Cyclists and bike mechanics, this Wheels Manufacturing BB30 service kit is exactly what you need to get your bottom bracket running smoothly again! The kit includes 2 Enduro 6806 angular contact bearings and 2 retaining clips - everything you need for a complete BB30 overhaul. The dimensions are spot-on at 42mm OD, 30mm ID, and 7mm width, so they'll fit perfectly as direct replacements for OEM systems. The angular contact bearing design is superior to standard bearings because they can handle both radial and axial loads much better, which means longer life and smoother performance. These work with both 68mm and 73mm BB shell widths, covering most modern road and mountain bikes with BB30 standards. The quality is seriously good - Wheels Manufacturing is known for making reliable bike components that mechanics trust. Installation is straightforward if you have the proper tools, and the difference in smoothness is noticeable immediately. No more creaking, grinding, or rough feeling when you pedal - just smooth, efficient power transfer. Whether you're maintaining your own bike or working on customer bikes, this kit provides professional-grade results. Your crankset will spin like butter with these quality bearings!
