Reactor Alloy 290

The Reactor Alloy is built around geometry that balances agility, stability and all day efficiency. A long, low and slack stance adds confidence on descents, while a steep seat tube angle places the rider centrally for precise handling and efficient power transfer on climbs. The four bar Horst Link platform delivers 140 mm of rear travel and is tuned to be supple off the top for traction and comfort, with strong mid stroke support that keeps the bike lively and responsive in technical terrain. As speed increases and you move down the cassette, anti squat reduces so the Reactor stays composed through rough sections and under braking, maintaining control and grip when it matters most. Combined with adaptable geometry via the Trail or Rail flip chip, the Reactor can shift from a nimble trail climber to a planted, confidence inspiring descender, a true all rounder ready to thrive wherever the trail leads.

The Reactor Alloy balances toughness, precision and performance. It uses a 6061 T6 aluminium front triangle and chainstays for strength and reliability in aggressive trail riding, with a carbon fibre seatstay to fine tune responsiveness and vertical compliance. This hybrid layout gives a lively yet controlled feel on the trail, stiff and direct when pushing hard and smooth over rough terrain. Tubes and junctions are optimised for strength to weight, so the frame feels solid and dependable without losing agility. Built for everything from long mountain days to bike park laps, the Reactor Alloy combines practicality and performance for riders who demand versatility and durability in a single package. Adaptability is central to the design. A two position “Trail or Rail” flip chip lets riders refine geometry and handling. Trail mode provides an efficient balanced feel for big days, while Rail mode lowers the bottom bracket and relaxes the head angle for more aggressive descending and corner support. The Reactor V2 also offers wheel configuration options. The 290 Trail or Rail chip in the rear triangle can be switched to a 297 mix wheel Rail chip. Geometry and suspension kinematics match the 29 inch Rail setting, ensuring consistent performance across setups.
