Cycle rear suspension with shock absorber built into frame lug

摘要

A frame having rear suspension system for a two-wheel cycle such as a bicycle or motorbike. The suspension system includes a tubular shock absorber whose outer tubular housing is integrated into a cast or machined lower lug. Several of the main frame tubes and the pedal shaft bearings are also mounted to this lug. By integrating the outer tube of the shock absorber into the tube junction lug, a substantial savings in weight and components is obtained in the chassis assembly while still providing a suspension system.
