My daily commuter currently has a Sturmey Archer AW3. If you're familiar with these hubs you'll know the first gear can be very troublesome. Mine is no exception. My 2nd and 3rd work perfectly, and I am willing to live with just two gears. However, my commute is very hilly and is also fairly stop-and-go. Therefore I need a low gear!
Right now, I have a 47t front and an 18t rear, and I was thinking of getting a bigger rear so that my 2nd and 3rd gears become '1st' and '2nd' gears. Does anyone have a good suggestion on what size to get? I'd like to approximate the real -25% 1st, and 1:1 2nd.
