Challenge Grinder Tubeless 650b X 46 Gravel Tyre

Due to the flat-structured diamond profile in the middle, the Gravel Grinder from Challenge rolls very lightly. The higher shoulder studs for cross-trials and racing provide the necessary grip and stability in the corners. The profile of the light cross tire is specially made for sandy and gravel roads with rocks. This way you can make a lot of speed with your gravel bike without a great risk of punctures. The all-rounder can handle both hard and damp surfaces and helps you safely and lightly over the course.Features:- 120 TPI poly carcass- Aramid bead- Flat diamond profile with shoulder studs- PPS anti-puncture layer (Puncture Protection Strip)Specifications:- Model: Gravel Grinder- Use: Cross and Gravel- For inner rim size: 17 - 23 mm
