Seat Arm, vertical - 10 cm (4")

The vertical Seat Arm moves a seat 10 cm clear of its mounting point. Both bores stay vertical through the crank, so the seat drops onto a 25 mm connection pin however far you offset it, and a star knob locks each end. Also available in 20 cm and 30 cm. Machined from high-grade aluminium and hard-anodized in Germany by Grip Factory Munich.
