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)

Bottom Bracket Spacers

Do any of you use these? They come in all kinds of widths and work miracles
in achieving a perfect chainline for those of us who don't have Phil BBs
with the adjustable spindle.
Just installed one yesterday. My chainline is now only 0.04mm off, which I consider
perfect, except when viewed on paper.

WTF? Your chainline is .04mm off? Do you know how little that is? That is almost the thickness of an aluminum beer (or pop) can. .04mm of vairation can be from your chain. Don't worry about it. It won't make a difference. also making a .04mm bb spacer would be hard.

No, the chainline was off before but now the BB's been spaced over so it's only off by 0.04mm. That's the NEW deviation.

Do the spacers make pedaling awkward? If one leg is a few millimeters out because of the spacer, that would be weird.

Hmm... what and where.. Why look, the Google knows! http://www.google.com/search?q=BB+spacers

little5guy, do you really place your foot on your pedals to a precision of a few mm's?
