Balanced attack. The all new P-SLR 1 Aero wheelsystem features Giant's breakthrough Dynamic Balanced Lacing technology which ensures rear wheel spoke tensions are balanced under load - not while static. The result of years of development with Giant engineers, product designers and pro athletes, DBL produces a wheel that offers improved acceleration and climbing response along with durability, while optimised anchor points increase lateral stiffness for exceptional cornering performance. Combined with exceptional aerodynamics, clincher and tubeless compatible, SLR 1 Aero's ultra lightweight full composite construction produces an aero wheelsystem weighing just 1700g while offering an unbeatable ride. UCI and ITU tested and approved.
