the cars r coffins zine is all about singlespeeds with a little bit of fixies, and a little bit of punk rock... but mostly singlespeeds. their logo is on the bianchi s.i.s.s. they have a website http://www.carsrcoffins.com/ and you can order the zines from them.
some friends of mine and i were considering starting a zine or something at one point. the idea is still floating around, we just need content. there's only so much the few of us can write about without getting repetitive and boring.
to keep us occupied in the meantime we've started a website dedicated to our singlespeed/fixed gear riding, onegear.com
right now it's mostly a journal type of site, but we plan on adding product reviews and all that good stuff eventually.
