Stems

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

The Elite X4 Mountain Stem is instantly recognizable because of Thomson's legendary style, and with strength to spare, this stem is more than just a pretty face. Made from a solid, one-piece block of 7000-series aluminum, the X4 combines exceptional strength with light weight for durable, solid steering control to tame the toughest trails. It has a four-bolt clamp design and reversible graphics, so your X4 looks great whichever way you run it.

From road to mountain, Syntace's Force 109 stem offers a variety of lengths in a 6° rise with thoughtfully engineered features. It's oversized stem tube diameter offers increased stiffness, and titanium bolts shed unecessary weight. A 200 degree clamp face helps increase handlebar strength and fatigue life. - Stack height: 38.5mm - Weight: 118g (110mm)

Syntace's Megafroce 2 stem is intended for all-mountain and downhill riding and comes in a range of sizes with a focus on torsional stiffness and weight savings. The 42mm wide bar clamp area stiffens up cockpits with bars wider than 700mm Titanium bolts help keep the weight low and strength high. - Stack height: 36mm - Weight: 132g (70mm)

- CNC machined 2014 aluminum body and 7075 aluminum clamps - 240 degree wrap-around, twin plate clamping system - External webbing to maximize structural strength - 118-158g including stainless steel bolts

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.

Profile's Aris OS stem is a no-nonsense stem made from 6061-aluminum that's been shot peened and anodized for strength and durability. The 4-bolt faceplate is stiff, ultra tough and makes handlebar changes a breeze. And, the opposing-bolt steerer clamp is safe and secure.

3D-forged and CNC-machined AL6061/T6 mountain bike stem. - 4-bolt cold-forged alloy faceplate - Chromoly hardware - 40mm fork clamp stack height

Inspired by the sleek and deadly lines of a Copperhead snake, the sweeping center channels of the Copperhead stem wrap around the entire stem to minimize material while delivering a strong steerer-mounted stem. Deity's focus on durability and dedication to the symmetry between strength and weight is showcased in the balance of style and function that is the Copperhead stem. - Designed for all applications from All MTN to Slopestyle and anything in between - CNC Machined from a solid block of 6061 T6 Aluminum - Exceptionally detailed chamfered edges and channels throughout - Material: Aluminum - Length: 35mm or 50mm - Stem Angle (deg): 0 deg - Weight: 135g. (35mm); 161g. (50mm)

Designed for use with Cannondale's Headshok (sold separately), the Headshok Stem is tough, light, and ready to ride. - Sleek styling with maximum strength and stiffness - Forged from a single block of lightweight 2024 aluminum with our patented OPI 3D forging process, these stems are exceptionally light and strong - 31.8mm clamp interface - Weight: 185 grams (100mm length)
