We proudly present Fulcrum's newest member of its Racing family, with an extension of its already wide selection of disc brake specific wheelsets. The Fulcrum Racing 3 DB represents the newest and perhaps most versatile wheelset to date. Its aluminium construction and performance design make it a surprisingly efficient and reliable wheelset, sure to please no matter where it is put to the test. While the Fulcrum Racing 3 DB can certainly be used for pure road racing, it excels in road endurance and gravel, making it an extremely versatile all-around wheel. Performance does not always require rigidity and for endurance or gravel scenarios a more comfortable and compliant wheelset translates to better riding. The Racing 3 DB’s construction allows it to be 25% more comfortable than the pure road racing specific Racing Zero for example. Lower tyre pressures, bigger tyre dimensions, better grip, wider rim structure, increased comfort and better braking make for a long list of advantages that only a performance wheelset can bestow upon ride quality. The criteria for performance around this very versatile wheelset might be different but there is no denying that it is performance oriented but with a valuable dose of extreme versatility included. There are few better choices for the cyclist looking for the right tool for the job. The 1660 gram Racing 3 DB oddly enough is the right tool for many different jobs.

The wheels are compatible with tubed tyres too. The rim is 24mm wide and 22mm deep. It weighs 440g. The rear rim has offset drilling for increased NDS spoke tension (this is a good for spoke life). The internal width of this rim is 19mm and it has a 2mm thick spoke nipple bed. All tyres will sit wider on this rim than they would on a narrower one. This improves rider comfort due to the increased air volume and due to the different tyre shape handling in the bends particularly over broken road surfaces is improved. 24F/28R Black straight pull CX rays front and Sapim CX sprint spokes rear - 100/130mm OLD. Sapim CX Sprint spokes are used for the rear for increased radial, lateral and torsional stiffness over using Sapim CX rays which also means longer spoke life.
