If you want to avoid pinch flats or want to run lower tire pressure, than tubeless is definitely worth it for an xc rider. You'll get a slightly more plush ride and improved traction. You can also add some sealant for added puncture protection. There are many pros and cons, so you'll have to decide whether it's worth it for your riding style and terrain. If you're a light weight, smooth rider that rarely flats, the benefits are not as great compared to a heavier rider that likes to fly through rock gardens at full speed. If you already have tubeless compatible rims, it would be easy to give it a try and decide for yourself.northparkrider said:
