Surly Jethro Tule toolSurly Jethro Tule tool is built from stainless-steel, then polished to a high luster. An offset box wrench on one end (for the single speed crowd) coupled with a "leverage-enhanced" bottle opener on the other end make it handy and convienient.
The double-sided 15mm box wrench works with most bolt-off hubs on the market.
It fits easily into recessed dropouts, including those found on Surly 1x1, Karate Monkey, and Steamroller frames.708752056602
