Ritchey WCS Skyline Bike Saddle (V2) - Black - One Size}, Black
  • £80.49
  • RRP £87.99
  • Saving you £9

Ritchey WCS Skyline Bike Saddle (V2)Engineered for the demands of modern road cycling and mountain bike (MTB) riding, this versatile saddle is well-equipped for wherever your next ride takes you. With a premium Ritchey synthetic upper cover, this model is designed for long days on the road and all-day epics in the mountains. Its shell uses two materials, so riders can benefit from the flexibility of its nylon properties and the strength and low weight of its carbon fibre. Coming kitted out with tough stainless steel rails, this version provides a secure hold to your seatpost as you tackle every terrain. Keeping the ergonomic curve that supports sit bones and the generous cut-out to relieve perineal pressure just like the original Skyline, this model is also equipped with an updated construction for more durability, better aesthetics and a lighter weight. Versatile Saddle with Superlight Polyurethane FoamBuilt with a unique manufacturing technology that adheres the saddle cover to the base without any visible seams, glue, stitching or staples, the updated WCS Skyline is now waterproof, will last longer and keeps the weight to a minimum. The saddle padding is made from a lightweight polyurethane material that is 30% more shock absorbent than traditional foam, which reduces rider fatigue.Vector Wing TechnologyLike the original, this WCS Skyline features a curved, two-axis shape that brings a rise towards the rear of the saddle and a bit of lift to the nose. This shape is ideal for riders who lack flexibility and want more support, yet still offers a good position for riders who demand a healthy dose of performance with their comfort. Another highlight of the Skyline is Ritchey's revolutionary patented Vector Wing technology, which helps eliminate hots spots by dissipating pressure more evenly for all-day comfort for wherever your pedal strokes take you - road, gravel, trails and beyond.Features: Cover Material: Premium Ritchey Synthetic upper Shell Material: Nylon and Carbon Fibre Rails Material: Stainless Steel Padding Material: Superlight Polyurethane Foam Use: Road, MTB Size: 277x147mm Rails Size: 7x7mm Vector Wing design Curved two-axis shape Seamless cover and shell integration Weight: 227gBuy Ritchey Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Ritchey Trail Mountain Bike SeatpostOne of the lightest and toughest aluminium models on the market, the Trail Mountain Bike (MTB) Seatpost is the perfect addition to your modern hardtail or full-suspension machine.
