Nukeproof Reactor 275 Alloy Mountain Bike Frame (2020)

Custom Triple Butted Hydro-Formed Tube Set and Carbon Seat Stays

With a custom triple butted hydro-formed tube set and carbon seat stays at its core, this Reactor frame is engineered to provide the best strength and stiffness at low weight in this category. Fine-tuned for the best manoeuvrability, stability and control, this 27.5" alloy frame construction glides you across the roughest of terrains with trail-gobbling performance and confidence-inspiring reliability.

Flip Chip Adjustable Suspension Geometry

All models of the Reactor feature a "flip-chip", so that the bike geometry can be easily adjusted from "Trail" to "Rail" mode without having to custom tune your suspension setup. The Trail setting is best suited for pumping and carving your rhythm and style into the mountainside and still caters for rides who love the climb as much as the descent. On the other hand, the Rail setting turns the Reactor into an adrenaline-fuelled gravity tamer. Dropping the bottom bracket height by 6mm and slackening the head angle by half a degree, these changes give this Reactor greater stability and control when the trail leans downhill towards vertical.

Technologies:

Nukeproof 4-Bar Horst Linkage Suspension Design: Ensuring the bike can climb as well as it descends, Nukeproof focussed on fine-tuning their 4-Bar Horst linkage suspension set up to give higher levels of anti-squat performance when higher up the cassette in the climbing gears, but also to deliver greater trail-gobbling performance when you drop down the cassette and begin descending the mountain. This means that the bike behaves itself on the climbs and grips with unprecedented traction and efficiency when making your way back towards sea-level. When you get it up to speed and drop a few gears to carry momentum, this bike turns into a trail hooligan and helps you carve the trail with style. The combination of low anti-squat and progressive suspension-rate give it the ultimate in small bump compliance (removes rough trail and root chatter) with good mid-stroke support for cornering/pumping and end stroke progression for aggressive riding. With balanced anti-rise suspension performance, the Reactor provides some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure stability and traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.
