Ridley Fenix SL50 Road Bicycle - Unisex


See available road bikes


With its light, layered carbon fibre frame, the Fenix SL50 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 road. Detour onto backroads, and the Fenix's endurance roots come to the fore. When descending washboard gravel, the flattened chainstays and tire clearance (up to 28mm) offer a compliant ride without sacrificing race-ready stiffness. Mavic Aksiums are all around performers – tough, fast-rolling and aerodynamic. A frame this good deserves a certain calibre of components, so Ridley opted for SL50 with Shimano's excellent 11-speed 105 groupset and a host of proven 4ZA aluminum components to tie this whip together.

  • Flattened chainstays provide shock absorption for a comfortable, buzz-free ride
  • FSA Pressfit BB aids power transfer without adding weight
  • Revamped carbon fibre fork with carbon steer tube integrates into frame for aerodynamic gains
  • Internal routing aids aerodynamics while keeping cables silky smooth
  • Carbon fibre drop outs help cut overall weight, while the stainless steel inserts add protection
  • Mavic Aksium Elite wheelset with Mavic Yksion Elite Guard 25mm tires
  • Shimano 11-speed 105 groupset
