Ritchey: The front of the new Ritchey RL1 Switch stem features Ritchey’s legendarily logical four-bolt handlebar clamp design seen on many Ritchey stems – it’s stiff, practical, and secure. Beyond that, the heart of this innovative stem is designed to stealthily conceal cables into the headset and frame. Up to three cables – such as for the rear brake, shifter, electronic drivetrain or even dropper post - are effortlessly integrated with the Ritchey Switch System spacers and Switch headset (both sold separately) to cleanly route the hidden cables into the frame. Ritchey RL1 products are designed and built for the budget-minded cyclist looking for components to upgrade their current ride or to complete their next build - without compromising on the confidence and quality for which Ritchey products are known. About the Ritchey Switch SystemThe Ritchey Switch System is an innovative integrated system designed to easily conceal internally routed cables, wires, and hydraulic lines from the handlebar into bicycle frames with straight 1.5" head tubes together with tapered 1-1/8" – 1.5" forks. The Switch System consists of three elements:
Switch Headset
Switch Headset Spacers

Ritchey: You really can have it all—the sexy silver WCS C220 stem rivals the performance of the revolutionary C260 stem design, but it's quicker and easier to install and remove, thanks to a press-fit handlebar clamp interface and forward-facing hardware.First proven on the Ritchey trail stem, the C220 handlebar clamp design creates a more secure interface by wrapping a full 220° over the handlebar. Bolt forces are aligned with the clamp so that the stem body 'embraces' the handlebar, which is less prone to damaging lightweight bars. This clamp design allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness.The stem body is forged 2014 aluminum for further weight reduction. Premium quality stainless steel bolts are used throughout.

Ritchey: Recently added to Ritchey’s legendary WCS line-up of high-level components, the Switch stem now enjoys the legacy of the rainbow stripe WCS logo and the numerous World Champions that have won on Ritchey. The front of the Ritchey WCS Switch stem features the tried-and-true Ritchey C220 handlebar clamp design seen on many Ritchey stems, but we've increased its width for additional stiffness. We’ve also rotated the clamping area a few degrees downward to create a flatter and more aerodynamic top stem section.But wait, there’s more! The front of the WCS Switch stem also includes a reversible accessory mount. Designed to accommodate accessories such as cycling computers, cameras, and power meter head units, this mount is completely hidden within the front clamp of the stem until you decide to mount your favorite accessory.Aside from all of that, everything else on this innovative stem is new and designed to stealthily conceal cables into the headset and frame. Up to three cables – such as for the rear brake, shifter, electronic drivetrain or even dropper post - are effortlessly integrated with the Ritchey Switch System spacers and Switch headset (both sold separately) to cleanly route the hidden cables into the frame.

Ritchey: The new Ritchey WCS Toyon stem takes its lead from the original, award-winning Ritchey C220 stem and gives it a more modern shape and increased stiffness for improved handling and greater responsiveness. The 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 body 'embraces' the handlebar – a design which 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 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.
