Nukeproof Reactor 290 Carbon Mountain Bike Frame
Description
This frame is the perfect platform from which to build up your dream aggressive high-performance trail bike. Built around a full UD woven carbon fibre frameset, it’s as at home on the most technical trails as it is on technical descents, and will guide you down the most challenging routes with ease. These capabilities are thanks to the frame’s hydro-formed tube set and carbon seat stays, which help to ensure consistent handling with a low unsprung weight. This low weight also makes the suspension as active as possible, smoothing out the roughest routes so you can maintain speed and control. 4 Bar Horst Linkage Rear Suspension In addition to a low overall frame weight, the Reactor 290 frame has a 4 bar horst linkage back end. This gives increased anti-squat for when you’re riding in the climbing gears to attack a climb and lower anti-squat for putting the power down. This means your custom rig will not only climb efficiently, it will become a trail hooligan on the way down! Plus, the combination of low anti-squat and progressive rate provides outstanding small bump compliance to remove trail chatter, great mid-stroke support for cornering/pumping and end stroke progression for aggressive riding. Nukeproof’s extensive testing has found that this frame's anti-rise figures allow it some squat when braking hard, maintaining your riding position and giving the ideal amount of pressure through the tyre, to ensure traction. Adjustable Frame Geometry To give you the edge on the most challenging trails, you can also adjust the geometry of this frame to suit your riding style and the trails your ride. This is as the Reactor features “flip-chip” adjustment on the rear linkage. The “Trail” mode, as the name suggests, is best for trail riding, giving you the perfect balance of a steeper head and seat angle for maximum pedalling efficiency and still ideal position for descending at pace. The “Rail” setting turns your ride into a real corner shredder, by dropping the bottom bracket by 6mm and the head angle by half a degree, maximising this frame's descending capabilities.
