Kit contains 6 Full Complement bearings and 2 Steel Cage bearings for Trek Session 8 (2021-2022) Suspension Pivots.

Full Complement (FC) bearings are designed for use in the short rotations & high loads of suspension pivots.  Where a normal caged bearing contains bearings with space between them and a cage to hold them apart, FC bearings are packed completely full of balls.  This gives greater contact area and makes these bearings last longer than standard caged bearings in suspension pivots.

This kit contains some double row bearings which are not Full Complement (FC) but still feature twice the ball count as a conventional caged bearing for extra strength and durability.
