Reaction TM PRO Mountain Bike 2027 Hardtail MTB

The Cube Reaction TM Pro is a capable trail hardtail with progressive geometry, a 140mm RockShox air fork and SRAM Eagle 90 Transmission. Four-piston Shimano brakes, wide Continental tyres and a dropper post add control on technical terrain.Key Features:Aluminium Lite frame with Trail Motion Geometry, Boost 148 and UDHRockShox Psylo Silver RC Air fork with 140mm travelSRAM Eagle 90 Transmission 1x12 drivetrain with 10-52T cassetteShimano BR-MT520 hydraulic disc brakes with 203/180mm rotorsNewmen Performance 30 wheels with 2.4in Continental Kryptotal tyresHandlebar-operated Cube dropper post for easier movement on descentsAvailable with 0% APR financeThe Cube Reaction TM Pro takes the simplicity of a hardtail and gives it a more trail-focused character. With progressive Trail Motion Geometry, 140mm suspension, wide tyres and a dropper post, it's designed for riders who want to tackle more technical terrain without moving to a full-suspension bike.Cube builds the frame from Aluminium Lite using its Advanced Mechanical Forming process. Trail Motion Geometry gives the Reaction TM Pro its more aggressive trail focus, while a tapered head tube, Boost 148 rear end and 15x110mm Boost fork provide modern interfaces for the wheels and suspension.The frame also uses SRAM's Universal Derailleur Hanger (UDH), making replacement hangers easier to source. An ISCG05 interface provides provision for a compatible chain guide, while internal cable routing keeps the frame looking tidy.A RockShox Psylo Silver RC Air fork provides 140mm of travel. Its air spring can be adjusted to suit rider weight and setup preferences, while the longer travel is designed to provide additional control and impact absorption when riding rougher, steeper trails.SRAM Eagle 90 Transmission provides a 1x12 drivetrain. The direct-mount Eagle 90 Transmission rear derailleur is paired with an Eagle 90 shifter, 32T DUB chainset, Eagle 70 T-Type chain and wide-range XS-1270 10-52T cassette.The single-chainring setup keeps shifting straightforward, while the 10-52T cassette provides a broad spread of ratios. The large 52T sprocket gives an easier climbing gear for steep gradients, with the 10T smallest sprocket providing range for faster sections.Shimano BR-MT520 hydraulic disc brakes provide four-piston braking front and rear. A large 203mm front rotor is paired with a 180mm rear, giving the front brake additional leverage and heat capacity where much of the braking load is concentrated. This suits the Reaction TM Pro's more demanding trail intentions.Newmen Performance 30 wheels use 28 spokes front and rear, with a 15x110mm front and 12x148mm rear thru-axle setup. The rims are tubeless ready, and the supplied specification doesn't state the wheel diameter, so I've avoided assigning an unsupported 27.5in or 29in size.Continental Kryptotal tyres are fitted front and rear in a wide 2.4in size. Both use the Enduro Soft construction and are tubeless ready, but each end gets a position-specific tread pattern. The Kryptotal Front prioritises steering grip and control, while the Kryptotal Rear is designed around rear-wheel traction and braking.Because both the Newmen rims and Continental tyres are tubeless ready, the bike can be converted to tubeless without changing either. A tubeless setup can allow lower pressures for additional grip and comfort while sealant can deal with many smaller punctures.A Cube dropper post is fitted as standard and operated by a handlebar remote. Dropping the saddle out of the way gives the rider more room to move around the bike on steep or technical descents, before returning it to full height for efficient pedalling.Newmen also supplies the cockpit, with an Evolution 318.4 stem paired with a Beskar 318.40 handlebar featuring its VariGrip System. An ACID Venec Lite saddle completes the main contact points.At a stated 15.5kg, the Reaction TM Pro is less focused on cross-country efficiency than the regular Reaction models. Instead, its 140mm fork, progressive geometry, four-piston brakes, dropper post and 2.4in Kryptotal tyres create a hardtail better suited to riders who prioritise control and capability on more technical trails.
