The Crank Brothers tool weighs in at 6 1/8 oz (172g). This widget includes 6 hex keys, 2 Torx bits, a flat bladed screwdriver and a chain tool that has features that look like spoke wrenches and box end wrenches included. The tools in general are low end junk. The chain tool in particular stands out to me. It is clearly designed by some sadist that hates cyclists and takes delight in destroying their gear. The chain tool itself is almost impossible to use since its semi-permanently attached to the multi-tool. You feel like you are working without the benefit of thumbs when you try to repair a busted chain on the trail. Just to add a little sizzle to the whole thing, the designer also threw in spoke
- They're cheaply made.
- They include things you don't need.
- They feel the need to add features like the spoke wrench & box end wrench openings that are so poorly made they only serve to destroy your gear.
- The ergonomics are so bad you can hardly use things like the chain tool.
- They rust ... immediately.
I replaced them with a simple, reversible ratchet driver, specific bits that I need for my particular gear & a Park chain tool. The ratchet, and the five bits (5mm hex, 4mm hex, 2.5mm hex, T10 & T25) weigh 2 3/8 oz (67g). I got the ratchet in the photo from my contacts in the Taiwan / China sourcing work that I do with my job. If your job doesn't require that you take the 1,000 hour flight (coach) to Asia, Amazon carries a few like this for cheap. I'm using Apex brand bits because I can get them easily from work and they're really good stuff. If you go this route, do yourself the favor of contacting an industrial supply house and get high quality tools. Nothing sucks more than cheap tools. Add a Park Tool CT5 chain tool and you have all of the same functionality, significantly higher quality tools, better ergonomics & less weight.
