Thanks.
Sheldons calcuator gives me 72GI for 46/17 on 28-622 and 165mm cranks.
48/19 would be 67GI
42/17 would be 66GI
44/17 would be 69GI
so maybe 42/17?
I'm not too keen on changing the sprocket for one with even numbers of teeth, and would like to change only one component of the drivetrain.
re rearbrake:
The problem is not slowing down, it's accelerating. If I have to use more force to accelerate, I'm more likely to loose control (or so I think)
