Designed to be compatible with bikes featuring flat-handlebar risers, the Delta Speed Aero Bar Riser Kit provides a practical and highly adaptable solution for mounting aero bars directly onto the cockpit. The risers can be installed using either bottom-up or top-down screws, thanks to the square nuts included in the kit. Once installed, Delta Speed aero bars can be mounted directly onto the risers, creating a clean and integrated setup. Each kit consists of two pieces, left and right, with a total weight of just 182 g per kit. The system is compatible with most two-tower triathlon and time-trial bikes, including models from Specialized, Trek, Pinarello, Quintana Roo, BMC, CADEX, Giant, Colnago, Wilier and other compatible platforms.
