Instead of buying a new bike this year, I've been upgrading my 2010 enduro comp. It came with a shimano/sram 2x9 drivetrain which shifts like a dream. I am not exaggerating when i say I have never missed a shift with this setup. According to the internet i could shed a good amount of weight by swithchng to X0 and I particularly like the silver ones. One thing about the Shimano crankset that annoyed me was the big gap in pedal RPM's when dropping to the granny (22t) leaving me spinning my brains out and losing precious climbing momentum.
The X0 triple has a 22/33/?? that i think would work how I want using the middle ring most often and the small ring for the bailout.
Is a 2X crankset simply a triple with the large ring removed? Is the spacing the same width as a purpose made double?
Would an X0 triple function good as a double by replacing the large chainring with the plastic bash/chain guide ring?
And just in case people don't get what I 'm trying to accomplish, I pretty much never use my highest gears anyway.
