How do you enhance the performance of an already exceptional bike equipped with quality parts? By upgrading to superior brakes. The Reaction SLX features Shimano XT hydraulic disc brakes that deliver strong, progressive stopping power, boosting both safety and speed on the trail. Paired with the RockShox Recon Silver air fork’s smooth responsiveness and the Shimano XT 1x12 drivetrain’s effortless shifting and wide gear range, this bike is ready for any adventure. Completing the package are the Schwalbe Racing Ralph 2.25in tires, offering a perfect balance of speed, grip, and smoothness for trail riding.
The Reaction’s streamlined design comes from smooth welded joints at the head tube and seat tube. It features a threaded bottom bracket and internal cable routing, along with a flat disc brake mount that integrates cleanly with the kickstand and dedicated mounting points for ACID mudguards and a carrier. Its trail-focused geometry includes a lowered top tube and a tapered head tube for improved handling confidence, with ample clearance for wide, grippy 2.25-inch tires. As your riding skills progress, there’s also the option to upgrade with a dropper post.
