Cube Reaction TM One 2027
There's more than one way to get down a tough trail, and the Reaction TM proves the point. With a 65° head angle, 73.5° seat tube angle and a low standover, it's designed to be stable and reassuring when the trail is throwing questions at you and you're not sure of the answer. Short chainstays tuck the rear wheel under the rider for tight handling and superior traction, and there's plenty of clearance to run tyres up to 2.5in. Stealth dropper routing is standard, of course, as is a UDH hanger for future-proof gearing. And we included a durable moulded chainstay protector for quiet descents, plus an ISCG chain guide to keep everything on track.

TRAIL TOUGH FUN
Built for fun and safe control on even challenging trails, the Reaction TM Pro has your back – and the progressive frame geometry is just the start. A RockShox Psylo Silver 35 air fork serves up 140mm of root- and boulder-swallowing travel. Strong Newmen Performance 30 wheels are shod with Continental Kryptotal 2.4in tyres, so you can keep the rubber side down and pointing in the right direction. Powerful Shimano hydraulic disc brakes feature a 203mm rotor up front, for better stopping power even in tricky conditions. And Sram's Eagle 90 Transmission 1x12 gears enable flawless shifts, time after time. Add the remote dropper post, and it's the complete trail package.

DETAILS
Wearing its aluminium underpinnings proudly, the Reaction TM Pro's raw'n'black colour scheme shows off the attention to detail that's gone into its frame. Long, low, lean and fully equipped to tackle the rowdiest of line choices, it's got everything you need to take on the trail and win, every time.
