CUBE Reaction SLX – Premium Performance, Proven Platform
The CUBE Reaction SLX represents the sweet spot where premium components meet accessible pricing. Built on CUBE’s refined Reaction frame and equipped with Shimano’s revered XT groupset, this hardtail mountain bike delivers race-level performance for riders who appreciate quality but don’t need to prove it with a flashy price tag.
Why the SLX Makes Sense
Sometimes the best bike isn’t the most expensive one – it’s the one that gives you exactly what you need without compromise. The Reaction SLX achieves this by combining CUBE’s proven frame design with carefully selected premium components where they matter most: the drivetrain and brakes.
Shimano XT – The Benchmark Drivetrain
Shimano XT has been the benchmark for mountain bike drivetrains for decades, and for good reason:
Shimano XT 1×12 Drivetrain:
- Shimano XT RD-M8100-SGS rear derailleur – ShadowPlus technology for quiet, chain-slap-free performance
- Shimano XT SL-M8100-IR shifters – Direct attach, instant response, legendary reliability
- Shimano Deore CS-M6100 cassette – 10-51T range (510% gear range) for any terrain
- Shimano FC-MT511 crankset – 32T chainring, Boost spacing
- KMC X12 chain – Smooth, durable 12-speed operation
Shimano XT Brakes – Control That Inspires Confidence
Upgrading to Shimano XT BR-M8100 hydraulic disc brakes isn’t just about stopping power – it’s about control, modulation, and consistency:
- Post/Flat Mount – 180mm front, 160mm rear rotors
- Superior modulation – Feel exactly how much braking force you’re applying
- Powerful yet controllable – Strong enough for steep descents, smooth enough for technical sections
- All-weather reliability – Consistent performance in wet, muddy, or dusty conditions
- Easy maintenance – Tool-free reach adjustment, proven reliability
The difference between good brakes and great brakes isn’t just confidence – it’s the ability to ride faster and have more fun because you trust your ability to scrub speed exactly when and where you need to.
RockShox Recon Silver RL – Adjustable Performance
The RockShox Recon Silver RL Air fork with 100mm travel brings suspension sophistication to the Reaction platform:
- Air spring – Easy adjustment for different rider weights and terrain
- RL (Remote Lockout) – OneLoc handlebar remote for instant fork lockout
- 100mm travel – Perfect balance for XC and light trail riding
- Proven reliability – RockShox engineering and support
- Tapered steerer – Precision steering and robust construction
The remote lockout is a game-changer for mixed terrain rides – lock it out for efficient climbing on fireroads, then unlock it with a flick of your thumb when the singletrack starts.
