Hutchinson Fusion 5 Galactik Tubeless Tire

The Fusion 5 series of tires truly represents new generation of tubeless road tires. Hutchinson has developed a compound blend that allows them to specialize depending on the ratios and grains used. The Galactik has represented the ultimate tubeless race tire in the past, and the French tire wizards carry that moniker forward into the Fusion 5 series. At just 250 grams (!) in a 700x25, the Fusion 5 Galactik is feathery light, with incredibly low rolling resistance at any pressure. It maintains the same strong level of puncture protection as the Fusion 5 Performance, and still has void tread pattern for grip, but sacrifices some longevity and wet surface grip in the quest for light weight.

Hutchinson pioneered the road tubeless tire system in partnership with Shimano and has the most development and production experience. Their flat carbon bead system is designed work perfectly with Road Tubeless rims, and won't stretch with use, preventing accidental roll off, even in case of a serious flat tire situation. As with all tubeless tires, there is no internal friction from tube/tire interaction, so overall efficiency, even at lower pressures, is assured. The 127tpi casing is the perfect structure for the Fusion 5 tires. The casing offers a consistently round shape, with more than enough suppleness under pressure, yet enough strength to feel substantial. The rubber is called HDF-5 and Hutchinson considers this compound to be the pinnacle of development for all-around tires, offering their best combination in the 5 performance highlights of a tire: Grip, Efficiency, Durability, Puncture resistance and Comfort. The butyl sealing liner is joined by a flexible Kevlar puncture protection belt for additional flat protection under the center tread. The tread design is advanced with tread voids that sipe away water and provide grip when cornering that exceeds previous versions.

With bead to bead puncture protection and a butyl sealing liner, the Fusion 5 Performance Tubeless reduces the possibility of puncture, and eliminates pinch flats- resulting in a safer tire all around. The use of Hutchinson's Protect Air Max Sealant can quickly fill small punctures and help provide a premier seal at the bead. This Fusion 5 Galactik weights the balance towards speed and highest overall efficiency, though you can expect lower overall mileage. That is the basic assumption made with any true lightweight racing tire. When you factor in the average road tube at just over 100 grams, this is lightweight set-up, even if you use 50g of sealant.

Road Tubeless tires should be used with Road Tubeless rims for optimal safety and performance. As with all products, Road Tubeless tires have greatly improved in the technology's life span. The Fusion 5 series from Hutchinson stands apart, with a choice of compounds that specialize. The Fusion 5 Galactik sits among the lightest possible racing tires when all options are factored in, and with the advances in compound development and overall tubeless technology, you can race on one of the smoothest, sure footed, lightweight tires available today, regardless of type. It is perfect for summer racing on road or triathlon courses, and don't worry, even in a little rain, the grip is competitive with most other tires.
