Companies continue to focus on providing options specifically for gravel riding. Challenge recently had one at the Taipai Cycle Show.
Built with a file tread center and Limus like shoulder knobs, the 38mm clincher will sit alongside a 36mm tubular and open tubular. Competition take note, Challenge has licensed the name Gravel Grinder – to use it, you must pay Challenge $1 and one beer per year for use of the name.
