Wheels Mfg BSA 30MM Bottom Bracket
The Wheels Mfg BSA 30MM Bottom Bracket is a BSA bottom bracket designed for 68 mm shells. This shell width is most commonly used for road bikes. The cups are machined from aluminum and held to strict tolerances. This helps eliminate bottom bracket creaks and a sleeve is used to protect your cables and hoses from your spindle. This bottom bracket is designed for 30 mm spindles. It is available with ABEC-3, Angular Contact and ZERO Ceramic bearings so you can select a balance of durability with performance.
Wheels Manufacturing Bearing Differences
The Wheels Mfg BSA 30 mm bottom bracket is available with three different types of bearings. ABEC-3 is designed as an OEM replacement. This is the best balance of cost and durability. Angular Contact bearings provide better durability and are designed to last longer, but are more expensive. Zero Ceramic is Wheels Mfg highest quality bearing and has the least amount of drag. They are made to be as fast as possible which also means they have a lower durability rating.
