Reagent Pro

19″ Impact Reagent Pro Unicycle – Black or White

Primary Discipline: Street, Flatland
Secondary Disciplines: Trials

The Reagent is Impact’s all-round urban unicycle. Featuring a square crown frame ideal for coasting and wheel walk based tricks, this unicycle can also be used for trials and street thanks to its 19” wheel.

Sporting 130mm cranks, this unicycle is ideal for all-round riding, and can be modified with 118mm cranks for smoother flatland lines, 130mm Groovy cranks for flips and rolls, or 140mm Eiffel cranks for Trials. (For pure flatland riding, the Impact Sylph unicycle may be an appropriate alternative)

This unicycle is available with both 32mm (Reagent Pro) and 42mm bearings (Reagent).

– 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.
