With wheels for road, triathlon, and mountain biking, you may have noticed that Fulcrum’s ‘gravel’ category on their website is suspiciously empty. That’s because it will soon include their newest wheelset – the Zero DB gravel. Using many of the same technologies that make Fulcrum/Campagnolo wheels top notch, the dirt road crowd will soon have true tubeless option in the form of the Zero DB.

Thanks to their Mo-Mag system, the Zero DB rims offer true tubeless compatibility meaning the rim has zero holes except for the valve hole. The design also allows the wheels to be built with traditional threaded spokes and nipples, though they are specific to Fulcrum. How is this possible? The nipples (which are magnetic) are inserted through the valve hole, then guided to each spoke hole by a magnet on the outside of the rim. That allows the nipples to be replaced if damaged, and essentially for the wheels to be built in a traditional way. These rims in particular have a 19mm internal width.

The straight pull spokes mate up to AFS centerlock or six bolt hubs that are compatible with QR 135 or 12 x 142mm thru axles in the rear and QR, 12mm, or 15mm thru axles in the front. Available with USB ceramic bearings, the wheels have a claimed weight of 1590g and will be available later this month.

Wish my recent Campy Zonda DB wheelset was updated prior to my purchase (its their C17 non tubeless rim). Regardless I like them so its not a big deal. I’m personally a fan of the Campy Mega G3 spoke pattern and would choose this over the Fulcrum 2:1. Campy has Shimano freehubs so its not like one can only run them on Campy trains.

Campy is Campy only. Shimano/SRAM is same free-hub.

No. Campy makes Shimano/SRAM freehub bodies for their wheels hubs. Very few people use them as most people think is faux pas to mixed campy wheels with shimano/sram, but they have them nonetheless. That “faux pas” is the main reason Campy launch fulcrum.

granted, campy wheels ship with Campy freehubs, so the change over adds $60-$100 if you are running Shimano/SRAM
