You really can have it all; Ritchey's WCS C-220 stem features revolutionary stiffness and classically inspired good looks, but it’s quick and easy to install and remove thanks to a press-fit handlebar clamp interface and forward-facing hardware. The C-220 handlebar clamp design creates a more secure interface by wrapping a full 220 degrees 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 chromoly steel bolts are used throughout. - Material: 3d forged 2014 alloy body - 4 x 4mm coated CrMo steel forward-facing faceplate bolts - 2 x 4mm coated CrMo steel offset steer tube clamp bolts - 5Nm torque max on all hardware - Compatible with all 31.8 bars - Press-fit clamp design installs and removes like a standard stem - Angle: 84/6 degree - Steerer Height: 42mm - Steerer diameter: 1-1/8" - Faceplate Width: 42mm - Silver Finish - 121g (110mm)

Precision 3D-Net shaped forged shaft interconnects with a precision broached clamp to create a strong, light, and secure stem offering +/-55 degrees range of adjustment. - Adjustable from +40 to -32 degrees - Stainless bar and stem clamp bolts

When stiffness and weight are the top on your list, you want Ritchey's SuperLogic C-260 Carbon Stem. This revolutionary design starts with a bar clamp that wraps a full 260-degrees around the handlebar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. Ritchey's first full-carbon stem, the C-260 features high-modulus carbon for stellar strength-to-weight ratio that translates into a solid but forgiving ride. And, the steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube, so you can run carbon bars and a carbon steerer with no problem.

- C-220 degree extra-wide bar clamp improves stiffness and fits most riser bars - 3D forged 6061 alloy - 42mm steerer height with 41mm faceplate width - 142g (90mm)

You really can have it all-the 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. The WCS C22 84D Stem offers 6-degrees of positive or negative rise. First proven on the Ritchey Trail Stem, the C220 handlebar clamp design creates a more secure interface by wrapping a full 220 degrees 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.

Recently added to Ritchey’s legendary WCS line-up of high-level components, 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. The Ritchey WCS Switch stem includes a matching compression cap.

Built for all-mountain riding, the new Aeffect Rally 35 stem is a no nonsense workhorse. With increased strength and shorter length options available for modern bike geometry, Aeffect R performs well above its price point…and all of this at a competitive weight.

RaceFace designed their Atlas 35 stem to reduce overall system weight while retaining the proven stiffness and performance the Atlas line is known for. The stem itself is measurably stiffer than the 31.8mm offering and, although the system is a seemingly burlier build, the weight savings gained by the reduction in bar material actually makes the 35 system lighter overall. An impressively light, strong addition to your aggressive trail or DH/FR build. - Four-bolt bar clamp holds bar securely in position - Interlocking U-Shaped Handlebar Clamp Geometry - Faceplate eliminates stress risers which cause your bar to bend or break - Opposing bolts on steer tube clamp provides extreme clamping power while reducing stress on the steer tube - Stack Height: 40mm
