      • i C10 Carbon Frame

        Boardman's C10 Carbon uses ultra high modulus fibres in key areas of the frame and fork, boosting stiffness whilst reducing overall frame weight

        Boardman's C10 Carbon uses a mixture of Toray T1000 and T800 or equivalent fibres. These high modulus fibres have outstanding stiffness to weight ratios, meaning that we can use less material to produce the same level of stiffness compared to lower grade fibres. This in turn means we can shape tubes more dramatically to tune the performance of the frame to suit the type of riding it is designed for. In the SLR Endurance Disc range, the use of C10 Carbon facilitates a super stiff head tube, comfort enhancing seat stays, and efficient chain stays for outstanding power transfer.

      • i Tapered full carbon fork

        A tapered, full carbon fork with a 1 1/2 inch lower headset bearing increases stiffness and steering precision

        The interface between the fork and the headtube is responsible for transmitting all of your steering inputs into your wheels, so is a key component in giving you confidence in your bike's handling. We use an oversized 1-1/2" lower headset bearing to allow a smoother flow of fibres from the fork crown into the steerer tube, increasing both stiffness and durability of the fork. This translates into better steering feel and control, whether carving down an alpine descent or negotiating your way to the front of the group on a big sportive. A tapered, full carbon fork with a 1 1/2 inch lower headset bearing increases stiffness and steering precision.

      • i FEA developed frame

        The frame has been developed using Finite Element Analysis (FEA) to put material where it is needed and remove it where it isn't, reducing frame weight to 950g, whilst ensuring stiffness and strength are maximised

        It's not difficult to build a super stiff frame out of carbon fibre - just add plenty of material into each of the tubes to make sure there's no unwanted flex. Using this approach however, ends up with a frame that you could also use as an anchor for a small boat.

        Using Finite Element Analysis, we modeled the stress that goes through the frame as you pedal and hit imperfections in the road. This let us increase the amount of material in areas of high stress, and remove it from low stress areas. By doing this we have built a frame that is not only incredibly stiff, but also incredibly light at 850g for a medium frame. 

      • i Endurance focussed geometry

        The geometry of the SLR Endurance Disc Disc offers stable handling and a comfortable but efficient position to cope with all endurance events and race situations

        We took a different approach to most when developing the geometry for the SLR Endurance Disc frame. We wanted the bike to be comfortable to ride over long distances, but still have the nimble handling to offer a fun and engaging ride. We took the proven, aggressive geometry of our race platform and added height into the headtube to give a slightly more upright position without compromising on speed. This isn't a sedate, sit up and beg endurance bike; it is a perfect combination of comfort and agility, offering fast but predictable handling to keep the smile on your face all day long.

      • i Comfort optimised seat stays

        Narrow profile seat says offer high levels of comfort, absorbing shocks and reducing road vibration passed through to the saddle

        Comfort is a key part of the SLR Endurance Disc's DNA - and part of this is delivered through slim profile seat stays. There is minimal lateral force transmitted through the seat stays while pedalling which means we were able to reduce the amount of material used, and tune the carbon fibre lay up for optimum comfort and shock absorption. The small amount of flex built into the seat stays reduces the amount of road buzz transmitted to the saddle, and helps to take the edge off harder impacts from poorly maintained road surfaces.

      • i PF30 Bottom Bracket

        PF30 gives a wider bottom bracket shell allowing us to profile the chain stays for outstanding power transfer

        The PF30 bottom bracket comprises of bearings in a plastic housing pressed directly into the frame. This means that the bottom bracket shell can be wider compared to a threaded bottom bracket as the bearings sit inside the frame, not outside. We've taken full advantage of this additional width to provide a solid and stiff junction between the BB and the chain stays to ensure your power is going into the road as efficiently as possible.

      • i Thru Axle & Disc Brakes

        Hydraulic disc brakes give consistent, powerful and controlled braking in all conditions, combined with 15mm front and 12mm rear thru axles for optimal strength and steering precision under hard braking or cornering

        Rim brakes have worked adequately for years, so why do you need disc brakes? Modulation is the answer. Hydraulic disc brakes offer huge amounts of braking force, which you can control with just a single finger, meaning you can adjust how much braking power you are using in a fraction of a second. This lets you fully exploit the grip available from your tyres to bring you to a stop in as quick a time as possible.

        When this is combined with thru axles, which securely lock your wheels into the dropouts, the result is outstanding braking and steering, perfect for descending alpine passes or dodging the potholes on the club run.

      • i Tyre Clearances

        Clearances for up to 28mm tyres for further enhanced comfort and grip

        The trend in recent years has been to fit wider tyres on road bikes. They allow you to run lower pressures for greater comfort and grip, or offer lower rolling resistance at the same pressure as a narrower tyre. The SLR Endurance Disc comes as standard with 25mm tyres, which are a great compromise between comfort, grip and speed, but has clearance to size up to 28mm for an even plusher ride if needed.
