Tiny, rider-based companies have always been a driving force in mountain bike design and innovation. These are the guys who use the products—and they use the hell out of them. The Twenty6 Products F1 Direct Mount Stem is the product of a small group of Montana-based riders, a garage, a 3D computer modeling program, and a CNC machine. Directly based on rider experience and input, the F1 has all the performance features that you would expect from a high-end race component plus adjustability and rare no-compromise quality.
