Wider tires and Road Tubeless have both been gaining traction, and the new 25mm width in the Hutchinson Fusion3 brings both to the table.
Hutchinson already has the 28mm Secteur tire, but the popular Fusion3 tread has a bit more widespread appeal. We think that appeal is even wider now and carries a bit more weight. Puns intended. Like its 23mm sibling, the Fusion3 25mm uses a 127 tpi casing combined with dual compound rubber for a supple, grippy tire. While the size is interesting, it’s the rolling resistance that is the real story…
In order to test rolling resistance Hutchinson airs up each tire to a fixed psi and attaches it weighted to a rolling drum. After the tire is accelerated to 30 mph, the motor is stopped and the tire is allowed to coast to a stop while a counter measures the distance traveled. In the case of the 25mm Fusion3 versus the 23mm, the 25mm tire rolled an impressive 110 meters further. According to Hutchinson they really weren’t expecting results anywhere near that, but they were happy to have a tire that rolls so well.
Compared to the Fusion3 23mm, the 25mm looks quite a bit larger mounted on the same rim – more than the 2mm would indicate. Weighing in just under 300g, the tires are available now for $105.
