The CUBE Reaction range is a well established and highly revered range of Hardtail mountain and electric bikes from German-based brand CUBE. With each bike that comes out of their factory rigorously checked at their in house laboratory, you can be sure that a lot of hard work and innovation is put in by the company in order to present the best possible bikes to the market. 2018 has seen a number of exciting new technological and geometrical developments within the Reaction range, ensuring that the Reaction will remain at the top-end of bikes within their class. This guide intends to give you a quick run through of what's new this year, for more detailed information visit one of our stores or contact us via phone or email.

Featured Technology

C:62 - Light and stiff in equal measure, CUBE'S C:62 frame material is made with a carbon content of 62%. The high carbon content is achieved during production by using three integrated techniques such as advanced Twin Mould - minimising imprecise overlaps by accurately fitting individual carbon layers' overlap regions during the monocoque building process. The result is a frame with no superfluous weight - every gram counts. CUBE also use a solid core in the centre of the frame during the manufacturing process, which is removed when the frame is finished. This reduces the build up of folded material and increases the safety and integrity of their frames. An extraordinary combination of materials is needed to make the best quality carbon. By using High Modulus fibres, CUBE have made the C:62 frame extremely stiff. Finely dispersed nanoparticles are integrated in the resin that bonds the two carbon layers and thanks to these tiny particles, the durability of the frame is improved - and it's also less sensitive to impacts and better able to withstand external forces.

CUBE High Performance Aluminium - To create as strong an aluminium frame as possible, CUBE have used a special alloy in combination with a hardening heat treatment. Triple or even quadruple butting of the raw aluminium allows them to use the minimum quantity of material, because wall thickness can be adjusted according to load. They also use specifically designed hydro-formed tube shapes. These production processes, combined with the use of CUBE'S wet paint process (logos and lettering on polished or brushed frames are protected by several layers of wet paint),results in the creation of stiff, high performance frames with unique looks. The proprietary Advanced Mechanical Forming process allows them to tweak tube characteristics without tedious and complex welding requirements. It's a manufacturing method that improves both appearance and function: Happy days!

Stealth Dropper Post - Dropper seat posts are posts that can be raised or lowered while riding with the push of a button. They've come a long way since the early days of spring powered,temperamental 'dropper' posts of the early 90s and are now regularly seen on the trails. Dropper posts allow you to have complete control of your saddle height allowing you to keep it high for efficient pedalling on the flat and move it lower for descents to move the saddle away from your delicate places.

Boost Rear End - A new drop-out standard that widens the hubs on your wheels, growing the front axle by 10mm and the rear axle by 6mm. This creates a wider bracing angle for the spokes which contributes to a stiff and strong wheel which is always a good thing!

Air Sprung Forks - Lighter than a coil sprung fork with a progressive compression rate and soft initial travel that increases as more compression is applied. These forks are lighter and thus better for climbing and agility due to a lighter front end. You will have to make more adjustments than you would with a coil sprung fork, but the benefits are definitely worth the extra time spent with set-up and maintenance.

Hydraulic Disc Brakes - Using a sealed, fluid filled system instead of a cable(mechanical disc brakes). Hydraulic brakes are the most efficient brakes on the market, with reduced friction and the highest level of braking consistency and modulation. A definite addition for fast riders that need to be able to stop quickly and safely whilst out on the trail.

Agile-Ride-Geometry - This is a design style where the rear end is shortened and the geometry of the frame is meticulously tested to ensure maximum mobility and drag reduction. Specifically designed for mountain bikes, the revised geometry allows for more comfort on the climbs and increased agility on the descents.

Thru- Axle - In place of more traditional quick release axles, Thick Thru-axles allow for a stiffer and more responsive ride by making the wheel's rigidity increase by inserting directly into the fork. This allows more more symmetric forces to be supplied to the forks and suspension. Overall this creates a smoother and controlled feel to the bike, with the added thickness reducing the risk of splitting your axle after a particularly big jump.

The all-new Reaction range for 2018
