In this paper we present a new design for a prone position triathlon bicycle frame that is light weight, ergonomically efficient, and requires minimal use of muscles that are used in swimming and running.

The design consists of an aero bar style handlebar, an adjustable noseless seat, crank, chainless drive and gearing system and skeletal support from a hip sling, and armrests
