Cycling is one of the most popular hobbies among Germans. Learned from an early age, the bike accompanies many people throughout their lives. As long as the tires are rolling, the brakes are gripping and the rear derailleur is purring, the bike is your best friend on the way to work or in your free time. It becomes uncomfortable when the bike is stubborn. Crawling in the hose, creaking chain, dragging brakes, stuttering rear derailleur? That happens sometimes. Especially in autumn and especially when the bike is in constant use. Two check-ups a year at your trusted bike shop may cost money, but if in doubt you’ll save yourself a lot of nerves. If it catches you on the road, the good advice does not necessarily have to be expensive. Bicycle multi-tools are a small but practical investment that have saved many an unnerved roadside biker from worse. You can find out which tools are available and what they can do in our small comparison.

Multi hits the nail on the head with the Lezyne Rap II 25. The bike multi-tool from the Americans has 25 powerful functions. Including an adapter for a CO2 cartridge. This is by no means standard. However, it is also a function that everyday cyclists are most likely to be able to do without. Every little screw on the bike can be loosened and tightened with the seven different Allen keys and three Torx bits (T10, T25, T30) as well as a Phillips and flat-head screwdriver. Even chain damage can be repaired yourself with the Rap II 25 chain tool and some skill. The bonus tool on this mini tool is not for the bike, but for the pulley. Lezyne has integrated the bottle opener into the safety wedge for disc brakes. Here’s the Lezyne Multi Tool Rap II 25.

The Crankbrothers take part in our little bike multitool comparison with their Multi 19. When it comes to weight, the French are on par with the Lezyne tool. Anyone who can do without a CO2 cartridge will still find a high-quality, but somewhat more expensive alternative in this tool made of Hi-Ten steel. Loose spokes can be tightened with it, as can all other safety-relevant nuts and screws on the rear derailleur, brakes, saddle, handlebars and cranks. Beautiful: The Multi 19 from Crankbrothers is available in black/red, midnight, gold and in the classic nickel look. All in all a basic tool for mountain bikers, racers and e-bikers alike. Here’s the Crankbrothers M19 Multitool.
