The SL R frameset is manufactured from a carefully selected blend of Toray’s T1000 and T800 carbon fibre, using more of the T1000 carbon layup than any other frame in the Ribble range. This unique mixture of carbon is layered to an
exacting specification using an advanced monocoque mould technology, incorporating an EPS inner core system that 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 and in turn eliminates any weak spots in the construction.
Aerodynamics have been a major consideration in the development of the new Endurance SL R with the new frameset generating up to 28.5% less drag compared to the previous generation.
Aerodynamic drag saving features include,
- Truncated aerofoil down tube
- Aero fork blade profile
- Truncated aerofoil seat tube and seat post
- Internal cable routing
- 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 downtube, oversize BB area, and box section chainstays ensuring that your power wattage is efficiently transferred to forward motion. The tapered fork
steerer, oversize headtube area and fork profile ensure that front end stiffness is taken care for out of the saddle efforts.
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 is smooth and comfortable
over rough road surfaces and long distances.
The SL R frameset has discreet mudguard mounts and tyre clearances for up to 30c tyres or 25mm with mudguards fitted, ensuring that the Endurance SL R can be ridden throughout the seasons, whatever the weather conditions.
