With its impeccable performance, versatility and a multitude of wheel, component and finishing kit options the Endurance SL R Series can be fine-tuned for all riders of all levels of experience and ability.

The serious racer whether Elite or local hero will appreciate the frames stiffness and power transfer. The built in aerodynamic tech, builds tipping the scales below the UCI weight limit and disc and caliper brake options mean the Endurance SL R Series platform offers a performance advantage in all race situations.

The experienced Endurance rider will benefit from the road racing bikes attributes designed into the frame and will also see gain from the comfort enhancing and fatigue reducing features ensuring that they can go further, higher and quicker whether all day Epic or Weekend Gran Fondo..

Fitness and Leisure riders can experience the feeling you only get from a super high end race bike but with the geometry and fit required to achieve a comfortable and efficient riding position. The platforms comfort, stability, handling and braking performance will inspire confidence making the Endurance SL R Series the perfect partner as you develop you riding ability. Ride further and faster with less fatigue, make light work of hills, as you progress to experience longer rides over more challenging terrain.

The SL R Series frameset is manufactured from a carefully selected blend of Toray’s carbon using more of the T1000 grade than the standard SL and layered to an exacting specification to reduce weight without compromising stiffness and strength. The frame is crafted using advanced monocoque mould technology incorporating an EPS inner core system which ensures complete consistency of the structural integrity of the fibres and resin throughout the frame. This system also eliminates excess material on the inside of the frame.

Aerodynamics have been a major consideration in the development of the new Endurance SL R Series with the new frameset generating up to 28.5% less drag compared to the previous generation. The aerodynamics are further enhanced by the new integrated carbon cockpit system which generates over 40% less drag than a conventional handlebar set up.

Aerodynamic drag saving features include,

1, Truncated aerofoil down tube

2, Aero fork blade profile

3, Truncated aerofoil seat tube and seat post

4, Internal cable routing

5, Optional aero one piece cockpit enabling all cables to be routed internally and away from the airflow generating over 40% less drag compared to a conventional bar and stem set up (disc brake version has all cables completely hidden and caliper brake just the front brake cable).

Power transfer and torsional stiffness have been taken into account through the tapered oversize downtube, oversize BB area and box section chainstays ensuring that your power wattage is efficiently transferred into forward motion. The tapered fork steerer, oversize headtube area and fork profile ensure that front end stiffness is taken care of when sprinting or climbing out of the saddle.

Comfort through road surface impact and vibration absorption is very important in an Endurance bike and the specific shapes and profiles of the seat stays, seat post and carbon cockpit ensure that the Endurance SL R Series is smooth and comfortable over rough road surfaces and long distances.

The SL R Series frameset has discreet mudguard mounts and tyre clearances for up to 30c tyres ensuring that the Endurance SL R Series can be ridden in all seasons and weather conditions.

1. Optional carbon integrated cockpit with full internal cable routing

2. Tyre size compatibility – Up to 30c

3. Direct mount brakes for better braking performance

4. Internal cable routing and Di2 compatibility

5. Mudguard fitments and clearance – For all weather riding

6. Seat stay profiles designed for vertical compliance and vibration absorption enhancing comfort

7. Oversize tapered down tube and chainstays for torsional stiffness and power transfer

As well as using more higher grade carbon in the construction the SL R Series utilises carbon rather than alloy for the headtube and BB inserts reducing frame weight. A special paint and decal finish is also applied further minimising weight resulting in a total weight saving of approx. 300g vs the standard SL frameset making it ideal for the discerning rider and racer looking for the ultimate in Endurance and versatile race bike performance.
