Lezyne Blox 23 £29.99
SO GOOD This has the most tools on test and is the only one with 8mm and 10mm spanners. Integrated mechanical stops mean you can apply good leverage on these spanners to get nuts fairly tight. Most of the tools are a whopping 6cm long (excluding the handle), which makes accessing recessed bolts that bit easier.
NO GOOD The Blox 23’s longer tools add extra bulk and weight (200g). The chain tool can get in the way, and the protective neoprene sleeve can be fiddly to get on and off. After minor use, the corrosion-resistant coating began peeling off on a couple of the Allen keys. www.upgradebikes.co.uk
