Hutchinson Fusion 5
Hutchinson was the first tyre manufacturer to the road tubeless party, and the latest version from the French company, the Fusion 5, is available in tubeless, tubeless ready and tube versions.
My 25mm pair of the latter incarnation is designed for training and racing in all weathers, and the tyres have a 127 TPI casing with a much-improved Kevlar Pro Tech (Aramid) reinforcement layer.
Their ElevenSTORM rubber compound tread claims to have low rolling resistance, be durable and to be grippy everywhere. They’re light, too, with my pair weighing in at a scant 414g.
When holding the Fusion 5s, it’s obvious just how thin they are, especially when backlight can be seen through the tan sidewall.
They are child’s play to fit, however, and slipped with ease on to my rims in a refreshingly simple and accommodating way.
Also inflating to exactly their stated width, the Hutchinsons produce a slightly lower profile, with the sidewalls easily visible from the saddle, which is a little surprising at first.
The surface tread is all slick, with long arrow-shaped cuts angled inwards, about every 50mm around the shoulders.
The low mass makes them extremely quick to accelerate, with superb road feel and amazing subtlety when pushing in to corners.
