Singlespeed & Fixed Gear - Chain length...
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
This might be a stupid question, how do you determine the proper length for you're chain? I know on my multi-gear bikes I just go big big and add 2 links.

I put the rear wheel in just enough so there is full axle washer contact. Then I put the chain on as tight as possible. It should still have slack, then I loosen the nuts and pull back for tension. I really push back, grabbing the wheel at the BB and levering with my thumb against the BB. This way I can keep the chain snug and wheel straight while tightening the nuts.
i've always put the axle in the middle of the dropout/track end, and then size the chain as appropriate. it makes sense to me to do it that way so i've got room to move about if i ever feel the need to change my gearing.

........and of course, if your dropouts/forkends/trackends are a bit on the short side or not quite horizontal and you're unable to place your rear axle at a desired location, "half-links" of chain are also available. When I first heard of half-links, I had a hard time visualizing what they look like because I knew what a full link looked like......I thought how you can link a chain with just half of a full link........hmmmm......but I figured it out. Haven't actually seen one yet, though.......except in my mind......and it really works. Spoke to a few people who use them on the Fixed-Gear Mailing List.
Anyway, I think Sheldon Brown sells them for about $5 per half-link. Thank you!!

i have a converted road bike with short semi-horizontal drops and i used a half link that i got from harris-cyclery for 5 bucks. theres 2 kinds of half links ive seen out there, and the style sheldon has is a higher quality than the kind you can get at dans competition, although dans is cheaper
