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 since 1919, and sponsors professional road and mountain-bike race 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.
