A long time ago, ancestors enjoyed riding in search of a path they hadn't taken yet, called pass hunting. Nowadays, the genre of bikes that can travel on gravel roads has developed, and the range of ways to play with bikes besides just mountain and road biking has broadend. In particular, it is no exaggeration to say that tire selection is the most important factor in enjoying gravel riding, and various tires have been released. Gravel tires have different choices depending on what kind of road surface they are on and what kind of bike they are mounted on. Here are some recommended tires for 700c wheels and 650B wheels. We mainly choose WTB, which is good at playing on the soil, and SimWorks By Panaracer which is good for bikes that need many diffrent tire clearances. Also, as the number of bikes equipped with disc brakes has increased, the degree of freedom in changing the wheel size has increased, which is one of the most important points in choosing tires. If a certain amount of clearance is secured, it is possible to put on 650x47B tires with the same outer shape and volume for 700x28C, as in the Road Plus standard advocated by WTB, so for example, for the same bike. I think that it is a unique way of enjoying bicycles these days that you can play with one by changing to 700C and 650B wheels and tires depending on where and what kind of ride you want to go on.
