The Eulen Group jersey, signed by several cyclists, highlights the company’s commitment to Basque Under-23 cycling in the 2010s. Eulen sponsored a team of promising young riders, acting as a feeder team for the professional ranks; its ranks included several national champions from the junior categories. The numerous signatures on the jersey may include riders who went on to turn professional, which enhances its value. Displaying it recognises Eulen’s work in promoting grassroots cycling and the collective success of that generation, whose members are now scattered across elite teams.
