Seat Arm, vertical - 20 cm (8")

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