My beer opener doubles as a fixed gear bicycle. And no, its not one of those Surly chain tensioners w/ the bottle opener, nor is it the laser cut dropouts with the beer opener, it's not even a 'wisecracker' stem or seatpost-clamp beer opener, this one is 100% homemade.

The pics are crap-tastic (sorry) but the idea is simple-

Go to grocery store and buy a 2 pack of cheap bottle openers.

Hit the hardware store and pick up a couple bolts that mach the threads of the seat clamp bolts but are just a little bit longer.

While your shopping for hardware pick up a couple washers and nylon lock nuts too.

Grind the "pointy end" of the opener down so you don't hurt yourself.

Drill a couple holes in the opener that line up with the newly-extended seat clamp bolts.

Add the opener, some washers, and lock nuts on top.

Barely noticeable once installed but it cranks the awesome knob all the way to 11.

Cost- $1 for a 2-pack of openers, (2) $0.89 bolts, (2) $0.14 washers, (2) $0.22 lock nuts.
Total- $3.50










Cheers!
