Matt Cardinal’s Daily Derailleur Instagram illustrations are amazing and after many requests, he’s begun putting them on t-shirts. So far, a Shimano shirt has popped up, with what appears to be a Paul derailleur shirt in queue. Head over to Matt’s Instagram to follow the sales and TeeSpring to order one of the Shimano shirts.

Edit: Matt just updated the TeeSpring site to include a web store with three designs, including the Paul derailleur.
