SKS TOM 7
This may be the best mini-tool ever. It includes
a 6mm hex key, a T25 torx, a Phillips #1 screwdriver and 2–5mm hex keys. At just 88 grams,
the Tom 7 is compact and lightweight and comes
with its own neoprene cover. Realistically, the
Tom has every tool you’ll need to make simple
mid-ride adjustments to your bike.
This cool digital air-pressure gauge
works on both Schrader and Presta valves
and measures pressure in psi or bars up to 10
bars or 144 psi. The head rotates for easy positioning, and the digital display is backlit. There’s an auto switch to turn
off the unit if you forget to save the battery. It’s small enough to carry
with you, and especially useful if you ride in places or conditions that
might require changing tire pressure, and it even has a deflate button
that opens the valve to make it easy to deflate to a precise pressure.
The gauge sells for $25 and comes with a battery.
