Professional mountain biker Rebecca Rusch has been on plenty of long rides and experienced enough mechanical failures to know what makes a fully-stocked repair kit. One of her recent journeys, a 1,200-mile journey through the jungles of Vietnam, Laos and Cambodia along the Ho Chi Minh Trail required the utmost degree of preparedness — “We brought with us a lot of extra bearings, o-rings, stuff that you would never be able to find in Laos and Cambodia. Before I go out on these big adventures, I replace every bearing in my bike, my fork got a total rebuild — everything is in pristine condition,” says Rusch.
Many bikes, including older models and track bikes, have bolts attaching the wheels to the frame instead of quick-release levers. If your wheels are bolted on, in most cases you’ll need a 15 mm wrench to remove it. We didn’t test wrenches, because there aren’t that many tiny 15 mm wrenches, but the GearWrench 15mm 12-Point Stubby Combination Wrench is perfect for stuffing into a flat kit and Amazon reviewers seem to think the same. Our experts also recommended the Surly Jethro Tule, but it’s expensive and harder to find.
Now you might be wondering: “I’m carrying a tube; why carry patches at all?” As insurance for the unforeseeable. Wirecutter senior editor Christine Ryan admits she didn’t use to pack them, but said, “I’ve regretted that decision when I’ve had a flat on a ride, used my spare tube, and then, half an hour later, had a second flat. Also, lots of people aren’t very good at figuring out—or don’t take the time to figure out—what caused their flat and remove the cause: thorn, eensy bit of glass, whatever. Then they promptly have a second flat, and everyone else laughs at them.”
Unlike floor pumps, most hand pumps do not have pressure gauges. To get readings during my original round of testing for this guide, I built a special rig involving simple hardware-store parts. But the experts I spoke to seem divided on the usefulness of gauges. Half thought they were unnecessary, added bulk, and drove up cost. Why do you need a gauge if you know 100 pumps inflates your tire? But the other half liked them, because the “thumb test” is notoriously inaccurate.
The Pedro’s lever slipped only once throughout testing, though that may have been my fault because I was spaced out after changing 16 different tires. So they’re not foolproof, but they are far and away more reliable than the next closest competitor, from Park Tool, because the small, rounded tip on that one is hard to keep seated under the tire. Not impossible, but I wouldn’t choose it over Pedro’s.

Brakes come in a variety of designs depending on the age and style of your bike. Rim brakes offer more modulation but have less stopping power, so are more suited to riding on the roads. Disc brakes can provide huge amounts of stopping power so are best suited to off road riding, although ‘V’ rim brakes are also well suited to mountain biking. All brakes use a friction system to stop the movement of the wheel, so regular checks of the contact pads should form part of your regular cycle maintenance.
