There is a neat story about a single speed Surly bike over on the MTBR forums. If you know your bike gear you’ll appreciate the story. The photos that go along with the story are also very good. Mmmmm, bike porn.
I don’t read MTBR regularly. The link to the Surly story was posted to the mailing list for the local MTB club I’m a member of. Maybe I should start reading MTBR more often.
