I always enjoy reading suggestions from others who share my passion for cog-by-cog and ring-by-ring custom gearing.

I also like the barcon suggestion -- I am delighted with the classic non-indexed ratcheting SunTours I put on my Peugeot workhorse, which has a customized half-step 12-speed transmission with 6-7% ratiometric progression from 43.6 gear-inch bottom to 93.5 gear-inch top. For longer and/or steeper hill work I would be inclined to keep the same top gear and spacing, but to add one or more larger cogs to the rear axle, which is currently only 122mm OLD (with ultra-6 freewheel). A good triple or a 110mm BCD crankset with a 34-tooth inner ring would be other sensible options.
