ABSTRACT:
An improved cantilevered-beam seat particularly suitable for a tubular-metal bike-frame, wherein the essential generic TitanFlex.TM. embodiment includes four generic variances. The first embodiment comprising a titanium-frame, having an integrally-formed cantilevered tubular-beam projecting aft from top of head-tube, which length and intermediate fulcrum-stanchion are tuned to deliver a fixed degree of deflection for an average rider whose seat is adjustable fore/aft thereto. The second version embodies the same structure, wherein is provided a special concealed carbon-fiber dampener-tube having a finely tapered trailing-end, fitted within the titanium beam; -lending a suitable amount of resonate-dampening to the natural cantilivered-beam springiness. The third version adding a special ASAP (adjustable shock-absorption platform) DialRide.TM. device; enabling rider to advantageously fine-tune the longitudinal spring-rate position of the previously mentioned internal dampener-tube, -on-the-fly. A forth version embodying the latter mentioned system, with added advantage of a frontal pivot-anchor for the titanium cantilevered-beam in combination with inter-swinging slip-fit stanchion-tubes, -enabling seat-height adjustment to cyclist's leg-length, also permitting entire main-frame to be made of much less costly cromoly-steel.
