Check the bottom bracket for a letter stamped in the housing; I believe a 'C' is the Dynamic Street ratio and a 'B' is Sport.


Check out this page as it shows the different ratios: http://www.sussex.com.tw/se2.htm

My Crossroad 8 shipped with a C shaft, which I believe was the 2.07 ratio. I replaced that with the Sport shaft stamped with a B, which I believe is a 1.77 ratio. It was a big help climbing my 10% grade hill at the end of my commute home at the end of my day.

My big challenge right now is to convert my bottom bracket from grease to an oil bath and keep the oil from leaking out. Since I switched to oil bath lubrication I have had no problems with lubrication, grinding noises, etcetera. Changing to oil bath has solved what is to me the biggest complaint about this drivetrain. Now I just gotta keep the oil on the inside...
