I have a Peugeot fixed gear and people I run into that have Peugeot's say the bottom brackets give out. What do I need to do? Can I just switch out the bb for a new one and keep the cranks? I've never messed with 3 piece cranksets before so I'm not familiar with switching it out. I wouldn't mind haven't shorter crank arms and the bb definitely sounds like its kinda giving out. I've read sheldon's site and part on the French makes but it's still a little unclear to me.
If anybody who is familiar with my bike and knows any specific links to parts I could get for a reasonable price that'd be awesome. Thanks.
You'll need a French threaded BB (Velo-Orange sells one; I would link, but I'm lazy), and new cranks (you'll replace them sooner or later anyways, and if you look on Craigslist for long enough you should find something decent for <$50)
If you don't want to buy a new BB you can check out bike co-ops in your town that will help you rebuild your current one
Velo-Orange sells french cartridge bottom brackets, which I'd go for. Or, like someone said, take it down to a bike co-op and rebuild it from used parts. I'm assuming you have cottered cranks, so yeah, upgrading to a more modern, square taper, would be a good idea. Make sure you screw in that fixed cup crazy hard though, the french threading tends to make it unthread itself (at least in my opinion.)
