Ridley Fenix SL40 - Unisex


See available road bikes


With its light, layered carbon fibre frame, the Fenix SL40 is a responsive, comfortable ride that blurs the line between race bike and endurance bike. On high-spirited KOM attempts or finishing sprints, the tapered head tube and massive pressfit BB create a direct transfer between you and the pavement. Detour onto back roads, and the Fenix's endurance roots come to the fore. When descending, the flattened chainstays and tire clearance (up to 28mm) offer a compliant ride without sacrificing race-ready stiffness. Mavic Ksyrium wheels are proven performers – durable, adventurous, responsive when you need extra punch, and they won't weigh you down on climbs. Equipped with one of the best gruppos around, it gets a workhorse 11-speed Shimano Ultegra R8000 drivetrain that balances performance and reliability. When coming in hot to technical hairpins, the Ultegra brakes produce confidence-inspiring, catch-free power and nuanced modulation.
