Jethro Tule combines a bottle opener and an offset box wrench for your opening needs and tightening pleasure. The double sided 15mm box wrench works with most nutted hubs out there, and fits nicely inside recessed dropouts like those found on many of our own frames, such as the Steamroller and Karate Monkey. The Tule’s spoon shaped handle is designed to fit comfortably in your palm, and its heft feels good in your pocket.
