Crankbrothers M19 vs. M20: Compared

If you’re looking for a reliable and versatile multi-tool for your bikepacking adventures, you might be wondering which one to choose between the Crankbrothers M19 and the M20.

Both of these tools have 19 functions, including hex wrenches, screwdrivers, spoke wrenches, chain tool, and Torx bits. But the M20 has a few extra features that set it apart from the M19.

Tire Repair Features

The main difference between the M19 and the M20 is that the latter comes with a tire plug tool, a tire plug storage case, and tire plugs. This means that you can easily fix a puncture on your tubeless tires without having to carry a separate kit.

The tire plug tool is integrated into the chain tool, and the storage case attaches to the side of the multi-tool with magnets. The tire plugs are made of rubber and have a barbed tip that seals the hole in your tire.

Upgraded Chain Tool

The M20 also has a redesigned chain tool that has more features than the one on the M19. The chain tool on the M20 has a valve core remover, a valve extender wrench, and a second smaller Torx bit (T10). These are useful for adjusting your tubeless valves or replacing them if they get damaged. The chain tool on the M19 only has a spoke wrench and a pin breaker.

Size and Weight

Another difference between the two models is the weight and size. The M20 is slightly heavier and larger than the M19, due to the addition of the tire plug tool and case. The M20 weighs 203g and measures 89 x 55 x 22mm, while the M19 weighs 175g and measures 89 x 51 x 21mm. This might not be a big deal for some riders, but if you’re looking for the lightest and most compact option, the M19 might be a better choice.

Quality and Performance

Both tools have excellent ergonomics, with rounded aluminum side plates and textured grips for security in hand. They also come with a sleek brushed aluminum carrying case that protects them from dirt and moisture. The bits are made from durable high tensile steel that can withstand a lot of torque. Both tools have been tested by many bikepackers and have received positive reviews for their quality and performance.

How to use a Tire Plug Tool?

If you’re wondering how to use a tire plug tool, here are some simple steps to follow:

1. Locate the puncture on your tire and remove any debris or foreign objects that might have caused it.

2. Insert a tire plug into the tip of the tire plug tool until it sticks out about half an inch on both sides.

3. Push the tire plug tool into the hole in your tire until it reaches the base of the tool.

4. Twist the tool slightly and pull it out quickly, leaving the tire plug inside the hole.

5. Cut off any excess tire plug material with scissors or a knife.

6. Inflate your tire to the desired pressure and check for leaks.

Which one should you get?

It depends on your preferences and needs.

If you want to have a tire plug tool integrated into your multi-tool, and you don’t mind the extra weight and size, then the M20 might be worth it.

If you already have a separate tire plug kit, or you prefer to save some grams and space, then the M19 might be enough for you.

Either way, you can’t go wrong with these tools, as they are both reliable and versatile companions for your bikepacking adventures.
