Hi Electictracer, Thank you! I'm glad to help others as I have helped by others here. This a great forum full of very smart and accomplished people who also are very generous in sharing their knowledge and experience.
Do you have an electric vehicle or an eclectic one?
Are you going to ride in the Northwest Vetter Challenge on 6/1/2012?
Still raining here so further testing is postponed for a few more days. I talked with Alan Smith about the gearing and he has 39 and 37 tooth sprockets to try out.
Sendler, I used the GearCommander to check the effect the 33T rear would have and appears it may be feasible ( 6500@70 mph) , particularly if I can reduce the aero drag enough to allow decent acceleration.
best wishes L&S
