Ritchey Toyon Classic Stem 84 Degree 31.8mm - High Polish - 1.1/8", High Polish
  • £58.49

Ritchey Toyon Classic Stem 84 Degree 31.8mmEngineered for all-day epics on the trails, this mountain bike (MTB) stem features a tough 2014 alloy construction. Ritchey has also equipped this model with stainless steel bolts for a strong and secure hold between your handlebars and your fork's steerer tube. Another highlight is its high polish finish, which gives it a sleek, eye-catching appearance on your ride.Alloy MTB Stem with High Polish FinishThe Ritchey Classic Toyon stem takes its lead from the original, award-winning Ritchey C220 and gives it a more modern shape, a timeless aesthetic and increased stiffness for improved handling and greater responsiveness. Available exclusively in a 60mm length, the Classic Toyon is the perfect match for the Classic Kyote with its extended backward sweep. The Classic Toyon retains the clamping surface area of the C220, which creates a more secure interface by wrapping a full 220° over the handlebar. Its bolt forces are aligned with the clamp so that the stem body 'embraces' the handlebar - a design that is less prone to damaging lightweight bars and allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness. Built from life and all that inspires it, the Classic Toyon builds upon the proven and celebrated C220 design with a fresh, squared aesthetic that adds to the overall harmony of modern frame designs - matching its good looks with enhanced confidence and a more lively feel for wherever your rides take you.Ritchey MTB stems continue to enjoy the hard-earned privilege of gracing the bikes of the world's best mountain bike racers. World Cup winners, Olympic gold medallists, national champions, world champions, they have all run Ritchey mountain bike stems. Each Ritchey stem is the result of a rich heritage of mountain bike innovation, research, testing and design. This is clearly evident each time you suit up and head out for a great day of MTB riding.Features: Stem Material: 2014 Alloy Bolts Material: Stainless Steel Use: Mountain Bike (MTB) Length: 60mm Bar Clamp Diameter: 31.8mm Bar Clamp Width: 44mm Steerer Diameter: 1 1/8" Steerer Height: 42mm Angle: 84 degrees / 6 degrees Weight: 115gTechnologies: Perfect match for the Classic Kyote handlebar (available separately). 6 degrees of positive or negative rise. 1-1/8” steerer diameter.Manufacturer's Part Number: 31075457001 Silver High Polish 60mmBuy Ritchey Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Engineered from high-quality alloy that is strong and lightweight, this handlebar is also compatible with the Shimano EW-RS910 junction box and Ritchey C260 stem.Optimised for Gravel and Adventure CyclingTom Ritchey has been riding off-road and riding far - and designing products for such adventures - decades before anyone thought to call it “gravel riding” or “bikepacking.” His real-life experiences directly inform every product made by Ritchey - such as the beloved VentureMax handlebar. With its short reach, shallow drop and purposeful flare, the original VentureMax offer comfort and confidence to legions of riders looking to settle in and have some fun on those dirty drop bar adventures. Shimano Di2 Junction Box CompatibleLike its predecessor, the new generation WCS VentureMax is influenced by those life experiences, but some additional new features - continuing to inspire riders to chase gravel and other mixed-surface adventures. Aero-shaped 38x22.5mm ergonomic tops offer a more comfortable hand position while drilling for a Shimano EW-RS910 junction box expands the adaptability of the WCS VentureMax. Enhanced Design for Comfort and ConfidenceMultiple hand positions are key for comfort and confidence on any ride, and the WCS VentureMax offers plenty of options there - especially with its wide 24-degree flare at the drops. But it's the return of the Bio-bend in the drop that adds yet another design element that is practical and comfortable for whatever surface you choose to ride upon and for however long your adventure endures.
