Race-ready tubeless tyre system from Hutchinson, £54.99
At 265g its 30g lighter than the Fusion 3 and not miles off the pace for a high-end tyre.
We've been impressed with the puncture resistance; it's no worse than the best we've used, which is a way of saying it cuts up but not without reason. Size wise it comes up small for a 23mm tyre and measures more like 21mm, making it more aerodynamic and, thanks to the tubeless construction, pinch resistant too.
The final words are saved for the ride characteristics. Atom tubeless are simply brilliant. On last year's Etape, the low rolling resistance was a joy while the confidence-inspiring feel when cornering was simply astounding.
In my opinion, the Atoms are the best tyres for cornering performance and grip.
