That's right: you can mount tires on these rims as you would normally, with tubes. Or you can mount them sans tubes; the tires will seal on the rim. They'll seal better if you buy the not-included Euro sealant - at $13/wheel.
Generously, tires for tubeless mounting are included. No cassette is included, but you can buy wheel models suited for Campy or Shimano cogsets.
The front wheel features 18 spokes, the rear 20. The wheels are light and run on good sealed bearings. I'm sure they ride wonderfully, and your bike feels lightfooted as Winged Mercury.
Why would I care about these wheels? Well, they're twenty-five hundred dollars the pair.
I know that the Hutchinsons are not the most expensive wheels for sale in This Great Land.
I know that some wheels cost (per pair) twice as much as these Hutchinsons, as much, say, as a restaurant quality Wolf Range for your kitchen - a luxury item I can sorta understand. You don't throw the Wolf Range in the trunk of your car and you'll have it forever, even if you crash.
The people who are buying these Hutchinson wheels and the ones that cost twice as much already own Wolf Ranges, am I right? So there's no conflict. Jeez, guys, This is a Great Land.
