Overview
Mountain Bike Cube Reaction SLX
The Reaction's sleek looks are thanks to its Smooth Welded head tube and seat tube junctions. It incorporates a threaded bottom bracket and Internal Cable Routing, plus a flat disc mount that integrates seamlessly with our kickstand mount and integrated mounting points for ACID mudguards and carrier. Trail-ready geometry includes a lower top tube and tapered head tube for more confident handling, and there's plenty of room to run wide, grippy and comfortable 2.25in tyres. And, as your skills increase, there's scope to fit a dropper post upgrade.
What do you do to improve the ride of a great bike that already features great components? You fit better brakes. The Reaction SLX's Shimano XT hydraulic disc brakes' powerful, progressive control doesn't just help keep you safe, it also helps you ride faster and have more fun. Combined with the smooth control of the RockShox Recon Silver air fork and easy shifting and huge range of the Shimano XT 1x12 gears, you're pretty much all set. The Schwalbe Racing Ralph 2.25in tyres – fast-rolling, smooth and grippy – round out the complete trail exploring package.
Technologies
There's aluminium, and then there's CUBE Aluminium Lite. This heat-treated 6061 aluminium is stiff, fatigue-resistant and, because of its natural corrosion resistance, a great material from which to make lightweight tube sets – and bicycle frames. And it does all this without adding unnecessary weight, so you can get the best enjoyment out of your CUBE.
Cables connect your handlebar controls to vital components like gears and brakes, but there's no need for them to get in your way. With Internal Cable Routing we've reduced clutter and maintenance by running cables through the frame, keeping them out of the way of dust and water contamination – or damage from abrasion – as well as cleaning up your bike's appearance.
A kickstand can be useful, no two ways about it. But if it's going to do its job properly, it needs a secure mount. That's why we put as much effort into designing the Kickstand Mount for our frames as we do for any other feature. Neat, unobtrusive but exceptionally strong and stable, it's the best way to help keep your CUBE bike upright when you're not riding it.
Flexibility is important for a bike that's going to slot into your life. That's why, for our Semi Integrated Carrier Mount, we designed a system that's unobtrusive when you don't need it and really simple to use when you do. By adding our Semi-Integrated Carrier your CUBE can take on the shopping, your commute, or take you further afield at the weekend…
Smooth Welding isn't easy, but worthwhile things usually aren't. It has two advantages. First, and most obviously, it looks great: one tube seems to almost flow into the other. Second, and at least as importantly, it helps to minimise load peaks on welded areas for better frame strength and durability.
