The THM Clavicula SE crankset is globally regarded as one of the most advanced full-carbon cranks ever produced, featuring a one-piece carbon arm and axle construction. Its patented carbon-to-carbon spline interface offers near-zero wear, silent operation, and exceptional torsional stiffness for maximum power transfer.
Paired with the Carbon-Ti X-CarboRing 53/39T (BCD130×5) chainrings—crafted from structural 3K carbon fiber, AL7075-T6 alloy, and Grade 5 titanium pins—this bundle delivers outstanding stiffness-to-weight performance and remarkably smooth shifting.
This elite combination is engineered for riders demanding the highest possible performance in weight reduction, drivetrain efficiency, and craftsmanship.
