A new standard in bottom bracket performance is HERE!
Welcome the newest member of the SLF Motion family of products - our new Hyper Bottom Brackets. In continuous development for over a year, we are excited to release what we feel is the smoothest, fastest, and most durable complete bottom bracket in the Industry.
All Hyper Bottom Bracket are each hand assembled at SLF HQ in Pawnee, Illinois USA. Our chosen silicon nitride balls are produced right here in the USA and provide benefits such as being 58% lighter, 121% harder, and 68% stiffer than more traditional steel alloy balls. All Hyper Bottom Bracket bearings are "coated" to ensure maximum performance and provide longer term durability.
BB90 - Our BB90 Hyper Bottom Bracket set includes 2 "Ready To Install" bearings, 2 Bearing Covers/Reducers, and the required liquid "locker" for direct press-fit into frame. Our BB90 Hyper Bottom Bracket set is for use with Shimano 24mm spindle cranks only.
BB90 Hyper Bottom Bracket ships with:
2 BB90 pre-lubricated "ready for direct frame press" bearings
