The Quoc Gran Tourer XC - Black, has exceeded my expectations. The refined look blended with amazing comfort has elevated my biking experience. Part of the comfort comes from the blend of performance-engineered materials which are durable, breathable and adjustable. The dials work, easy on, easy off. The other comfy part and the most impressive feature is the included arch supports of three different heights. I am only now, at age 57, feeling fully connected to my bike. (I'm using the highest arch) Follow the sizing video and chart online then place your order.
