With a little knowledge, you can usually fix most malfunctions right at the side of the road, as long as you have some basic know-how and the right wrench. While it's entirely possible to simply carry a handful of full-size tools with you on every ride, most cyclists opt for some sort of cycling-specific multitool.
|Some of the multitools in my collection. From left to right: Topeak, Wrench Force, Crank Brothers and Park Tool.|
|Allen wrenches, box wrenches, spoke wrenches bottle opener, screw driver, tire levers, chain tool and knife blade... I may have missed something.|
Most riders are perfectly fine with a smaller, less expensive tool, such as the Wrench Force tool I also have.
|All the Allen wrench sizes you're likely to need, plus a philips and flatblade screwdriver.|
If you're anything like me, you'll probably accumulate a few of these tools over time, and if you own more than one bike, will likely have a tool kit for each. In my case, the inexpensive tools usually stay with the commuter bike, that's locked outdoors, while the more elaborate tools go with me on longer recreational treks.
Unless I'm leaving the bike locked up in a high-risk area, my multitools usually live in a saddlebag, often with a spare inner-tube, portable pump and other accessories.
