Well, after getting into cycling fairly recently, I have decided to attempt to modify my slightly junky Peugeot commuter to give it a little more class and speed. I have done a little research (this forum, Sheldon Brown, ordered some popular bike mechanic books), only to find the more I learn the less I know.
Therefore, I have decided to take my project to the internets! I plan to share my project, via this thread, with anyone who is nice enough to help, rude enough to deride, or bored enough to care about my progress and questions here. I plan to post pictures of what I've got now, and what I'm looking to get.
My first questions: what is up with different chains for different speeds? That is to say 8-speed chain, 9 speed chain etc? Shouldn't the only difference in chains have to do with the size, not the number, of gears?
I am looking at upgrading to all 8-speed parts, so I have found auctioned items that all say "8-speed." Is this necessary? For instance, I found an 8 speed cassette, 8 speed chain, 8 speed front and rear derallieurs. Is this necessary to ensure compatibility? Does that even guarantee that they will be compatible??
Thanks in advance for your help.
