Stems

- Lightweight, 3D forged, 2014 aluminum alloy - Proprietary Stealth recessed cable routing system enhances aerodynamic performance - Oversize box-section increases torsional stiffness with tuned vertical compliance

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored color is available on the Zipp Service Course stem. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering methods, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems. - Class-leading stiffness-to-weight ratio - More options for a better fit - New faceplate and geometry for greater stiffness and easier installation - Distinctive silver finish

- 3D forged 2014 aluminum alloy with oversized box cross-section - Oversize 46mm wide 6061 alloy faceplate - Steel hardware - ± 8° rise requires fewer spacers - 1-1/8" steerer adapter included

RR2.0 stems are designed with a low stack height and negative rise for road bikers looking to lower their handlebar position. They are made of high-grade aluminum to achieve the perfect balance of strength, stiffness and low weight. The body is 3D forged from an advanced 7075 alloy and the broad four-bolt faceplate design better distributes stress and lowers the clamping force required to secure the handlebar. - Designed for road use, but also suitable for mountain use - Forged and machined AL6061 body - 4-bolt face plate helps distribute clamping load - Corrosion-resistant Torx T25 steel bolts - Compatible with all 31.8 bars - 1 1/8" steerer - Includes stem top cap and bolt

Dimension 31.8 Stems are fully forged 6061-T6 aluminum stems that have a 4-bolt handlebar clamp. - 31.8mm can be used with 26.0 bars with additional shim (SM5317) - Dimension stems are not intended for use with carbon handlebars or carbon steer tubes - Weight: 130g-180g

The RR 2.0 stem offers a solution for integrated cables on Scott Addict/Speedster models, routing them under the stem and into the headset. KEY FEATURES - Integrated cable solution - Easy access to cables for service - Alloy AL6061 construction RANGE OF USE: ROAD MATERIAL: Alloy AL6061 ANGLE: -6° CLAMP DIAMETER: 31.8mm STEERER DIAMETER: 1 1/4" LENGTH: 70mm, 80m, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm WEIGHT: 230g 110mm)

Ritchey's 4-Axis Adjustable Stem features a precision 3D-Net shaped forged shaft that interconnects with a precision broached clamp to create the strongest, lightest, most secure adjustable stem available. - Stainless steel bar and steerer clamp bolts - Stack Height: 40 - Weight: 219g
