Unique 23++ 700 X 45C Tires
Unique 23++ 700 X 45C Tires. The wtb riddler 700x45c is the gravel incarnation of the mtb tyre of the same name. The wtb riddler is decently large volume 700 x 45c tyre, designed to tackle a wide range of conditions and surfaces you'll encounter gravel cycling. Roll up to the local cross course or escape to the gravel backroads, the riddler 45c is just as ready for either. It has become very popular across the pond, so i felt it was time to.
