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: each crank arm carries its own half-spindle with a cartridge bearing pressed on next to the crank, and the two half-spindles join at a center Hirth-joint coupling secured by a 10 mm fixing bolt. Power Torque is the mid-tier system: the 24 mm spindle is integrated with the right crank, the drive-side bearing presses onto the spindle, the non-drive bearing sits integrated in the left cup, and the left arm mounts on spindle splines with a 14 mm fixing bolt. 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. For bearing extraction, the universal puller works together with the bearing removal extension: the extension hooks the bearing itself, and the puller's center spindle, turned with a 19 mm wrench or ratchet, drives the pull.

What's in the kit

• Universal bearing puller (the 1626/2 base, sized to Campagnolo Power Torque and Ultra Torque bearings)
• Three thin plate protectors for aluminum crank arms, plus the pin extension for crank pulling and the bearing removal extension for bearing work
• A thicker plastic protector for carbon crank arms
• The bearing installation tool, which seats a fresh bearing with hammer taps on the tool body

How the install press works

After the old bearing is out, the new bearing needs to go back on square. The bearing installation tool fits over the crank spindle and drives the bearing on with hammer taps on the tool body, so the strikes land on the tool rather than directly on the bearing itself.

Compatibility

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

Specs

• Material: trivalent chrome plating (Cr3+), backed by Unior's lifetime warranty
• Bearing puller geometry: two-arm universal puller driven by a center spindle, turned with a 19 mm wrench or ratchet
• Crank adapters: thin plates for aluminum crank arms, a thicker plastic protector for carbon arms
• Install press: fits over the crank spindle, driven with a hammer
• Includes: universal puller, bearing removal extension, bearing installation tool, carbon and aluminum protector plates, pin extension; 820 g set weight, and every component is available as a spare part

Built in Zreče

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race 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

Two Campagnolo-specific traps are worth knowing at reassembly. Torque matters: the crank fixing bolt takes 42 Nm and the cups take 35 Nm, so set a torque wrench rather than guessing. And on Ultra Torque, check the fixing bolt's thread direction before loosening it: Super Record's titanium bolt threads left-hand while steel bolts thread right-hand, the direction is marked on the bolt, and a magnet settles it when the marking is hard to read, since steel sticks and titanium does not.

FAQ

Which cranksets does the Unior 1626A cover? It services Campagnolo Ultra Torque and Power Torque cranksets, plus Fulcrum Ultra Torque, which shares the Campagnolo system. It is not made for Shimano, SRAM, or any other non-Campagnolo bottom bracket standard.

How does the 1626A pull a crank arm? A protector plate sits between the crank and the bottom bracket cup, thin plates for aluminum arms or the thicker plastic protector for carbon arms. The pin extension goes into the bottom bracket, and turning the universal puller's spindle clockwise with a 19 mm wrench or ratchet draws the arm off.

Can the 1626A replace bearings as well as remove cranks? Yes. The universal puller works with the bearing removal extension to pull the pressed bearing off the crank, and the bearing installation tool seats the new bearing with hammer taps on the tool body.

What torque do Campagnolo cranks and cups take on reassembly? Unior's bicycle mechanics manual lists 42 Nm for the crank fixing bolt and 35 Nm for the cups on both systems. On Ultra Torque, check the marked thread direction before loosening the bolt, since Super Record titanium bolts thread left-hand.
