Enduro 1-3/8" 45 x 45 Degree Stainless Steel Angular Contact Bearing 37mm ID x 49mm OD x 7mm MFPN=724699 Sacrifice nothing - not durabilityEnduro Angular Contact bearings engage all of the bearing's balls to spread the force over a larger surface area minimizing wear and increasing bearing life. This is particularly important in applications like BBs where there are constantly changing lateral loads on the bearings which is typically the primary cause for premature bottom bracket bearing failure.
