Turbine SL matches the versality of modern short travel bikes. It brings adjustability, tunability and aesthetics to more riders. It’s damn light, looks great and it’s ready to go big on little bikes. Designed for up to 140mm travel bikes, Turbine SL gives riders the choice of running a negative (-6mm) or positive (+6mm) offset. Whether you prioritize XC efficiency or comfort and descending confidence, this is a stem that matches your bike’s versatility. Turbine SL’s default orientation is negative offset, giving riders better climbing control and pedaling efficiency. In this orientation the stem’s top surface is completely flat, offering aesthetic appeal and an ideal surface for headset spacer-style or "over-the-stem" cycling computer mounts. Flip Turbine SL for a +6mm offset stem and a 12mm boost in cockpit height (compared with negative orientation), without adjusting the position of headset spacers. A higher cockpit encourages a more capable and confidence-inspiring descending position. It also lets riders sit more upright and comfortably when pedaling. 6000-series machined aluminum Use classification 4 (Trail) Top-lock faceplate. For a clean cockpit Refined bolt finish.

When the gear couldn't keep up with the riding, they made their own, parts that are strong, lightweight, and durable; that perform better.
