Giant’s all new SLR 1 Disc Centre-Lock Wheelsystem features ultralight full composite construction, weighing in at just 1650g (per full wheelsystem). With a modern 23mm wide and 30mm deep rim profile, SLR 1 feature Giant alloy centrelock disc hubs and are clincher and tubeless compatible. SLR 1 are built using Giant’s Dynamic Balanced Lacing system – so spoke tensions balance out as riding forces are applied, resulting in a stiffer, more efficient wheel.
