so i guess i'm actually ripping off the bottle opener Felt gives away with one of their bikes, but i'm stoked on this 15mm wrench i drilled holes in to utilize the waterbottle cage bolts Surly so generously included with the Steamroller. gotta figure out how to notch the 14mm side to make it easier to pop bottlecaps off with. found a set of hex bolts with holes at one end to put on my keyring to get the cage bolts out. eureka!
