The bottom bracket is one of the hardest working parts on a bicycle. It has to endure countless miles of repetitive use whilst being exposed to a variety of weather conditions. This is why we created the ÆRA No. 1 bottom bracket, offering the very best UK designed and manufactured component to ensure that all of your effort is transmitted as efficiently as possible through to the drivetrain whilst also creating a beautifully styled and machined part that complements your bicycle perfectly.
Optimised to sit perfectly flush with J.Laverack’s Streamline bottom bracket shell design, but also suitable for any other frame, this bottom bracket also features a central sleeve which ensures that there is a barrier between any brake or gear cables and the spindle / axle of the chainset.
Available with steel bearings as standard or ceramic bearings as an upgrade.

Each ÆRA No. 1 bottom bracket central sleeve features a short tribute to the company that originally invented the BSA standard back in 1880’s.
“BSA” is short for Birmingham Small Arms, a British company whose core business was manufacturing light weapons. BSA moved into the bike business during the1880s as bicycles and cycling began to become popular in the lead up to the 1890s bicycle boom. The company continued to make bicycle components well into the 20th century, so the term “BSA” stuck.
