The Race Face Turbine SL stem matches the versatility 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.
One Stem. Two Solutions
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.
Short travel is cool again
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. Available in lengths up to 60mm.
Level-up your little bike
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.
