With Unbound Gravel just around the corner, Shimano has launched special edition versions of its best gravel shoes in the RX8 and RX6 as a tribute to the 'big boss' of gravel racing which attracts riders from all over the world every year to participate in the event held in Emporia, Kansas, USA.
Unbound is considered to be the best gravel event in the USA, if not the world, and is now in its 15th year, it's grown from a startline of just 34 riders back in 2006 to over 4,000 riders lining up in 2022, alongside World Tour roadies, gravel privateers, and professional mountain bikers for what is renowned as a 200-mile, hilly, tire-shredding, sun-baked gravel grinder around the famous Flint Hills of Kansas.
