Thanks Bazzarch, that makes sense to me - it's been nagging away at me ever since I wrote the original story about the mini-drome and couldn't find anything out about kloides anywhere.
'kloides' is most likely the 'street math' term for 'cycloids'.
Used to hang out with the wrong cantor set in my youth.
Ok this is really geeky but it bugged me that using a cycloid didn't make sense in this context. The company who made this is german, and I think the bad translation of 'Kloides' is not from cycloids (Zykloides in german) but clothoids (Klotoides). Clothoids (aka Euler spirals, or Cornu spirals) are the solution you get if you try to make a continous transition from a straight path to a circular path - ie acceleration towards the centre of the circle increases linearly from 0 to some maximum g. More on this here:
http://en.wikipedia.org/wiki/Track_transition_curve
Bizarrely, while clothoids have been used since the mid 19th century to design smooth curves on train tracks, they've only been deliberately used for velodromes since Atlanta '96 - a computer designed track made by the same people that designed Red Bull's minidrome - who now work at worldrecordtracks.org . (See, this all made sense in the end)
I'd like to see a madison event on that.
