A 1800 SPLINE® Blistering speeds within everyone’s reach. Our A 1800 SPLINE 30 has been entirely designed to enable you to reach impressive speeds whilst having fun. Based on our first aerodynamically optimised aluminium rim, it marks the democratisation of our Aero range. In addition to the rim, concealed nuts and aero spokes further enhance the aerodynamic advantage. So, what are you waiting for? Fit them to your bike and set off in pursuit of KOMs with speed and the wind as your allies.
