I have an old 80's MesaRunner with horizontal drops and I'm going to put an internal hub on it. I have been using it as a singlespeed commuter but I want a tad more gear range to save my knees in 30 MPH headwinds.
What's a good choice? I do not want coaster brakes-- unless someone can change my mind. Are three speed hubs more efficient than say a 7? How much more does a 7 speed weigh than a 3?
Thanks in advance.
