The Riddler 45 is the best tire for gravel, offering comfort in a wide range of conditions, with minimal loss of speed and air volume for long rides, including gravel.
The Riddler itself was originally designed as a mountain bike tire, but with this renewal it has been transformed into a tire for gravel, with its large side knobs giving a feeling of security when cornering and its low, fine knob in the center reducing friction on the pavement. The large side knobs provide security when cornering, while the low, fine knob in the center reduces friction on pavement, making it suitable for long distance riding and touring, including gravel.
*Recommended rim width is 28mm.
*TCS specification allows for tubeless use with the use of sealant.
