Titanium hardware and weight-reducing CNC machining takes the ShockStop PRO Suspension Stem to the next level of performance. Enjoy the same shock-reducing benefits of the standard ShockStop Stem with 15% less weight and a premium finish. Whether you're on a local group ride, or exploring gravel back roads, the ShockStop Stem will make your ride smoother, faster, and more comfortable. The new ShockStop PRO Stem blends seamlessly with the aesthetic of modern bikes, while reducing fatigue and strain. Along with the ShockStop Suspension Seatpost, this system works together to suspend the rider and smooth out rough terrain on the bike you already own, making your ride smoother, faster, and more comfortable.
