42mm vs 32mm
The Gravity unicycle is now available with both 32mm (Gravity Pro) and 42mm bearing (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 bearing.
– 42mm bearings are used on almost all mid-professional tier unicycles. Although heavier than 32mm bearing, these bearings offer reliability and increased compatibility for other brand’s frames.
Gravity Pro and Gravity
To make sure we can tell the difference between the 42mm and the 32mm Gravity. Impact has started calling the 32mm version the "Gravity Pro". This is the same right across the range, anything with the 32mm bearing gets the "Pro" classification (Gravity Pro, Reagent Pro and Sylph Pro).
Impact are also offering the frames as spare parts, which is great as it will fit many Unicycles that have a 42mm Bearing (Kris Holm, Mad4One, Nimbus).
