Set of tools in tray 2 for 2600A and 2600C

Bottom-bracket service and crank service share the same workflow: the cranks come off first, the BB comes out second, and the work is reversed for reinstall. Bundling the BB and crank tools into one tray means the mechanic pulls a single drawer for the workflow rather than two. The SET2-2600AC BB & Crank Tools tray for the Unior 2600A and 2600C workbenches is sized for this combined-workflow purpose; a foam-cut tray dropping into the 990WD7 cabinet integrated into the 2600-series benches.

What this tray covers

The tray is loaded with the Unior BB and crank service tool inventory: crank pullers, crank-cap tools, the full Unior BB socket range covering modern standards (16-Notch Hollowtech II, 8-Notch, BSA30, BB9000, BBR60, MegaEVO, T47, BB30, DUB), plus the master chain tool and chain wear indicator for the chain-and-driveline work that surrounds a crank service.

Tool category coverage:

• Crank cap and crank pullers; for the disassembly side of crank service.
• Bottom-bracket sockets; full coverage across the modern BB standard catalog.
• Pro pedal wrench; for the pedal removal that often precedes a crank pull.
• Master chain tool; for the chain-side work that happens during BB and crank service.

The tray ships with the empty foam shell; replacement shells available separately if the tool inventory shifts over time.

Note on the specific tool list: the per-SKU tool catalog for this tray follows the same content as the SET2-2600AC Drivetrain Tools tray; both trays carry the BB and crank inventory across the 2600A/C bench compatibility window. The differences across the SET2 variant SKUs reflect updates across catalog generations rather than fundamentally different tool sets.

Compatibility

Sized for the bench-integrated 990WD7 drawer in the Unior 2600A and 2600C workbenches. Drops into the standalone 990WD7 wide tool chest for shops running the cabinet outside a bench.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče, Slovenia, since 1919, and is the official technical partner of multiple World Tour and downhill teams. The BB socket range carries the in-house Unior corporate spec phrasing for each cup pattern: 16-Notch covers Shimano Hollowtech II at the 16-notch tool-side engagement, BSA30 covers the BSA30 standard at the 30 mm-spindle envelope, T47 covers the modern T47 BB shell standard. Each spec is corporate-published, not generic.

Pro tip from our mechanics

A BB-and-crank tray is one of the load-bearing drawers in a shop. Crank service is high-volume for any shop running cassette swaps as a recurring service line.
