The 2024 20th year Cycle Jersey is here. New for 2024, the shirt is fully recyclable, same quality, sizing and features, just recyclable.

All riders are expected to wear a CARTEN100 cycle jersey on the ride, but of course you can wear your jersey from an earlier year.

Our CARTEN100 cycling jerseys are made from a technically advanced lightweight, soft and breathable fabric. The cycle jerseys have many features including elastic cuffs, silicone gripper hem and 3 rear pockets of which one is zipped as well as a full-length front zipper. These shirts are normal fit, not race fit, so choose your normal shirt chest size.
