My bottle cage starts rattling halfway into a gravel ride. Later, a soft tire leaves me stopped by the trail, digging through my bag for a separate inflator. I'd rather spend the morning riding than let loose bolts and lost air turn it into a walk home.

I'd pack this 9-in-1 tool for the jobs that don't need a workshop. Five hex sizes, T25, Phillips and flathead drivers fold into one body for matching bike fittings. The built-in CO2 head fits Presta and Schrader valves, so I can reinflate after fixing a flat with a compatible threaded cartridge.

Folded down, it slips into a jersey pocket or frame bag, keeping drivers and an inflator together without a bulky repair kit. CO2 cartridges and puncture-repair supplies aren't included.
