The classic GT-40 cage is now even more versatile in a side-load format. An ideal bottle cage solution for tight frame triangles of smaller-size, full-suspension, sloping top-tube, or aero bikes, the GT-40/S side-loader can still be used on standard-sized frames by riders who simply prefer a different bottle-loading option. Crafted of lightweight and durable heat-treated aluminum for smooth bottle insertion and secure grip.
