Primary Discipline: Trials
Secondary Disciplines: Street, Flatland

This is the latest generation of Impact Unicycle, combining the newest iteration of their famous Eiffel cranks, undrilled rim, and innovative hydroformed aluminium frame that not only looks great but provides one of the stiffest and most agile rides on the market.

The Gravity’s round crown and 140mm cranks make it an ideal trials unicycle, but is equally as at-home as a street or flatland machine, particularly when paired with Impacts 130mm Groovy cranks, or 118mm Eiffel cranks. (Riders wishing to ride trials and do tricks using the frame should consider the Impact Reagent unicycle)
