19" Impact Gravity Pro Trials Unicycle - White (32mm)
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 Sylph unicycle)
This unicycle is available with both 32mm (Gravity Pro) and 42mm bearings (Gravity).
– 32mm bearings are Impact’s performance bearing, providing a dramatic decrease in weight, as well as added stiffness. As a performance product, these bearings require maintenance and have a shorter life than 42mm bearings.
– 42mm bearings are used on almost all mid-professional tier unicycles. Although heavier than 32mm bearings, these bearings offer reliability and increased compatibility for other brand’s frames.
