Pretty close to settled spec, now on it's 4th drivetrain setup, running a 10sp. e13 175mm DH Cranks & LG1+/XT Shadow+ with 32x11-36 gearing. Answer's 60mm stem and 720 Carbon bar, SGD Bel-Air, and Specialized CP Blacklite round out the cockpit. Avid Elixir 5's with 185mm rotors stop this 29lb trailbike just fine. Speshy Butcher 2.3SX and Conti TrailKing 2.2 rolling on Mavic Crossline wheels pretty much finish her out.
