Campagnolo Power and Ultra Torque Bottom Bracket Bearing Tool

Campagnolo's BB system has two flavors that share family DNA but need different service paths. Ultra Torque is the higher-tier system: the two crank arms each carry their own bearing inboard of the spindle, and a center-mounted Hirth-joint coupling sets the spindle's preload. Power Torque is the mid-tier system: a single integrated bearing on the drive side carries the spindle, with the non-drive arm pressed onto the spindle from the outside. Bearing service on either system needs a tool that pulls the bearing without damaging the crank arm.

The 1626A is the Campagnolo-specific service kit. It takes the 1626/2 bearing puller and adds the adapters needed for crank-and-bearing extraction on both carbon and aluminum Power Torque cranksets. The puller's forged arms grip the bearing's outer race without flexing; the tapered edges hold engagement with the bearing throughout the pull, so the bearing comes out clean rather than walking at an angle.

What's in the kit

• Forged-arm bearing puller (the 1626/2 base, sized to Campagnolo Power Torque and Ultra Torque bearings)
• Adapters for crank and bearing removal on aluminum Power Torque cranksets
• Adapters for the same on carbon Power Torque cranksets
• A plastic-bodied install press for setting a fresh bearing in place using a mallet

How the install press works

After the old bearing is out, the new bearing needs to be pressed into the crank arm at square depth. The kit's plastic press accepts mallet strikes on its body without transmitting the strike directly to the bearing's outer race; the press takes the load. The result is a square install on the first attempt, without the side load that direct mallet contact would put on the bearing.

Compatibility

• Campagnolo Ultra Torque cranksets (Super Record, Record, Chorus current generations)
• Campagnolo Power Torque cranksets (carbon and aluminum)
• Fulcrum Power Torque cranksets (Fulcrum is Campagnolo-owned; same Power Torque bearing system)
• Not for Shimano HT2, SRAM DUB / GXP, or other non-Campagnolo BB systems

Specs

• Material: forged arms (premium flex plus carbon steel), heat-treated for tensile load
• Bearing puller geometry: tapered edges for secure engagement during extraction
• Crank adapters: sized for both aluminum and carbon Power Torque cranksets
• Install press: plastic-bodied, mallet-compatible
• Includes: the bearing puller, crank/bearing adapter set, install press

Built in Zreče

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 1626A is the Campagnolo-system service kit that took the dedicated bearing puller and bundled the crank-extraction adapters around it; a workshop that services Italian road bikes regularly runs through enough Campagnolo bearings to make the bundled tool the right call over the bearing puller alone.

Pro tip from our mechanics

Campagnolo's Power Torque non-drive arm is pressed onto the spindle from the outside; the bearing on the same side spins on the spindle without the press-fit relationship the drive-side bearing has. When the BB starts creaking on a Power Torque setup, check the non-drive arm's seating before assuming the bearing is the source; a loose press-fit on the non-drive arm is a frequent creak cause that the kit's adapters can pull and reseat, often without replacing the bearing at all.
