[Closed] bearing code for shimano external BB???

endura bearing 2437

61805 2RS from a bearing supplier.(some BBs have a slighly narrower bearing, 6mm not 7mm, apparently not available).

As Coatesy say earlier models have a smaller width bearing so the shield won't fit the bearing code listed above. Though I suppose if you remove the inner lip once fitted they can't go anywhere. The endura bearing fit without out a shield that fits within the bearings, so have potential to damage the axle if the seize & you keep in riding ( axle can spin within the bearing causing wear).
