A machined bottom bracket socket for Shimano's dual-sided cup design, with a centre nub that engages the crank spindle for a second point of contact so the tool can't cam off the cup.

Highlights

  • Machined (not cast or forged) for a precise, non-marring fit on anodised cup surfaces
  • Centre nub matches the crank spindle diameter for a second contact point that resists cam-out
  • 3/8 in square drive for a ratchet or torque wrench
  • Machined in Bend, Oregon, USA

Why machined, not forged

Forging is stronger but less precise; machining holds tighter tolerances so the tool doesn't chew up anodised bottom bracket cups the way a loose-fitting cast socket can.

Compatibility & fit

Designed for the Shimano Dura-Ace BB93/DA-9000 and XTR BB93 bottom brackets, and for Ultegra 6800 and 105 5800 11-speed groups (BBR-60). Not compatible with earlier 10-speed Shimano bottom brackets.

Abbey Bike Tools doesn't publish detailed consumer warranty terms for this category, though it stands behind the precision of its US-machined tools — for warranty support, return the product to Tune Cycles and we'll manage the claim with Abbey Bike Tools' Australian distributor.
