Sticking with Walter @ Bike Friday for a moment – he has an interesting post on his blog about how to setup a Bike Friday as a fixed gear. I’ve been intrigued by fixed gear bikes for a while and have even toyed with the idea of adding one to my stable. I test rode a Surly Steamroller and came away with lots of questions, but no real certainty as far as deciding to get one. I may see if the fine folks at Bow Cycle will let me borrow a Steamroller for a few weeks so I can try it out and write up a review. Who knows I may not want to give it back!
A fixed gear folding travel bike makes a lot of sense as you don’t need a rear brake/derailleur or front derailleur which does away with three long cables you’d otherwise have to manage when you fold the bike. There isn’t much to damage in transit so you can be fairly certain when you get to your destination your bike will be ready to rol.
