Because 20/22 is a lot less than 40/32, and I want a LOW lowest gear for steep dirt hillclimbing.
Also, the following is secondary and wasn’t thought of in the design phase, but it’s a lot simpler shifting the front since the bike has no derailleur hanger. That cable-less derailleur as shown would not be in the optimum spot if it had a cable and were used as a shifter. But as a tensioner, it’s just fine. > On Feb 7, 2019, at 8:56 AM, Patrick Moore <bertin...@gmail.com> wrote: > > James: Why 3 rings, fd and rd instead of 3 cogs and rd, particularly since a > tooth in the rear gives more difference than a tooth in the front?
