Bontrager XDX tyres review
Bontrager’s massive new tyre adds ﬂoated comfort and predictable drift, but the vast carcass means you need at least a 28mm rim to keep it stable, and it’s too wide to ﬁt in a lot of bikes.
All this air space gives it a remarkable amount of cushioning against impact punctures or general trail discomfort. You also get 29er-style rollover on rocks and roots.
A tight, tubeless-ready bead means you can run it soft with a tube or sealant for extra ground-moulding grip from the dual compound mixture.
It clears fast and there’s lots of rubber on the trail, so grip isn’t bad either, although it’s deﬁnitely a drifter rather than a directional tyre. It will tear apart if you skid too much though.
