The Merida Reacto has always been a class leading aero bike, combining state of the art aerodynamics with rider comfort. The 4th generation model is more slippery and beautiful than ever, incorporating wider tyres, much neater cockpit cable integration and a series of incremental improvements to boost performance. In the world of Pro-Tour racing no area can be ignored. Computational Fluid Dynamics (CFD) calculations were used to model performance in a virtual wind tunnel, guiding the changes which offered the most aerodynamic benefit: Prototypes were wind tunnel tested following the German TOUR magazine standard, including the ‘moving leg dummy’ test. The Reacto CF5 needs just 209 watts effort for 45 km/h speed, 1 watt faster than its predecessor so it's in the leading group of aero road bikes ever tested by TOUR magazine.Small details such as integrating the front disc cooler behind the fork and the rear disc caliper in the rear triangle and creating new bolt through axles with the thread integrated into the fork dropout minimise drag and improve aerodynamic performance. A myriad of small improvements over-compensate for the aerodynamic compromises made to give the Reacto bigger tyres, resulting in the perfect package of comfort, aerodynamic, lightweight and style. A long string of test wins, perfect scores and awards confirm the successful evolution of the race-proven DNA of the previous model with the latest trends and technologies. Cycling Weekly described it as 'without doubt one of the most complete bikes available on the market', Cyclingnews 'an utterly brilliant and faultless machine' and Cycling Plus were 'hugely impressed'. All Reacto come with powerful hydraulic disc brakes. Calipers are mounted on the chainstay for better dissipation of braking forces using the flat mount standard for a neat, flush fit. Calipers sit on top of CNC'd aluminium Disc Cooler fins which reduce operating temperatures by up to 35%.
Nukeproof Reactor 290 Pro Alloy Bike (GX Eagle)If you want to push yourself to the limit on the trails, the Reactor 290 Pro Alloy Bike is the ideal full suspension ride for you. Its advanced aluminium/carbon frame combines with the terrain smoothing performance of the RockShox Lyrik forks and a RockShox Super Deluxe rear shock. Plus, there’s also SRAM GX 12-Speed gears to give you the range for any riding situation.From concept through to design, the Kinematics, the geometry and specification; the Reactor is designed from the ground up to be the ultimate aggressive trail bike. It is at home on technical climbs, but happiest when thrashing the most technical trails you can point it at.Frame Construction:The Alloy Reactor features a custom triple butted hydro-formed tube set and carbon seat stays, which help reduce the overall weight of the frameset. Critically this reduces the unsprung weight; making the suspension as active as possible.The Reactor is available for 27.5” or 29” wheel sizes. These are two totally different, compromise-free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size.Speed or play: which do you value more? The manoeuvrability of 27.5” or the raw speed of a 29”?Adjustable Geometry:All Reactor frames feature a “flip chip” 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 into a corner shredder, 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 4 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 some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.Features: Frame: Nukeproof Reactor 290 Alloy, 130mm Travel, custom triple butted hydro-formed tube set for front triangle and chainstays, UD woven carbon fibre Seat stays, internal cable routing, internal cable routing, ISCG 05 mount, Enduro bearings, threaded 73mm BB, Boost 148mm rear axle spacing, 3D contoured rubber frame protection Fork: RockShox Lyrik Select + Charger 2.1 RC 150mm, 42mm Offset, BOOST, Debonair, Gloss Black Shock: RockShox Super Deluxe Select+ RT, Custom 320 tune, 210x50mm, Bearing End, 1x bottomless token fitted Front Wheel: Nukeproof Neutron V2 29", Tubeless Ready, 32h, 110x15mm Rear Wheel: Nukeproof Neutron V2 29", Tubeless Ready, 32h, SRAM XD Driver with 36 points of engagement, 148x12mm Tyres: Front: Maxxis Assegai 29x2.5" WT 3C MaxxTerra/EXO+/TR, Rear: Maxxis Dissector 29x2.4" WT 3C MaxxTerra/EXO+/TR Crankset: SRAM GX Eagle 12-Speed, 170mm, 30T, B148, DUB Shifter: SRAM GX Eagle 12-Speed Rear Derailleur: SRAM GX Eagle 12-Speed Chain: SRAM GX Eagle 12-Speed Cassette: SRAM GX Eagle 12-Speed, CS XG1275 EAGLE 10-52T Brakes: SRAM Guide RE Front Rotor: SRAM Centreline, 200mm Rear Rotor: SRAM Centreline, 180mm Handlebars: Nukeproof Horizon V2 25mm Rise, Width - M780mm, L800mm, XL800mm Stem: Nukeproof Neutron AM, 45mm, black Saddle: Nukeproof, Black Seatpost: Brand-X Ascend internal, 31.6mm, M:150mm drop; L: 170mm drop; XL:200mm drop Headset: Nukeproof, 44-56 IITS Grips: Nukeproof Sam Hill Signature Weight: 14.73kg (Medium, Tubeless) Please Note: Due to severe delays in the bicycle supply chain, Nukeproof has been forced to make some alterations to the specification of the component parts supplied with this bicycle.

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 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 setup 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.
