Ribble says that aerodynamics were a factor when developing this frameset and that it has 28.5 per cent less drag than its previous iteration. Maximum tyre clearance is 28mm, or 25mm if utilising the full mudguard mounts for year-round protection. Ribble claims a medium frame weighs 1,150g, plus a further 400g for the carbon fork. The monocoque Endurance SL frameset uses Toray T800 and T1000 carbon and is built with an internal EPS core that maximises carbon and resin compaction, and ensures consistent structural integrity. Every tube facing the airflow has an aerofoil profile.
