...on the non-Xtra bike, that is.
Wonderful! How do you mount the flag pole?The rest of you feel free to post links to your own pirates and bike photos.
I put an endcap with a long bolt on the end of the pole and attached it to the kickstand plate. Then, I used an old metal reflector bracket and ran a bolt through the pole to it for extra stability right at the seatpost. Piece of cake! Everyone should fly a pirate flag -- it garners motorist attention like nothing else...
