Quick answer: you need two kinds of tools: a compact multi-tool with a chain breaker for the trail, and a home tool kit for maintenance. On the trail, carry a multi-tool with 2–8 mm hex keys, a T25 Torx, a chain tool and a quick link. At home, a good starter kit adds a torque wrench, cassette and bottom-bracket tools, cable cutters, tyre levers and a chain checker.

Trail multi-tool checklist
- Hex keys: 2, 2.5, 3, 4, 5, 6 and 8 mm
- Torx T25 (rotor bolts and many modern bike parts)
- Chain breaker and a spare quick link
- Flat and Phillips screwdrivers for derailleur limit screws
- Spoke keys (optional)
- Tyre plug tool (some multi-tools hide one inside)
Home tool kit checklist
| Tool | Used for |
|---|---|
| Torque wrench (2–15 Nm) | Carbon parts, stems, bars, brakes |
| Cassette lockring tool and chain whip | Removing cassettes |
| Bottom-bracket tool | BSA and other BBs |
| Cable and housing cutters | Gear and brake cables |
| Chain checker | Knowing when to replace the chain |
| Pedal wrench (15 mm) | Pedals without hex fittings |
| Tyre levers and floor pump | Tyres and tubes |
| Bike stand | Makes every job easier |
What to look for in a tool kit
- Hardened steel (chrome-vanadium or S2) tools that won’t round off bolts
- A sturdy case so you can find tools easily
- Tools that match your bike’s standards (e.g. DUB or Shimano BB, Micro Spline or XD cassette)
- A multi-tool small enough to carry every ride
Our picks
We chose these for the range of tools, build quality and value. Larger kits from BIKEHAND, Odoland and similar brands give home mechanics most of what they need; compact multi-tools such as the Sierra fit in a pack or frame mount. Over time, add quality individual tools (torque wrench, cassette tool) as you take on bigger jobs.
