Air Bike's Sealed Bearing Threaded BB is a high quality bottom bracket designed for use with all Sram GXP crank sets with a 22-24mm axle diameter. Precision made for durability and smoothness; Air Bike Bottom Brackets keep your bike running creak free and smoother for longer.
Air Bike Low Friction Bottom Bracket
Designed so that the Stainless Steel Sealed Bearings rest on the axle of the crank, these BBs provide a straight load to the bearings, which means your BB will last longer. This also allows us to make the Air Bike Threaded BB with tighter tolerances, so it runs smoother with less friction. This means you'll require less effort to make it up that hill or sprint for the line.
To keep our Threaded BB running smoother for longer, we use special seals that keep water out of the bearings. We use multiple smaller seals, which reduces friction and provides a better barrier against moisture and dirt. Our bearings themselves are manufactured to precision and packed with slick, waterproof grease.
All of the above combine to make the Air Bike Threaded Bottom Bracket the ideal choice for riders who want the best from their bike components.
Three fine-adjusting washers are included to adjust the distance of the chain centre line of the crank piece (3 x 2.5mm spacers to fit 68 & 73mm BB shells).
