Mavic rims and hubs, lots of flexibility for all possible wheel set ups. My set up came with 30mm tires and I set up my Litespeed Gravel grinder with these using 15 mm thru in front and 12 mm through axle in the rear. Now getting the various end cap set ups to work is not easy and there are no instructions. It is really just brute force to get the end caps off and to replace with the configuration you need. The tires are soft and I had two flats pretty quickly. However, the mavic tires were tubeless and I have converted to tubeless and no flats since. With the 30 mm tires the wheels since a bit heavy, but hey I am also riding over dirt roads. I am running 70psi pressure and I think that is key for these wheels to run lower pressure, otherwise you will get some flats as the tires are pretty spread out with the 19 mm internal width rims. Overall I like these wheels and they look great too.
Light wheels make a big difference when climbing and these are some of the lightest. But what about your reward for all that climbing? The high speed descent... These wheels are stable and quiet at high speed and they have a huge braking surface. I have used these wheels for RAMROD, High Pass Challenge, Copper Triangle, Triple Bypass and several trips up to Timberline Lodge (your basic epic mountain rides) and these wheels quickly transfer power on the way up and on the way down. And when I have hit the inevitable mountain road pot holes, these wheels remain true. In fact I've gotten several years of use on these wheels without ever having them trued. Great wheels.
I bought these wheels to compliment a rain bikecommuter (Soma Double Cross Disc). These wheels are bombproof, reasonably stiff, and for the price you can't shake a stick at them.
I really like how solid these wheels feel on rough pavement. They're not light but they ride like a lively brick ****house. Seriously, for the money, you can't beat these wheels.
I also appreciate that they're completely rebuildable.
I recently downgraded from Fulcrum Zero due to the harsh ride but still wanted tubeless compatibility. So I recently picked up the 2-way version of this wheelset at a discounted price and all I can say is a big difference in ride feel! The bumps get soaked up while the stainless steel spokes makes the ride more compliant compared to the Zero. Yes, the Zero is the lighter wheelset but the difference is only 150 grams (and the USB hub, which I couldn't tell the difference). It's from Fulcrum so you know the reliability is top-notch.
For the price point and mid-range weight, Fulcrum Racing 3 would be a good alternative to Zero.
