Road Tubeless: A look at Shimano Dura-Ace / Hutchinson combo
Outside magazine has an online feature about the new Shimano Dura-Ace wheelset that can run Hutchinson’s new tubeless tire, the Fusion 2 Road Tubeless.
It sounds really good:
As expected, things were noticeably smoother. Cornering was also more stable than I’m used to, since the lower pressure leaves more tire in contact with the road. I would love to have had a power meter to see if the rolling resistance was really comparable to my normal setup. But in purely subjective terms, I didn’t feel like I was working any harder. The wheels wind up quickly, hold their speed, and are race-day stiff, while the tires offer noticeable handling improvements.
At a claimed weight of 1,560 grams per pair, the 7801’s are about 100 grams heavier than comparable standard wheels. But you more than make up for that by leaving the pump and spare tubes at home. The tires weigh about the same as a standard tire and tube combined, so weight there isn’t a concern. The Fast Air cans are a necessity, though. Without them, the tires lose air in a matter of hours. But with them, you won’t even have to think about your tires.
