SL 1 Climbing WheelSystem


Balanced attack. The all new SL 1 climbing 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. Clincher and tubeless compatible, SL 1's lightweight alloy construction produces a wheelsystem that weighs in at just 1585g while offering an unbeatable ride.
