Description
Promax MQ-579-BK
The Promax MQ-579-BK is a high-quality, adjustable quill stem made of robust aluminum, specifically developed for city, trekking, and urban e-bikes. With a quill diameter of 25.4 mm, an extension of 110 mm, and a comfortable quill length of 180 mm, this stem offers maximum flexibility for the ergonomic alignment of the handlebar. The matte black finish blends subtly and elegantly into modern e-bike designs.
Thanks to the stable joint, the angle of inclination can be adjusted in no time at all to achieve either a sportier or an upright, back-friendly riding position. Due to its precise manufacturing and the high clamping force of the joint bolt, the stem remains permanently stable and torsion-resistant, even under the increased loads and vibrations of e-bike rides. Optimally suited for retrofitting or replacement on classic threaded forks.

-

-
