Beside the reconditioned cam followers, BBT has also several new cam followers in stock. The outside of the level of a cam follower should be curved with a radius between 1,4 and 2,1 metre. After a long period of use, the radius will become straight or even negative. For correct mounting, its important to use cam followers with a correct radius. So you avoid early wear and tear.
