Japanese brand Magic Number have worked with fixed gear crew Trackheads from Kyoto previously and this is one of the t-shirt designs that was made for Trackheads. However this is a special colorway made only for online store H.L.N.A. and is only available at H.L.N.A. The innovative design is a graphic based on two chain rings that seem to hang off the neck. Each brand's logo is carefully placed on the chain ring that flows with the overall design. This version is screen printed in red over white body and it is also accompanied by small collaboration graphic on the rear bottom of the shirt as well.
