Suspension set-up is absolutely critical to a DH bike's performance, which is why we selected Fox's race-proven 40 Float Factory Grip X2 fork and Float X2 Factory air shock for the TWO15 SLX. Simple to set up and easily tunable to match rider preferences and track conditions, they're the heart of this gravity attack machine – and, combined with the frame's adjustable geometry and progression, your guarantee of a perfectly tailored set-up. Sram's precise-shifting GX DH gears provide motive power, driving a Newmen Beskar 30 wheelset shod with 2.5in Schwalbe Magic Mary and Tacky Chan tyres. And Sram's powerful Maven Silver hydraulic disc brakes ensure you've always got the means to rein your speed back in.There's a simple equation to explain how gravity acts on an object, but the TWO15 is designed to ditch the math in favour of pure speed... because out on the trail, that's all that really matters. We used our High Performance Aluminium to build a frame that's highly rider-configurable – so you can adjust head angle, reach, bottom bracket horizontal position and progression, according to taste. There's a fork bumper that doubles up as a cable port, and a future-proof UDH dropout at the rear. The high-pivot swing arm with idler pulley helps create a suspension feel that's as plush and progressive as you need it to be, and a mullet wheel set-up seals the deal. F=mg. Let's ride!
