Bike Tool Set in Tool Tray — Bottom Bracket, Spoke & Brake Tools (1600SOS26)

Three drivetrain-adjacent service categories share a single workflow: bottom-bracket removal, spoke truing, and disc-brake piston work. They’re not the same job, but the tools cross-pollinate often enough that bundling them into one tray saves drawer-finding time on every related service. The Unior 1600SOS26 tray covers all three: 18 tools for bottom-bracket socket fitment, wheel spoke service, and disc-brake piston spread.

What’s in the tray

Bottom-bracket sockets (covering nine modern BB patterns):

• BB30 & DUB removal tool (1625/2 80); BB30/PF30 and SRAM DUB cup removal.
• BB90 removal tool (1625/2BB90); Trek BB90 press-fit cup removal.
• Bottom bracket socket 16-Notch (1671.16N); Shimano Hollowtech II 16-notch.
• Bottom bracket socket 8-Notch + Bosch Gen 3/4 lockring (1671.2/4); Bosch e-bike motor lockring and 8-notch BB cups.
• BB sockets BB9000, BBR60, BSA30, MegaEVO, T47 (1671.BB9000, 1671.BBR60, 1671.BSA30, 1671.MEvo, 1671.T47); the five additional BB-cup spline patterns covering current Shimano, Praxis, T47, and BSA30 standards.
• BB socket retaining tool (1671.RET); holds the socket in alignment during high-torque removal.

Wheel spoke service:

• Spoke wrench (1630/5); multi-size 3.3, 3.45, T20, 4 mm.
• Flat spoke holder (1632); for aero/bladed spokes that need rotational holding while the nipple turns.
• Pro spoke wrench (1633/2P-US); 4 × 4.4 mm and 3.3 × 3.45 mm double-sized.
• Double-sided spoke wrench (1636/2P-US); 5.5 × 6 mm.

Tire service:

• Set of two metal tire levers (1657/2A); heavier-duty levers for stubborn beads.
• Set of two tire levers, red (1657RED); plastic levers for everyday tubeless and clincher work.

Disc-brake service:

• Rotor truing fork 2.0 (1666/6); 2.45 mm slot tolerance, hardened tool-steel construction.
• Disc brake piston spreader (1750/2DP-US); for caliper alignment and pad service.

Why these tools share a tray

The decision to put BB sockets, spoke wrenches, tire levers, and brake tools together looks unusual, but the service workflow it serves is the bench mechanic’s “set up a wheel” workflow: remove the rear wheel from a parked bike → remove cassette (with 1600SOS25) → true the wheel → re-install the cassette → adjust the disc-brake caliper. Half of that workflow lives in this tray (the wheel-truing and brake half), the other half in the 1600SOS25 drivetrain tray. Pull both trays, do the service, slide both back.

Companion trays in the modular series:

• 1600SOS21; Hanger Alignment & Cable Pliers
• 1600SOS23; Sockets, Ratchets & Torque Wrench
• 1600SOS24; Cone Wrenches
• 1600SOS25; Crank, Cassette & Freewheel Tools
• 1600SOS27; Hex/Torx T-Handles & Screwdrivers

Compatibility

Fits the full-width drawer slot in Unior’s tool carriages: Hercules, Eurovision, Eurostyle, Euromotion, and Europlus.

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 Rotor Truing Fork 2.0 (1666/6) in this tray is the same laser-cut, heat-treated tool-steel construction Unior uses across the pro disc-brake-tool line; workshop-grade fitment, not consumer-grade.

Pro tip from our mechanics

The 1600SOS26 is the tray most likely to be pulled alongside the 1600SOS25 drivetrain tray. For shops that run wheel truing and brake adjustment as part of their service-ticket flow, the two trays together cover the back-end of a complete tune-up.
