I'm currently running my Superlight 29 with 1x9, with a 30t hope narrow/wide, and an 11-34 xt cassette.
It's fine for an hours ride on my local trails, but over an hour the grinding uphill really takes it's toll. I live in a hilly area on the outskirts of the Peak District, so i need some lower gears or bigger legs!
Question is, should I put a front mech on my bike, and run a granny ring (I have an X0 shifter and my old triple chainrings, all i need is a mech and a bashring/single ring fixings - don't want a big ring)? Or stick with the 1x9 and hope i get strong enough to push the gear all day?
I could upgrade to 1x10, but to get XT level its going to cost close to £200... Also, I'm running Sram X0 shifters and rear mech at the min, which I think are rather nice.
Anyone else think its a shame no one makes a 9 speed 40t cassette adapter?
