Bontrager Betasso RSL GX

While you can ride it on pavement, this tire is specifically optimized for loose, rugged gravel. The aggressive knobby tread pattern will feel draggy and noisy on smooth asphalt compared to a dedicated road or light-gravel tire.

Yes, although they are designed as tubeless-ready, you can certainly install them with standard inner tubes if you prefer. However, running them tubeless allows you to take advantage of lower tire pressures for better traction and comfort on rough terrain.

The Betasso RSL GX features a robust construction with both bead-to-bead and sub-tread reinforcement layers. This dual-layer approach is designed to handle sharp rocks and trail debris, significantly reducing the risk of flats during demanding rides.

The dual-compound design balances two needs: a firmer center rubber helps you maintain speed on straightaways, while the softer, medium-density shoulder knobs provide extra grip when you lean the bike into corners. It gives you a predictable feel without sacrificing efficiency.

These tires have a 29-inch diameter, which matches standard 29er mountain bike wheels. However, at 55mm wide, you should verify that your frame and fork have sufficient clearance to accommodate this volume before purchasing.
