Bike Tool Set In SOS Tool Tray

Torque specs stopped being optional the moment carbon became normal, and a shop that owns one torque wrench ends up using it for everything from a 1.5 Nm compression bolt to an 80 Nm cassette lockring, which no single wrench does well. The Unior 1600SOS15-US solves that with two electronic torque wrenches covering the low and high bands, then fills the rest of the tray with the drivers, sockets and keys that feed them. At 48 pieces it is the largest tray in the legacy SOS series.

What's in the tray

Torque:

• Electronic torque wrench (1/4" drive, 1–20 Nm); the low band, for stems, seat clamps, lever hardware and rotor bolts.
• Electronic torque wrench (1/2" drive, 4.3–85 Nm); the high band, for cassettes, cranks and bottom brackets.

Y-wrenches and loose keys:

• Y hex wrench (2, 2.5, 3 mm) and Y hex wrench (4, 5, 6 mm).
• Y Torx wrench (T10, T15, T25).
• Wrench with TX profile and hole (TR10); the security-Torx profile with the centre pin bore.
• Hex wrenches (220/3); 1.5, 2, 2.5, 3, 4, 5, 6 and 8 mm.
• Hex wrenches, long type (220/3L); 10 and 12 mm.
• Ball-end hex wrenches, long type (220/3SL); 3, 4, 5, 6 and 8 mm.

Drive, sockets and bits:

• Reversible ratchet 1/4".
• Swivel handle 1/2" (1/2" × 450 mm); the breaker-bar length for lockrings and crank bolts.
• Sockets 1/4", 6-point; 8, 9, 10, 11, 12, 13 and 14 mm.
• Socket 1/2", 6-point; 15 mm.
• Hex sockets 1/4"; 3, 4, 5 and 6 mm.
• Hex sockets 1/2" (192/2HX); 6 and 8 mm.
• Long hex socket 1/2"; 10 × 100 mm.
• Screwdriver sockets with TX profile, 1/4" (187/2TX); T10, T15, T25, T27 and T30.
• Extension bar 1/4" (1/4" × 100 mm) and extension bar 1/2" (1/2" × 125 mm).
• Adaptor 1/4" (1/4" → 3/8").
• Adaptor 1/2" (1/2" → 3/8").
• SOS tool tray shell for 1600SOS15 (629202, 564 × 364 × 30 mm).

Note that the drive hardware here is 1/4" and 1/2"; the 1/2" ratcheting work is done by the swivel handle and the 1/2" torque wrench rather than by a separate 1/2" ratchet.

Where the 1600SOS15-US fits in the system

This is the torque-and-fastener tray of the legacy 1600SOS13–19 series, and the one most likely to be bought on its own, because the two electronic wrenches are the expensive part of any workshop tooling budget. Its companions:

• 1600SOS13-US; hanger alignment and cable work
• 1600SOS14-US; combination wrenches, pliers and measuring
• 1600SOS16-US; single-sided cone wrenches
• 1600SOS17-US; cassette, freewheel and crank tools
• 1600SOS18-US; bottom bracket, spoke and brake tools
• 1600SOS19-US; T-handles and screwdrivers

T-handle hex and Torx drivers live in the 1600SOS19-US, not here; the two trays are designed to be run together.

Compatibility

Tray shell 564 × 364 × 30 mm, the standard Unior SOS footprint, available separately as part 629202. Check your drawer's clear internal dimensions before ordering.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. Splitting torque across two instruments rather than one is a workshop-accuracy decision: a wrench is least accurate at the bottom of its range, so a 4.3–85 Nm tool asked to set a 2 Nm stem bolt is being used exactly where it is weakest.

Pro tip from our mechanics

If you buy one tray from this series, buy this one, and calibrate the habit before the tooling. The low-band wrench is the one that pays for itself, because the expensive failures in a modern workshop are overtightened carbon components rather than undertightened steel ones.
