Support the Trails and Your Local Trail Builder!

As part of our Trail Builder series this stem was designed to hold like a trail builder’s grip on their tools. This fully CNC-machined stem has an incredibly precise bar interface that’s light enough for your race bike and strong enough for gravity rides.

Available in 35mm, 50mm and 65mm lengths, the Builder stem uses a carbon and alloy friendly bar/stem interface with an increased clamping surface. By increasing the clamping surface area and utilizing our controlled clamping system we have created a stronger and more precise stem.
