SRAM has just released details of X7, it's latest groupset to use the 2x10 setup first seen on XX.
Features include X-Glide front shifting, Exact Actuation, new PowerGlide cassette ratios, carbon cage rear derailleurs, new S1400 crank offering and Avid Elixir R brakes.
With a more affordable price tag (we can presume, having not actually seen the UK price yet) SRAM is pitching this new groupset at mid-level XC to entry level downhillers and freeriders.
What does this mean for XO? I guess we'll have to wait and see...
