FRS Direct Mount Stem

What Our Gearhead® Experts Are Saying:

"The PRO FRS Direct Mount Stem is one of the cleanest direct mount options I have specced on performance road builds at this price point. The AL-7075 CNC construction is immediately apparent in the fit and finish, and the Headlock front clamp system is a well-engineered detail that makes handlebar installation and adjustment fast and precise without any of the flex or movement you get from lesser clamp designs. At 172 grams and 45mm length it is purpose-built for an aggressive race geometry cockpit where stiffness and weight are both non-negotiable."

Direct mount stem technology exists to eliminate the compliance and weight inherent in traditional steerer-clamping stem designs, and the PRO FRS Direct Mount Stem executes that brief with the precision machining and material specification that a performance road build demands. Manufactured from AL-7075 alloy through a full CNC process, every surface and interface on this stem reflects a level of dimensional accuracy that contributes directly to cockpit stiffness and handlebar position repeatability across the life of the component.

The direct mount interface removes the steerer tube clamp from the equation entirely, integrating the stem with the fork's direct mount interface for a front end connection that is measurably stiffer and more responsive than a conventional stem and headset combination. That stiffness translates into more immediate steering response, better power transfer on out-of-saddle efforts, and a more connected feel between rider input and front wheel behavior on technical road and gravel surfaces. The Headlock front clamp system secures a 31.8mm handlebar through a front-loading design that simplifies bar installation and adjustment while maintaining a clamp interface that resists movement under hard torque loads and repeated impact.

At 45mm in length the FRS Direct Mount Stem is positioned for riders on aggressive race geometry frames where a short stem length is part of the overall cockpit and handling equation, working in conjunction with wider handlebars to deliver a front end that is both stable and highly responsive. The 172 gram weight keeps the cockpit contribution to overall bike weight minimal, a consideration that matters on builds where every gram across the contact points and cockpit components is evaluated against its performance return.
