Description

The Park Tool BBT-59.3 Bottom Bracket Tool is precision CNC-machined from aluminium for removing and installing certain 16-notch threaded bottom brackets, including Shimano Ultegra BBR60 and Deore XT MT-800 models.

Manufactured in-house by Park Tool, it is anodised for quick identification and features a 3/8" drive for use with a ratchet or torque wrench, allowing precise tightening to the recommended torque.

Its integrated thread makes it fully compatible with the BBT-RS retaining system (sold separately), which applies constant, adjustable pressure for optimal engagement and to prevent slipping.

Compatible with cups with an outer diameter of 41–42 mm and an inner diameter of 39 mm. Not designed for use with powered impact tools.
