Just found this in a box of bits I'd forgotten about. I'm not sure which model it is but it has air cartridges at the top of the right leg and at the bottom of both. All seem to work fine still but the lockout cable on top of the left leg is broken so no lockout unless you get them serviced. Clamp on canti bosses. Magnesium dropouts. Bolt on crown. 1in alu steerer (210mm). 80mm travel. £70 posted, including perfect 1in Synchros headset.
