Birzman 7pc ratchet wrench set



Good value, well-made set of tools to grace the cyclist’s home workshop.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

If you’re the sort of person that gets excited about bike tools (not as much as you get excited about bikes, obviously, but almost) then you might know of tool manufacturer Birzman. Fairly new on the scene, Birzman claims to make tools with shapes inspired by nature, and the range is impressive, with all sorts of kit from slinky little mini-tools for emergency side-of-the-road repairs to hefty spanners for the workshop. Sorry, for the ‘StudioCycle’, as the Birzman website trendily has it.

So today we’re testing something from the workshop, er, StudioCycle end of the spectrum: a 7-piece ratchet set comprising the ratchet wrench itself plus six sockets. But not your run-of-the-mill sockets. Oh no. These are dedicated bike sockets.

You get two Shimano sockets - between them handling bottom brackets, cassettes and freewheels - and one for Campag cassettes, plus two hex sockets (8mm and 10mm) for BB bolts or pedal axles.

In their charcoal chrome, they look sexy, but do they work? Yes. The sockets slot nicely onto the cassettes in the test lab, with the splines just right - not too tight and no sloppiness. The sockets also fit snugly onto the wrench itself, and they won’t fall off thanks to a neat locking device.

The wrench handle itself is sturdy enough, reassuringly heavy in fact, although the little switch to change the ratchet direction seems a bit flimsy by comparison.

Full-time professional mechanics are very demanding on tool quality but we haven't seen anything to suggest that this kit is going to fall apart any time soon. For the rest of us, changing cassettes only a few times a year, rather than every day, these tools will definitely do the job.

Retailing at £45 for the set, this is good (though not stunning) value, and much cheaper than buying the items individually. Of course, if you had a socket wrench already and needed just one Shimano cassette remover for example, it would be cheaper to buy this single item on its own.

Birzman tools are distributed in the UK by Merida, and they're available in decent bike shops across the land.

The Birzman website says this: "Birzman tools are inspired by a desire to solve cyclist’s problems simply and effortlessly. Drawing inspiration from nature with their multi-award winning product designs, their aim is to develop only the finest tools, that are both Simple, Functional and Useful." While the shape of some Birzman tools may look like a praying mantis or another rainforest resident, I'm not so sure about this socket set. It looks like a, er, well, like a socket set. But the last bit of the blurb is fair enough; these tools are indeed simple, functional and useful.
