We got ahold of the new F-15 tool back at Sea Otter and have been using it as much as possible since then…True to form, Crank Brothers took an unconventional, yet sleek approach to this multi tool. With their M-19 already being one of our all time favorite multitools, it’s got big shoes to fill…This tool is essentially comprised of three pieces: a standard folding multi tool, a forged chain tool/spoke key and a brushed aluminum sleeve with a magnet that holds it all together.

Everything pulled apart and opened up. The only thing you can’t see in the picture is the bottle opener on the other side of the sleeve.

The F-15 is definitely not short on features as it’s got just about every fitting that a mountain biker could require for common trailside fixes. In fact, for the most part it shares a great deal of the same tools as the M17 and M19, it just takes a different approach…More on that below.

In Use

Initially we were a bit concerned about how tiny the foldable set of keys are, but after watching a video on Crank Brothers site we had a “why didn’t I think of that?” moment. As you can see in the photo below, you can use the sleeve to provide extra leverage. Having actually bent/twisted other multi tools in the past while trying to remove pedals – we think this is not only much easier on your palms, but it makes trailside crank/pedal removal much more realistic. Additionally, the same approach can be used with the chain tool and even with the spoke wrench if need be.

Speaking on overall quality, the finish on all of the tool bits is extremely hard and their durability has been excellent. As for the foldable set, the bits stayed snug for long periods of time without rattling loose. We feel this is largely thanks to the plastic washers on each end of both rows. In the event that they start to come loose, they can be snugged up with two 3mm allen keys.

Overall

All in all the F-15 is a great tool. Our one gripe is that the forged chain tool makes it a touch heavy on one end. It’s about 50g heavier than a Birzman with similar features; ironically we bent that tool. With that said, the F-15 chain tool itself is much more solid than most you’d on most multi tools – after all, it is forged steel. Besides, if the chain tool is a turn off and/or you wanted something slightly more compact, Crank Brothers also offer the F10+ and it is about 50g lighter.

Compared to every other multitool on the market, the F15’s major advantage is the fact that you can use the aluminum sleeve to get loads more leverage (and open beers with) So…the F-15 is sleek, highly functional and while not freakishly light, it is super practical and very durable. All in all, it’s a great tool especially if you’re the type of rider who often does a great deal of trailside fiddling…
