Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

thinking of converting

hey guys, i was thinking of converting my OCR3 to a fixed gear. now i dont know anything about it so i came here to help. and i wanted to do this little project on my own. so what i would like to know is, what parts do i need? the only thing i can think of is to remove all the shifters and other cassettes. whats a good combo to have it on? i have a triple on my OCR3 so would the biggest one up front and smallest one in the back work? i guess i would need new tires in the back and different brake levers. other then that i have no idea. and i dont even know whats a good brand and whats a good rear tire or anything. can you guys help a newbie out?

You would need a rear wheel with an Eno Eccentric hub (to get some ajustabilty from a short dropout,) a cog, and a lockring. You might be able to still use your current brakes after the derailers and their cables are removed. Most likely spacers will be needed to get a good chainline.

if you're thinking of converting, you might be better off finding an old steel bike at a thrift store and buying a fixed rear wheel on ebay.
a great place to start learning about fixed-gear conversions is sheldon brown's site; http://sheldonbrown.com/fixed-conversion.html

there're also a bunch of helpful folks on these boards; most of your questions have probably already been answered by one of 'em at one time or another, so go nuts searching old threads.

if you can't find an answer start a new thread.

good luck and welcome!

This makes me wonder is a sticky FAQ may be helpful for this forum as this question seem to come up reasonably often.

before you do anything, ride around a while without switching gears, to answer that question. you can use sheldon brown's gear calculator if you want to keep that ratio but use larger gears, and/or if you're going to use bigger/smaller crank arms on your conversion

Go with the White Industries Eno hub as mentioned above. This allows you to adjust chain tension at the hub due to its design. It will allow you much more variation in what ratios that you can run with the vertical drops. A few people on here (specifically Fungazi Dave) use this hub on a road frame and love it. As a bonus, the hubs come in 3 different spacings (126, 130, 135) so that you will have a good chainline.

Yeah, I rebuilt my rear wheel with the White Industries hub when I converted roadie to fixie. It's a great hub for this application.
