Wheels Manufacturing BBRight Direct Fit Bottom Bracket

The BBRight Direct Fit Threadfit system for the BBright 79mm wide asymmetric 46mm ID PressFit shells basically eliminates the creaking issues PressFit bottom brackets frequently have. Finely machined, and featuring two bearing carrier sleeves, the sleeves act as cups and thread together internally. A 16 notch, 48.5mm diameter tools is required. The Enduro ABEC-3 bearings have low friction, with long life. The bearings are steel, sealed, and reliable. Over time, incredibly cost effective, smooth running and easily (though rarely ever) replaced. Spacers are included for the option selected. Available in 24mm (Shimano) spindle fit and commonly used on Cervelo bikes, this is the best option for most direct Shimano crank installations for BBright.
