Hello fellow riders,
I have a fixed gear that I built from parts (nice Reynolds 531 frame I could not leave
alone in the classifieds), with a carbon fork.
Something really weird happens from time to time, and last time it almost threw me over
my bars : the handle bars start to oscillate (left to right) at around 20mph, to a degree
that I have to very firmly hold them to avoid things going out of control and crash. I
have no idea what is causing this, but it is really scary.
Has anyone ever experienced this ? Is there a cure for it ? I'm guessing it has something
to do with the geometry of the bike, but really don't get it.
Lou

So just what causes shimmy ? (http://yacf.co.uk/forum/index.php?topic=22479.0)
Worth a read.

Thanks for the link, a lot of the comments make sense (not so much the coconut bra, though....).
