Why Carry Tools
A flat tire 20 miles from home with no tools is a long walk. 90% of roadside mechanical issues can be fixed with 5 basic tools that fit in a jersey pocket. Being self-sufficient is a fundamental cycling skill. Pair tools with proper safety gear.
Essential Tools
- Multi-tool — hex keys, screwdrivers, chain breaker
- Spare tube — correct size for your wheels
- Tire levers — 2-3 plastic levers
- Mini pump or CO2 inflator
- Patch kit — backup for the spare tube
This entire kit weighs under 400g and fits in a saddle bag or jersey pocket.

Flats are the most common roadside issue. Know how to fix one before you need to.
- Remove wheel, unseat tire with levers
- Remove tube, check tire for debris
- Install new tube, partially inflate
- Reseat tire, fully inflate
- Total time with practice: 5-10 minutes
