The Terra Cycles Accessory Mount is for Rans, Bacchetta Giro, and Greenspeed GT3 and is the best system for attaching a light or computer to the front of a short wheel based recumbent bicycle or tadpole tricycle. It is very sturdy and allows the light or computer to be mounted in the center thereby reducing the chance of hitting the light while pedaling. The arms on the clamp are 75 and 100 mm long.
