Praxis Works SRAM DUB BSA 68/73mm Bottom Bracket

Praxis Works’ SRAM DUB BSA 68/73mm Bottom Bracket gives riders a precise and secure way to fit a SRAM DUB crank into a BSA threaded frame, pairing forged alloy cups with steel cartridge bearings for stable support and long-term performance. Its Enduro bearings are built for the 29mm DUB spindle, ensuring smooth load control and a reliable fit across a wide set of road, trail, and DH setups.

Key Features and Benefits

• The dedicated BSA design for SRAM DUB cranks: This layout matches the exact 29mm spindle and thread standard for a precise fit. This reduces flex at the interface, which leads to stable support through long-term use.
• Enduro steel cartridge bearings built for DUB use: These bearings are made to handle the 29mm spindle size and resist wear under load. This improves bearing life, which results in smooth rotation over many miles.
• Forged and machined, heat-treated alloy cups: This construction keeps the BB strong and stable under side loads. This reduces unwanted movement, which maintains alignment between the crank and frame.
• The 29mm drive and non-drive bearing layout: This setup matches the DUB system’s exact bearing spacing. This improves load balance, which helps maintain even wear and consistent spin.
• Wide fit range covering road, MTB, wide, and DH standards: This compatibility allows the same BB to support setups from 68mm road shells to 83mm DH frames. This gives flexibility for different builds, which keeps upgrades simple.
• The need for the Praxis M30 socket or wrench tool: This tool match ensures correct torque during install and removal. This improves fit accuracy, which protects both the BB cups and the frame threads.

The aim of this bottom bracket is to provide a stable and durable base for DUB cranks across a wide range of threaded frames. The steel cartridge bearings offer smooth running over time, while the forged alloy cups hold alignment under load. Its exact match to the 29mm DUB spindle ensures correct preload and consistent support across road, trail, and DH use.

This bottom bracket is a strong option for riders who want a clean and reliable fit for their DUB crank in a BSA frame, with long-term bearing stability and broad frame compatibility providing confidence in day-to-day use.
