Enduro Bearings BRT-005 Press Fit Installation Tool
Enduro Bearings' BRT-005 Press Fit Installation Tool is a focused, bearing-friendly driver set designed to protect sealed bearings during Press Fit Bottom Bracket Installation Drivers and Sleeves operations, prioritizing bearing face contact and alignment. It is typically more affordable and lighter than full modular press kits, making it ideal for mobile mechanics or those replacing bearings frequently; while not as feature-rich as a full press system, it minimizes bearing damage risk better than many generic drivers. For teams needing a specialized bearing-safe approach without the expense of a complete press, the BRT-005 is an efficient compromise.
