new bling - a Shimano HG-500-10 cassette is now on my bike |
Since I went for super-short cranks, I have had a bit of a hill problem.
My 175mm cranks had a triple ring setup, and I used to run 48, 34, 26, along with my 11-32 SRAM PG850 cassette.
The 145mm cranks I switched to (MUCH easier on my ageing right knee) are only a "double) at 48, 34.
So my "crawling up a hill" gearing had gone from 26f/32r (= 0.8125) to 34f/32r (= 1.0625) - a rise in gearing of 30%
Hmm, I thought to myself.
I have friction shifters (so I don't have to worry about indexing), and a "long-cage" derailleur (a Shimano RD-591), so, maybe I just need a new cassette and chain, give everything else a clean up, fiddle with the b-screw, reset the High and Low stops on the derailleur, and job done?
Sort of ;-)
