Enduro Bearings Deep Groove Ball Bearing B 543 1 9/16" x 2" x 9/32" for Headset

Maximum number of balls for maximum load rating: the B 543 RS2 MAX Bearing by Enduro Bearings

MAX bearings are characterised by a 35 to 40 % higher load capacity than standard radial bearings. Enduro Bearings has been manufacturing them specifically for use on mountain bikes for 20 years. As its name indicates, MAX bearings are fitted with the maximum possible number of balls. The grooves in the treads are deeper to be able to absorb the diverse, rotating lateral forces on MTB joints.
