You’re seven miles up a narrow valley and nearing the welcome end to hours of steady climbing when you hear a sharp thwack, followed by a hiss — your front tire has just gone flat, you don’t have a spare and there’s no cell service; you do not want to be here.
Next to everything else that might go wrong with a bicycle on an extended ride, a flat is a relatively minor issue that can be easily repaired trailside, if the right tools are at hand. If they aren’t, a quick fix can turn into a long walk. Well-prepared riders will perform a tune-up regularly and clean their bikes after every ride. For the less-diligent, a well-stocked repair kit will suffice.
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.
That preparedness went a long way; she and her riding partner, Huyen Nguyen, completed the 1,200 miles of rough road and only had one repair: a flat tire.
Even though she didn’t have to use it frequently, the repair kit was there. “I really honed in on the way I was carrying stuff and what I was bringing,” she says. “It forced me to dial in my kit. I’ve taken what I used there, and what I learned there, into my next adventures.”
Those adventures run the gamut from a self-supported 300-mile bikepacking race in Arizona to the hours’ long rides accessible from her doorstep in Ketchum, Idaho. The repair kit is a constant, and it doesn’t change much even when the distances differ: “It’s pretty much the same each time around,” says Rusch.
