Speed is synonymous with competition, and represents the ultimate in performance needed in a top of the range wheelset. The Speed 40 DB was created for World Tour professionals. The Speed 40 DB is a set of wheels for use with disc brakes that will simply leave you speechless, featuring a cutting-edge rim with a new shape, designed to innovative technical concepts.  At 26.5mm, the wheel is wider, with an aerodynamic shape which includes a pronounced 8mm profile and a "twill" weave carbon fibre texture, optimising the elastic responsiveness of the rim.     The Speed 40 DB boasts a 2-Way Fit construction and as such is tubeless by conception with a 19mm wide channel, and a USB ceramic cone & cup bearing system.
