1x 3903 Enduro DR AC Radial Bearing
3903 LLU - Double-Row, Angular-Contact Bearing - 17mm x 30mm x 10mm
Primary application for this bearing is for older square-taper BBs. The double-row design greatly reduces flex in BB spindles and doubles the bearing contact area, while requiring roughly 25% less width than two single-row bearings. This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, LLU seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.
Static load - 1214lbf / 5.1kN Weight - 25.9g
Contains a high quality, durable and long lasting 3903 Enduro DR AC bearing to keep your mountain bike performing at its very best!
