The Primer is Chromag's most progressive 29" bike to date. Chromag designed the Primer with the shortest stays possible. A lower than ever BB height with a slack head angle and steep seattube that let this steel hardtail dominate aggressive all mountain riding. Although this 29er will descend like no other, it still climbs as well as anything Chromag has built before. A redesigned ‘Yokel' junction maximizes the chainstay clearance making the Primer compatible with 27.5+ wheels and tire sizes up to 3.0" wide. This added versatility means the Primer is ready to tackle an even wider variety of terrain.
Jenson pairs the capable Primer with SRAM's all new GX Eagle drivetrain. GX Eagle brings SRAM's 12 speed technology down to a price conscience level that will have the masses jumping for joy. The all new GX cranks are lightweight and stiff, efficiently transferring your efforts to the wheel, driving you forward with authority. The GX shifter provides snappy and precise shifts across the 10-50t Eagle cassette, giving you plenty of gear range to charge the straights, and spin your way up the climbs. When it comes time to slow down, the Shimano SLX brakes deliver predictable power with the ability to stop you on a dime in any condition. The Rock Shox Pike RC fork ups the suspension game with ultra-plush and smooth, terrain gobbling action, and external rebound and compression adjustment. Jenson rounds out the Primer GX Eagle build with Industry Nine Enduro S 29" wheels wrapped with Continental X-King tires, and cockpit by Chromag and Race Face. So whether you are out on a casual trail ride or pushing your limits at the mountainbike park, this well-equipped Chromag is game.
