Deda 35 (Trentacinque) Stem
The Deda Elementi 'M35' handlebar and its stem TRENTACINQUE are the greatest innovation in the field of components for high performance road racing bicycles. No handlebar in the world has such a diameter.
The diameter is the main factor of magnitude in the moment of inertia of the section of the handlebar. The moment of inertia is what defines the rigidity of your handlebars - what all riders are looking for, as insufficient stiffness causes dissipation of your precious energy. The M35 is a single piece carbon fiber monocoque with different wall thicknesses to put more strength precisely where it is needed.
The fiber used has features specifically designed for competition vehicles where a very high tensile strength is married to an extraordinary capacity for absorbing vibrations. The larger diameter allows for better hand and lower specific pressure, resulting in reduced hand fatigue.
The stem TRENTACINQUE is a 3D 2014 alloy forging with different wall thicknesses. Use of the M35 and TRENTACINQUE gives an entirely different and completely new feel while riding.

WCS 4-Axis 44 (31.8) Stem
WCS (WORLD CHAMPIONSHIP SERIES) - These words evoke the core philosophy behind Ritcheys highest performance components. The rainbow stripe WCS logo represents the numerous world champions that have won on Ritchey. The WCS line is the gold standard for lightweight, bombproof race parts and cutting edge innovation.
Tom Ritcheys original 4-Axis stem changed stem design forever. From the stress-managing forged faceplate, bolt spacing and angled steer tube slot to the now-ubiquitous 3D net forging process, the 4-Axis is still the standard in lightweight, stiff and strong stems.
Features:
- 4 Axis Technology
- 31.8 clamp diameter
- 3D-Net forged from 2014 alloy for a superb strength-to-weight ratio
- Specially designed, forged and contoured 4-bolt faceplate for use with today's lightweight, oversized carbon and alloy bars
- Bias cut clamp slot for a more secure, pinch free hold of alloy and carbon steerer tubes
- Stainless steel taper head bolts

Ritchey WCS C260 (31.8) Stem
Ritchey WCS C260 (31.8) Stem. Weight: Weight 103g. 3D forged and internally machined 7050 alloy body.
Ritchey WCS C260 (31.8) Stem
At 103 grams this is lightest, most advanced alloy stem in the Ritchey line, and possibly the world.
This revolutionary patented design starts with a bar clamp that wraps a full 260 degrees around the handlebar to distribute clamping stress more evenly through the handlebar, faceplate, hardware and stem body. The steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube.
The body is 3D forged from an advanced 7050 aluminium and internally machined for further weight reduction. Premium quality CrMo steel bolts are used throughout, but in a smaller M4 size that shaves a few more grams with no sacrifice in strength or rigidity.
The resulting CEN-approved stem is 20 grams lighter and even stiffer than our already stiff and lightweight 4Axis.
Details:
- 3D forged and internally machined 7050 alloy body
- 4 x M4 faceplate bolts and patented 260 degree bar clamp design reduces weight, increases stiffness and distributes stress more evenly
- 3 x M4 steer tube bolts and curved clamp slot reduces weight and steer tube stress
- 5Nm torque max on all hardware, same as 4Axis stems using M5 bolts
- 30% stiffer than Ritchey's legendary WCS 4Axis and 20 grams lighter
- Fits most road and mountain bars
- Weight: 103g

Zipp Service Course (31.8) Stem 6 Degree
Zipp Service Course (31.8) Stem 6 Degree, High-strength 3D-forged construction and 7075 aluminum.
Zipp Service Course (31.8) Stem 6 Degree
Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. It's a difficult job, but the new Service Course stem is still able to combine strength, stiffness, and reliability at a weight of 130 grams (100mm).
High-strength 3D-forged construction and 7075 aluminum deliver an exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames. During production, we take extra steps to ensure precise length and alignment across a range of fourteen sizes to meet any rider's fitting needs.
