Often times, carbon gets all of the attention, but as our Senior Advanced R&D Engineer, Chuck Teixeira, says, "If you haven't ridden an aluminium bike lately, you haven't ridden an aluminium bike." And with its D'Aluisio Smartweld frame, the Chisel Expert with one-by gearing is no exception.
Traditional welding methods create frame joints by connecting tubes to cylinders, leaving the performance and security of the connection up to the skill of the welder. D'Aluisio (DSW), however, allows us to move the joint away from the area of the highest stress, making for a lighter frameset that's stiff, compliant, and incredibly strong—the optimal characteristics of a hardtail XC rig. So what does this mean for you? You'll be powering up climbs, shredding singletrack, and everything in between on a bike that has you questioning why alloy as gotten such a bad rap.
And to further improve this feel, the Chisel also features our XC 29 geometry which took our previous XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked out front end, the result of which is a tremendous increase in downhill stability, plus a wider range of fit. And just as importantly, this doesn't require any sacrifice of climbing proficiency.
The build on this Chisel features a mix of SRAM GX and NX one-by components for efficient shifts and added protection against dropping the chain. You'll also find powerful SRAM Level TL hydraulic disc brakes, a dependable RockShox Reba RL fork with up to 100mm of travel (size-specific), and 25-millimeter-wide alloy wheels that are optimized for weight and traction.

Given its lightweight and ultra-stiff characteristics, M5 aluminium was the natural choice for the frame's construction. And when complemented with our speed-focused XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance.

A custom RockShox Reba RL 29 fork offers up 90/100mm of smooth travel (size-specific), while an easily accessible compression and rebound adjusts permit you to customize the feel according to the terrain at hand.

SRAM GX handles one-by shifting duties, practically eliminating dropped chains and reducing overall bike weight.
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.
