 100rpm because traffic, scenery, and other distractions would cause your cadence to drop to around 80-90 in practice. On the tandem with the 9 year old, we've gone as high as 130rpm because our top gear is 38x11 and occasionally need to stay in a draft with a fast group on level ground. My top speed ever on a tandem was 65mph. But we didn't need to pedal at that speed. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
