Carbon parts carry a torque figure, and guessing it is the expensive way · review
The best-selling tool here: a folding 16-in-1 multi-tool with hex keys from 2 to 6 mm (0.08 to 0.24 in), three socket sizes and a screwdriver, at 205 g (7.2 oz).
Our conclusion The default saddle-bag tool. Check whether you need Torx for your rotors before treating it as complete.
ROCKBROS’s 16-in-1 is the best-selling multi-tool in this hub and covers the everyday range.
Sixteen functions: hex keys in 2, 2.5, 3, 4, 5 and 6 mm (0.24 in); sockets in 8, 9 and 10 mm (0.39 in); a flat screwdriver; and a chain tool. Galvanized carbon steel. Ninety by forty-four by twenty-five millimeters, about 205 g (7.2 oz). Stated use for cycling, camping and climbing.
Two to six millimeters is almost every fastener on a modern bike: stem, seat clamp, bottle cages, brake and derailleur bolts. The 8 mm (0.31 in) size, which some crank bolts need, is not a roadside job anyway.
Disc rotor bolts commonly use T25 Torx. A tool without it cannot tighten a rotor bolt that has worked loose, which is one of the more consequential things to find on a ride. Check what your own bike uses.
Galvanized carbon steel is serviceable and it is not chrome vanadium — the STONE REEF in this hub states CrV. On bits that see occasional use and moderate force, the difference shows up as rounding on a stubborn bolt.
A multi-tool cannot generate or measure a torque figure. Use it to get home; check anything with a printed value properly at a bench.
A listing is not an offer: the reference exists on these stores, availability changes daily.

The published function list gives hex 2–6 mm (0.08 to 0.24 in), sockets 8/9/10 mm, a flat screwdriver and a chain tool, without naming Torx. Disc rotor bolts commonly use T25, so check before relying on it for that job.
ROCKBROS states 205 g (7.2 oz) at 90 × 44 × 25 mm (3.54 × 1.73 × 0.98 in) — light enough for a saddle bag, noticeable in a jersey pocket.
