Re:
Went for a ride on my road bike today after doing some upgrades/alterations. Dropped the big ring from 52 to 50, also changed cassette. The cassette was 9 speed and I'd rebuilt it last year by adding a 30 sprocket after dismantling it to re-arrange/change most of them to give ma auld legs a better chance of getting up 12+% hills. Found out that the brifters which are Ultegra 6600, are 2x10 speed but had indexed fine with the 9 speed cassette but with an extra click at bottom end of cassette. Duh, should have dawned on me way sooner. :facepalm:
So needed a new 10 speed cassette so got a 11-32, taking the chance the Ultegra 6600 short cage rear mech might not work over this range, think it's maximum sprocket is 27 with a total capacity of 29, front and rear difference combined, but it had worked fine with the 30 tooth and a total capacity of 32 with the 38-52 chainrings. Needed a new big ring anyway so got the 50 in an attempt at reducing the total capacity since I was adding 4 teeth over the maximum it's supposed to work with, it's now 33. A wee tweek of B-tension screw to move top pulley away from 32 sprocket and end stops to take in to account the wider cassette and it was indexing fine. There's still movement in cage when in big/big gears, not much but shouldn't be running in those gears for any length of time only by accident really.
Rides great, easier up hills but what about the 12% you ask, well it's definitely a tad easier but the final limiting factor is ME , bollocks, I'm too auld tae play this game. :roll:
