Cube Reaction C:62 SLX 29 2025 Bike

There's a purity of purpose in the Reaction C:62 SLX's clean aesthetics and light, agile C:62 carbon frame. It's made to do one thing - and one thing only - exceptionally well. And that is to travel as quickly as possible from A to B, cross-country, with you on board. Are you ready for this?

A seriously rapid bike demands serious components in the pursuit of speed. That's the reason that, for the Reaction C:62 SLX, we began by selecting a Fox Float 32 Performance SC fork - to help you keep the rubber side down and pointing where you want it. Sram's GX Eagle Transmission 1x12 gears serve up the huge range and crisp, accurate shifts you'd expect. A Newmen Beskar 3 wheelset shod with Schwalbe's Racing Ray and Racing Ralph 2.25in tyres delivers rapid acceleration and all the grip that you need. And, last but by no means least, Magura MT8 Pro hydraulic disc brakes give you the power you need to brake harder, later, and stay on the gas for longer.

There's a good reason for the Reaction C:62's beautifully organic lines and slender stays: it makes for an exceptionally fast, light frame. Our premium C:62 carbon and Advanced Twin Mold manufacturing is just the start. There's an integrated seat clamp, for secure fastening and the neatest possible appearance. Semi-integrated cable routing complements the frame's clean aesthetic and reduces the need for maintenance. UDH means it's future-proof, while Agile Ride Geometry does exactly what you'd expect, delivering safe but responsive handling. And, with a wide range of sizes from S to XXL, there's one to suit practically any rider.

Features

Not all carbon is created equal. With our C:62 carbon we increased the high modulus fibre content, then we reinforced the resulting material with nanoparticles incorporated into the bonding resin. Which is all just a fancy way of saying it's extremely strong, light and durable.

Our Integrated Seatpost Clamp is all part of our quest to sweat the details, so that you can reap the rewards. Its minimalist design suits the frame's pared-back aesthetic. And, of course, that's important - because why wouldn't you want your bike to look great? But it also saves a few grammes too. And that matters just as much...

A wider hub makes a stiffer wheel, and a stiffer wheel means better handling. That's the thinking behind the Boost 148 rear hub standard, which allows wider flange spacing for better wheel performance without impacting on shifting accuracy or drivetrain efficiency. Simply put, you can go faster and harder with better handling and stronger wheels.

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.

For off-road riding you need a bike that responds quickly, but also feels stable and secure. That's where Agile Ride Geometry comes in. Offering an ideal blend of on-demand steering precision, climbing agility and descending stability, it's perfect for every rider who values their time on the trail. If you're a mountain biker, you'll instantly feel at home...

A dropper post is a great accessory for adventurous riding, adding confidence and control on steep descents. Our Dropper Post Ready bikes are all set for this worthwhile upgrade, because they include internal cable routing for the remote lever that controls the seatpost. Once installed, you'll forget it's there... until you need it.

With our Advanced Twin Mold process we use two precisely manufactured forms for our C:62, C:68 and C:68X carbon frames. The first form is to ensure an accurate layup. The second, inner form keeps every individual fibre precisely where it needs to be while the frame cures. The result is a significantly lighter, stronger frame, with fibre density tailored to anticipated loadings at specific points.
