So I thought I'd give this 1x10 malarkey a shot - I 'felt' it would suit the way I ride my bike, I desperately wanted a clutch rear mech, and I'm a sucker for new ideas....
Was already running 2x9 (36/26, and 11-32 cassette) and opted for 34t chainring, and 11-36 cassette.
Old low gear was 0.8125, new is 0.94444..
Old top gear was 3.272, new is 3.09090909...
In English - I've lost the bottom two (nearly) gears I did have, and have lost 'a tooth' on the top gear (as if I were to have a 12t small sprocket on the cassette..)
But...here's where it gets reeeeeal geeky!
What came off:
What went on:
So... weight coming off = 1101g
Weight going back on = 762g.
The astute amongst you, and those with calculators, would have equated the difference as being 339g. Or a muddy can of coke. Or 0.74lb.
In terms of cost, that's practically impossible to tell, so shan't even consider figuring that one out...(or if the wife's not looking, about £155 on the 10sp stuff, and in the process of selling the 9sp stuff for £80-100).
However, the bike is now beautifully silent - and TBH I blat around most of my trails on the SS anyway ([numbers]which is a gear ratio of 2[/numbers]) so losing a few 'sissy gears' isn't too bad.
The clutch mech really is a neat bit of machinery, and with the thick-thin chainring I haven't dropped a chain yet...
So, there you go, hope you had your numbers fix for this evening...
