Cube’s Reaction TM Pro is great looking and even better value: It’s for riders who want a tough, well specced, aggressively agile play bike but don’t want rear suspension or long-reach stability. It’s a bit short, but otherwise Cube’s latest hardcore hardtail is one of the best new hardtail mountain bikes for heavy or heavy duty riders who want to ride more and wrench less. There are some decent full suspension bikes around for £1,500 now, but whatever the price point, a hardtail will always be lighter, with better equipment and less maintenance / set up stress. Cube’s Reaction TM Pro shows you don’t have to back off the attack much just because you’ve got no rear shock and it’s a great price too. There are some geometry aspects and kit that won’t suit everyone though. Frame and geometry The Cube Reaction Pro stands out straight away with a raw alloy finish and subtle silver reflective graphics. These make it look like an ultra cool boutique machine, not a mass market bargain. It also takes a lot of paint stress out of hard riding too as even if you manage to wound the thick clear lacquer you won’t see a scratch or scar. The belly and chainstay are protected with chunky rubber armour. The brake line gets secure bolt-on clips under the seatstay rather than just zip ties or those pointless U clips that come off immediately. The left offset brake routing through the top tube is a little bit awkward when switched to UK standard. Fixtures are bang up to date too with a UDH rear dropout, a bolted accessory mount under the flattened top tube and a bottle mount on the squared down tube. The bottom bracket has a three point mount for a full chain guide and you get an MRP 1x top chain retainer as standard. Bridgeless seat stays and a sculpted chainstay yoke give clearance for 29×2.6in tyres, despite the bike’s very short 427mm back end on the M, L and XL sizes. That back end shrinks to a crazy 408mm on the XS and S sizes, which get 27.5in wheels as standard. The seat tube is also short at 420mm leaving plenty of room for the 170mm stroke dropper, and the head tube is only 100mm tall too. Add a 462mm reach and you’ve got a really progressive medium sized bike. The trouble is, these are the numbers for the large, which really needs at least another 10-20mm of reach and a head tube height to match most competitors. And while the XL does get a 482mm reach, the seat tube grows disproportionately to 470mm, ruling out a long stroke dropper for large sized riders. However heavier riders – or anyone concerned about frame strength – will be stoked to hear that Cube’s 140kg rider weight limit is 20kg higher than most brands’. The angles are good too with a 65 degree head angle and an effective 75.5 degree seat angle. Components Cube matches …Continue reading »

| Frame | Aluminium Superlite, Gravity Casting Technology, Agile Ride Geometry, Boost148, Fully Integrated Battery, Advanced Internal Cable Routing, 1.5 Headtube, Kickstand/Fender/Carrier Mounting Points, Fully Integrated Battery, The Fully Integrated Battery system tucks the power of Bosch's battery out of sight, safely inside the confines of your bike's downtube. Hidden beneath a splash and dust-proof cover and secured with a lock to prevent theft, it allows us to design beautiful e-bike frames that are as brilliantly functional as they are good to look at. Advanced Internal Cable Routing, Gear and brake cables need a way to get from handlebar controls to frame – but what if there was no need for holes near the head tube? We came up with a design that takes cables into the frame via the headset, maintaining full internal cable routing but making it even neater and less obtrusive. Modular Battery System, In many ways the battery is the heart of an e-bike. That's why, with our Modular Battery System, we've made a setup that's easy to use. You can charge the battery on or off the bike, and we've made room for even high capacity batteries. You'll wonder how you ever managed without it. Size Split, The right bike should fit you perfectly. That's why we created Size Split. For shorter riders, the smaller 27.5in wheel standard allows us to build frames that fit well while remaining agile and sure-footed. And, for taller riders, we built a range of sizes around the fast-rolling 29er wheel standard. Whichever one you choose, you can be sure of a fit that makes your bike feel as though it was built just for you. Agile Ride Geometry, 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... Aluminium Superlite, CUBE's Aluminium Superlite starts with heat-treated 6061 aluminium, which has the qualities – high fatigue resistance, good stiffness, low weight and excellent strength – that are important for a bicycle frame. Then we make it into double butted tubes, to reduce weight without sacrificing any of its strength. The result? Exceptionally light, strong and tough frames. X-Connect, X-Connect is the simple way to attach a compatible ACID light to your CUBE bike. With a connector built into the headset and the wiring hidden in the frame, all that's left to do is attach the light, plug it in... and off you go. See and be seen, the easy way.
