When you leave the rest behind on the GTC SL, it'll be clear why. There's simply no serious competition for this standard-setting racer, whether in 27.5in or 29er wheel options. In either case, the GTC carbon frame with high performance, lightweight components - a complete XT group and new Fox 32 Float Performance SC suspension fork - is the ideal bike for cross-country, marathon racing or just epic day rides.
Next to the Reaction GTC frame, even some pro team race bikes may come up a bit short. We've built this chassis to be both light and stiff, by using sophisticated construction with our GTC Twin Mould technique and applying modern technologies like the tapered head tube, PressFit bottom bracket and an X12 quick release axle. The slim 27.2mm seatpost adds a little extra comfort and, with Agile Ride Geometry (ARG), there's no compromise in the handling department.
Consistently perfect performance - even in bad weather conditions - is what the 2x11 Shimano XT transmission and powerful, accurate XT hydraulic disc brakes are all about. The new-for-2017 Fox 32 Float Performance SC suspension fork with 100mm travel features a handlebar lockout and provides smooth, controlled bump absorption without wasting any of the rider's energy. Even better, new cast lower legs mean a substantial 200g weight saving without sacrificing strength or steering accuracy. Exceptionally light Fulcrum Red Power wheels with 23mm rims endow the GTC SL 2X with blistering acceleration. Contact points blend performance and comfort - they include the Selle Italia SC1 saddle and a CUBE cockpit designed for optimum ergonomics.
Mountain biking has been revolutionised in the last few years with the introduction of larger wheel sizes and more sophisticated suspensions. Whether you are buying your first mountain bike, or you want to upgrade your ride, this is a quick guide to steer you through the occasionally confusing world of mountain biking. For a far more detailed guide, go to our BLOG on finding the mountain bike for you.
Where to start
Prices for a mountain bike that will last and give you a proper riding experience start around £400, which includes bike set-up and your first service. On bikes over £600, we include a free suspension set up, which is a £45 value. You can spend less on a bike, but you'll either get sub-standard components or be left on your own to build up the bike, fit it correctly, tune the suspension and service it once it beds-in.
What are you paying for?
£400 - £4,000 is quite a range, so how do you decide what's right for you? For example, is it more important to spend extra to get a carbon fibre frame or would you be better off with a less expensive frame and better gear shifters, brakes and wheels? If it's an upgrade from your current bike you are looking for, how do you choose the best frame, groupset and wheels for you?
1. Your Mountain biking objectives
The best place to start is understanding what you want to achieve with your bike. Are you riding local bridleways and towpaths, or will you be a regular on the red runs at Swinley Forest and the trail centres in Wales? Do you want to do big jumps, or be fast cross-country? The answers to these questions will guide you toward the right kind of bike. To keep it simple, we will refer to "Cross country", "Trail" and "Downhill". There is a more detailed breakdown in the BLOG
2. Frame materials
The most common material is aluminium, as it's light and strong, and it is less likely to be damaged in a crash than carbon fibre. Carbon fibre frames can offer improve weight and stiffness, but all carbon is NOT equal. Cheap carbon is like riding a plastic bike, and it is unlikely to survive many crashes.
3. Suspension & frame angles
"Hardtail" bikes have suspension forks and a rigid rear triangle, but "Full Sus" bikes have a rear shock absorber as well. Quality Full Sus bikes start at £1,000, as the parts and manufacturing costs are higher. The suspension "travel" is matched to the type of riding you will do. Cross country bikes generally have 100 - 120mm or travel, Trail bikes have 140 - 160mm, and Downhill bikes go up from there. Downhill bikes also have a fundamentally different frame design, and very heavy duty shocks, so it's a specialist area.
4. Wheel sizes
All quality mountain bikes now come with either 27.5" or 29" wheels. The "traditional" 26" wheel is slower over rough surfaces and has less grip due to the smaller contact patch with the ground. In general, 29" wheels are a good choice for medium and larger hardtail bikes, and 27.5" wheels are the best for smaller frames and full sus bikes.
Summary
We are here to help you match you with the best bike for your riding objectives and budget. We'll make sure you get the right size and set it up correctly for you in any case, but we can also discuss the trade-offs and pro & cons of your different choices. We are all cyclists and enthusiasts, so we are keen and able to help.
