In the race for the title of best compact multitool, Topeak's Hex Mini 20 gets the nod based on its useful tool selection (including chain hook and Mavic spoke key) and the small matter of leaving nearly a tenner in your pocket compared with some of the competition.
The Hex’s tools are all good quality, sharp and well deﬁned for accurate ﬁtting into bolt heads. The chain tool isn’t any easier to use than on other fold-out multitools, but no harder either. If you want better chain tool action, get one with a clip-off chain tool.
In years gone by the Hex’s big brother, the Topeak Alien, bristling with enough gadgets to please a squad of bike-riding SAS troopers, would have been on test, but the feedback we’ve been getting from shops and consumers is that the Hex is a more popular/useful tool.
