XDS X-LAB GT8 Frameset Every Road Ends. Keep Going. If you want a carbon gravel frame that can hold race pace on pavement and still feel composed once the road disappears, the GT8 is worth a close look. It clears a genuinely useful 55mm of tire, so sizing up for rough surfaces or loaded miles is never a problem. In-frame downtube storage keeps a tube, tools, or food out of your jersey pockets and off your back, and it doesn't throw off your balance the way a saddle bag can. A flex-tuned seat stay design adds compliance right where you feel washboard gravel and chatter the most. Mounting points are everywhere you'd want them - top tube, underside of the downtube, both fork legs, and the standard bottle positions on the downtube and seat tube - so building out a bikepacking setup is straightforward. Internal dropper post routing is ready for when the trail gets steep. This is a frameset that goes as far as you do.
