International ClassB62K 003/00AbstractA pivotless suspension system for a bicycle comprising a shock absorber integral to the frame and an inherently resilient structural member to assist in the suspension system. An adjustable air spring is mounted integral to a seat stay and comprises means for selectably pumping and venting the air spring to increase or decrease ride stiffness. A titanium frame embodiment comprises either a standard or elevated resilient chainstay which acts as the resilient structural member and assists the air spring in the suspension system. A bump driven pump for the air spring; handle bar control of pumping and venting; and a locking means for effectively nullifying the suspension can be provided.Other References
