Lezyne Carbon-10 tool

The Lezyne Carbon-10 multitool is seriously light yet it manages to pack in most of the key features you need to get home should you suffer a mechanical out on the road.

You know a multitool is going to be expensive when it arrives in its own shiny tin with its name on the top. Open up the tin and you find a sleek-looking object inside...

Those sideplates are structural carbon fibre rather than alloy with carbon over the top, and the bolts are titanium – this thing really is as light as it looks.

The tools themselves are stainless steel, forged and then CNC machined to get rid of any excess weight. They've even removed material from the sides of the Allen keys towards the pivot end where they don't need to be hexagonal. Pared down, then.

You get the Allen keys you're most likely to need from 2mm up to 8mm. The structure of the multitool sits well in your palm to give you a firm hold and you get as much leverage as you'll need for most jobs. That said, you'll struggle to remove stubborn pedals from crank arms (assuming your pedals take an Allen key) and there's certainly not enough leverage with the 8mm Allen key to tighten crank bolts enough to ride far.

You get a couple of Torx (star shaped) screwdrivers here that are less useful in the road world than in mountain biking, although you might have Torx bolts holding your chainrings in place, for instance.

You'd have to say that using the chain tool is pretty fiddly if you have sausage fingers because the parts are very, very small... but how many 80g multitools have a chain tool in the first place? It does work fine.

For most problems the Carbon-10 does a very good job and the tools themselves are tough. I've not managed to round any off yet; not even close.

Of course, if you want something as small and lightweight as this, there are going to be omissions. There's no spoke wrench, for example, so if your wheel goes wildly out of true you'd better have your phone handy. But whatever multitool you pack, there will always be limitations.

All in all, though, this diddy multitool proves to be very functional. The only tricky bit is stomaching the, um, interesting price.
