In its collection of 20 tools, the Lezyne CRV offers 2, 2.5, 3, 4, 5, 6 and 8mm Allen keys but no 10mm. Flat and Phillips screwdrivers are here as well, along with a T25 Torx wrench.
There's also a combined tyre lever and 10mm open-ended spanner, plus a disc brake pad separator/bottle opener combo. The large chain tool has Mavic, 3.22 and 3.45 metric spoke head slots. Unusually for a bike tool, the CRV 20 also has a serrated 2¼in blade.
At 88mm x 53mm x 20mm, the tool has a long body, which makes it a great choice for bigger leverage jobs like removing a sticky pedal or retightening a loose crank arm. Because the chain tool is fixed it can be a little awkward to use; it’s fine in an emergency situation but we wouldn’t recommend it for workshop use.
The 3mm Allen key is fixed, which meant we had to find a spare one when the CRV20’s bolts started to loosen. The multi tool comes with a Neoprene wrap to hold everything in place when pocketed and give you protection from any spiky bits.
Build quality is excellent, with thick, forged aluminium side plates. The individual tools are hardened and we haven’t managed to chew any of the ends up yet. They’re also corrosion resistant, providing you give them a squirt of WD40 or the like now and again.
