Jamis Dakar Sixfifty B Pro 2012

Jamis is no stranger to the world of 650B. As one of the early adopters of the growing movement, Jamis has put in long hours of extensive research and development to ensure that their workhorse designs transfer effectively to the 27.5" / 650b platform. The Jamis Dakar Sixfifty B Pro 2012 is a stunning example of a trail bike that brilliantly bridges the gap between the 26" and 29" wheel platform. Confident obstacle clearance and snappy handling are merely two of the benefits of the Sixfifty B Pro, with many more nuances coming through in Jamis's signature mp4 suspension linkage and the Sixfifty Pro's exceptional build kit. Throw a leg over the Dakar Sixfifty B Pro and get a taste of the best of both worlds!

The Dakar Sixfifty B Pro 2012 features a lightweight Kinesium triple-butted alloy main triangle for excellent stability and durability that stands up to the abuse of trail riding without excessive weight. The Dakar Sixfifty B Pro utilizes Jamis's fully-active mp4 trail suspension design, which has been optimized for trail / all-mountain performance, with 130mm of travel to help tame the diverse terrain typical of trail riding. Suspension duties in the rear are handled by a Rock Shox Monarch RT3 that tames bumps and sudden shocks with precision. The Dakar XCR's plush front-end comes courtesy of the White Brothers Loop TCR 650B fork. The White Brothers Loop TCR 650B's 15mm thru-axle and tapered alloy steerer offer a rock-solid front end that refuses to quit so you can keep cranking on down the trail, dominating rock gardens and clearing sketchy terrain without issue. 

The Jamis Dakar Sixfifty B Pro build kit is a confidence-inspiring package that features tried and true industry favorites. The SRAM X0 39/26t crank is the power center of Sixfifty B Pro build. The SRAM X0 crank is paired with a matching XO 10-speed rear derailleur and an X9 front derailleur. Shifting is controlled effortlessly by a pair of SRAM X0 10-speed trigger shifters for crisp and responsive shifting that will keep you pedaling easily and transferring power efficiently. The Sixfifty B Pro rolls confidently on a set of American Classic 650B XC disc wheels wrapped in the grippy but fast Kenda Nevegal tires for a combination that offers an aggressive blend of strength and trailblazing speed. Avid X0 hydraulic disc brakes offer all the power you need to stop on a dime or modulate braking when navigating a tricky section, and a thoughtful pro cockpit featuring the WTB Volt Race saddle paired with a mix of Ritchey Pro handlebars, stem, and seatpost, ensures that your trail control center is decked out and ready to help you explore.
