Ready for racing, this enduro-focused mountain bike (MTB) frame comes equipped with a hydroformed and triple-butted 6061-T6 aluminium build for the best balance of strength, durability and performance. Keeping your ride under control as you race across demanding terrain conditions. Another highlight is its race-ready geometry with internal cable routing, which provides smooth handling as well as a clean, sleek appearance. Coming complete with 148x12mm Boost rear hub spacing, this model is a great choice of upgrade for modern racing and for completing your enduro bike build. For over 12 years, Nukeproof's best-selling model; the Mega has been racking up awards on enduro stages and in the press around the world. With four Enduro World Series titles to its name, the Mega has become an icon that is synonymous with racing. Since 2009 the Nukeproof Mega has been on a constant development to meet the demands of Nukeproof's riders and customers alike. As a result, the Mega Alloy V4 frame is available for 27.5”, 29” or new Mixed (Front 29”/Rear 27.5” wheel sizes) wheel set ups, with each frame design tailored around each wheel size. Triple-Butted Alloy Enduro MTB Frame To optimise the strength and weight, the Mega is constructed fully out of T6061-T6 Aluminium including all forged parts. After winning four Enduro World Series Titles in three years the V4 design is an evolution of Nukeproof's ultimate enduro bike. At the heart of the frame is the brand's revised suspension Kinematic, designed to be more subtle off the top, whilst remaining progressive and predictable. Anti-Squat is used to create an effective pedalling bike that can be thrashed through technical terrain. The useable SAG range is also widened to allow riders to tune the suspension to the trails. Other key features include: · All new Aluminium chassis · Designed and improved suspension kinematics · All new geometry · Optimised sizing/fit – Medium to XXL · SRAM UDH · Now fits a 750ml water bottle inside the main front triangle! The Mega frame is optimised around the rider and weight distribution. The geometry features dynamic saddle offset. Seat angles are optimised for each frame size and the seat tube itself is designed to take a longer dropper post if required.

With a 130mm fork combined with 125mm of rear suspension, the Reactor ST combines the best of an enduro bike (long, low and slack) with the best of an XC Race bike (lightweight spec and efficient suspension) to create a sprightly yet seriously capable machine. Frame Construction: To optimise the weight, strength and stiffness, the Reactor 290 ST Carbon frame features a full UD woven carbon fibre frameset (Including chain and seat stays). Adjustable Geometry: The Reactor ST features a 66.8° (66.3° Low) Headangle atop a 76.3° (75.8° Low) seat angle across a 460mm reach on a Medium frame. We also offer the frame in Large and X-Large sizes. The Reactor ST frames feature the same “flip chip” design as the regular Reactor frame to adjust the geometry from “Trail” to “Rail mode”. Trail – As the name suggests, this setting is best suited for trail riding. It is for riders who get as much enjoyment from the climb as the descents. Rail - The Rail setting turns the Reactor ST into a more aggressive machine, dropping the bottom bracket 6mm and slackening the head angle by half a degree. It is there to maximise the descending capabilities. Suspension Design: To ensure the bike could climb as well as it descends, we designed the four-bar horst linkage to have higher levels of anti-squat for climbing gears but lower levels when you drop down the cassette. This means that the bike can behave itself on the climbs but when you get it up to speed, it turns into a trail hooligan. The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor ST some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor ST is designed to reward the rider and ensure you get that stoke factor in on any ride.
