| Weight | How much does this bike weigh? It’s a common question, and rightly so. But the truth is, there are no industry standards for claiming bike weights—and this leads to a lot of misinformation. Variances exist based on size, frame material, finish and hardware. And as bikes get lighter, these differences become more critical. At Giant, we believe the only way to truly know the weight of any particular bike is to find out for yourself at your local retailer. |
