Geax Datura TNT 2.2in£24.95

Heavy and skittish for trail work but in its element in the mud

BikeRadar score4/5

A new tread from Geax, the Datura is as straightforwardly grippy as it looks, but with some nice extra features too.

Mid-height knobs in medium compound rubber are well-spaced for soft ground grip and fast clearing. Big buttresses on alternate side knobs make it aggressive through corners and grooves in the knob tops add bite. Add a sturdy TNT tubeless-ready carcass that'll handle low pressures without squelching and you've got a really predictable mucky conditions performer.

It's 150g heavier than the 630g Geax claim though, which makes it a bit hefty for trail work. The central gap tends to tramline slightly too and, like most tall knob treads, it can skate and wander on kitty litter. Decent value.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
