The aggressive frame angles of the Nemesis combined with a generous top tube length, delivers an ideal XC geometry. Pedaling and climbing are remarkably efficient. Handling is quick and nimble.
SPF FRAME TUBING
The alloy frame tubes on the Nemesis Comp and Sport are made by SuperPlastic Air Forming. SPF is carried out at high air temperatures, where the tube structure is in its most ?plastic? and formable state. This allows more complicated shapes to be produced that cannot be made using traditional forming techniques. For example, whereas shape designs can be applied to 25% of the tube using hydroforming, SPF allows up to 90% manipulation. The result: more optimized shapes and less weight.
Tapered Head Tube and Fork Steerer
Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. Moving to a full 1.5? head tube and steerer would achieve this, but would add unnecessary weight and bulk. Not to mention 1.5? steer clamp stem choices are limited. But a tapered 1 1/8? to 1.5? head tube and steerer serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1/8? systems since the steer tube wall thickness can be reduced.

TOP FIVE THINGS YOU NEED TO KNOW
Rock Shox’s XC30 TK fork offers 100mm of travel, 30mm stanchions, aluminum crown, preload, lockout and external rebound controls – all usable and functional “on-the-fly” adjustments that can be felt by the rider.
Shimano’s 40/30/22T chainwheel and 11-34T cassette supplies a wide range of usable gears.
Shimano M355 hydraulic brakes use non-toxic mineral oil that does not absorb water from the air reducing the chance of bubbles forming in the system.
Ritchey’s cockpit parts are manufactured by a 3D-forging process which optimizes grain structure and eliminates all internal imperfections, allowing Ritchey to use less material without sacrificing strength or durability.
The WTB Volt saddle utilizes a “whale tail” pad shape which helps increase power output by properly angling? the sit bones while climbing. A flex tuned shell and a Comfort Zone cut out below the nose increase comfort while riding on the front of the saddle.
