Integrated cinch bolt prevents bearing rotation or bind.
Cassette and cinch bolt only, no bearings included.
Available in standard or +/- 6mm offset options.
The standard bearing cassette is factory standard. This means that the bearing sits centered within the body of the bearing cassette.
The +/- 6mm bearing cassette offsets laterally (not vertically) the bearing area in the cassette, allowing wheelbase change +/- 6mm when used correctly.
A longer wheelbase generally stabilizes the kart.
A shorter wheelbase generally 'frees' the kart, making it more responsive.
The offset bearing cassette is also available with slotted bottom holes for certain applications (such as the cassette for the brake caliper).
