AL-2014 Aluminum Construction
The PRO PLT stem is manufactured from AL-2014 aluminum alloy, a material selected for its mechanical properties and suitability for bicycle cockpit components.
Its construction provides the structural support required between the fork steerer and handlebar while maintaining a relatively lightweight design.
For cyclists seeking a dependable aluminum stem without moving to a carbon cockpit, the PLT offers a practical combination of functionality and straightforward construction.
Reversible ±6° Angle for Cockpit Adjustment
The stem features a reversible ±6° angle, allowing it to be installed in either an upward or downward orientation.
This provides an additional option when adjusting handlebar height and the overall riding position.
A lower handlebar position may suit cyclists seeking a more performance-oriented road setup, while a higher position may be preferable for riders who want a different balance of reach and comfort.
The resulting handlebar position also depends on frame geometry, headset spacers and stem length.
Choosing Between 70 mm and 90 mm
Stem length is an important consideration when adjusting a bicycle's cockpit.
The 70 mm version offers a shorter distance between the steerer and handlebar than the 90 mm version.
Depending on the existing setup, selecting a different length can influence reach, rider posture and steering feel.
The correct choice should be based on the cyclist's fit requirements and bicycle geometry rather than assuming that a shorter or longer stem is automatically better.
For riders making significant position changes, a professional bike fitting can help determine the appropriate configuration.
Compatibility with Standard Road Handlebars
The PRO PLT uses a 31.8 mm handlebar clamping diameter, a common size on modern road bicycles.
It is designed for compatible 1 1/8-inch threadless fork steerers.
Before purchasing, confirm both the handlebar clamp diameter and steerer dimensions. Integrated and proprietary cockpit systems may require different components.
Installation must follow the manufacturer's instructions, including appropriate tightening torque and component compatibility.
A Practical Component for Road Bike Positioning
The PRO PLT stem is particularly relevant for cyclists replacing an existing stem, adjusting handlebar reach or refining their position on a road bicycle.
Its reversible angle and choice of lengths make it useful for cockpit adjustments without replacing the entire handlebar.
The aluminum construction and understated appearance also make it suitable for riders who prefer traditional, serviceable cockpit components.
PRO PLT – Reliable Construction and Adjustable Positioning
The PRO PLT ±6° alloy stem combines AL-2014 aluminum construction, a reversible angle and standard 31.8 mm handlebar compatibility in a clean, functional component.
Available in 70 mm and 90 mm lengths, it provides a practical solution for road cyclists seeking to adjust their cockpit position or replace a compatible existing stem.
