Chromag Rootdown Ba SLX Jenson Bike 2017

Chromag Rootdown B.A. SLX Jenson Bike 2017

The Chromag Rootdown defys the narrow definition of what an All-Mountain hardtail should be. They are not just for old-timers and cross country racers. The Rootdown is a modern trail hardtail made to handle all types of mountain biking; it is able to descend any trail that lays before it with maximum speed and stability. It will steamroll roots and mash through rocks, while remaining a capable climber. The Rootdown will leave you with a huge smile, and will become your go to bike for every ride.

In 2016, Chromag updated the Rootdown frame with a combination of longer top tube, shorter chain stay, slacker head angle, steeper seat tube, and lower BB. It embodies a significant progression for the all mountain hardtail. The new 2017 version continues that legacy further with the additional clearance needed for 27.5+ tire compatibility. Built with Chromag’s custom-drawn tubes and featuring a 12 x 148 Boost rear end and stealth post routing. This is the evolution of Chromag frame design in 29er form, compatible with 27.5+ tires. It's an agile ascender and a dominant descender that is ready for anything.

The Custom Collection Jenson build pairs the Rootdown frame with trustworthy Shimano components. Shimano SLX 11-speed shifter and derailleur smoothly move the chain across the 11-speed Shimano XT cassette, and with the 11-46T gear range, you are supplied ample gearing to spin your way up steep climbs and mash down fast descents. When it comes time to slow things down, Shimano XT hydraulic disc brakes will get you stopped on a dime without sacrificing control. 140mm of plush travel from the Rock Shox Pike RC fork lets you confidently plow through rock gardens while managing to stay compliant through the smaller stuff. Race Face Aeffect wheels roll fast and smooth, with Schwalbe Nobby Nic 27.5 x 2.6" tires supplying the traction needed to rail corners. A Race Face Aeffect bar and stem round out this capable build that is sure to impress.
