Core Benefits & Use Cases

• Customized Ergonomics: The pivoting joint allows riders to easily raise the handlebar for an upright, back-friendly posture or lower it for a sportier, aerodynamic profile.
• Universal Fitting: Natively locks onto standard modern 31.8 mm bars, but the inclusion of sizing shims makes it backwards compatible with older 25.4 mm traditional handlebars.
• E-Bike Compatible: Its robust forged construction makes it strong enough to handle the extra weight, vibrations, and frame stresses common to urban commuter eBikes and hybrids.
