Rare Derailleur Type

Howdy Folks,

I just finished building myself a new bike from this generic aluminum cross frame, and it runs sweetly, except that I can't find a propper front derailleur for my needs. I started with a Deore LX on there, but took it off and now justkick the chain to shift.

The problem: I got a 52-40-28 biopace chainring, but I need a TOP PULL derailleur with a 31.8 clamp.

Does anybody know is such a thing exists? All of the shimano stuff that fits a 52 is bottom pull. Cyclocrossers usually don't have 52's, so they just use MTB stuff.

Did SunTour ever make such a thing?

OR: has anybody ever seen a cable guide which can switch a top pull to a bottom pull? With a 31.8 clamp?

I'll use this info to know what to look for at LBS's and on ebay


Thanks--

A clever person can rig their own cable reverser with a pulley and some hubba bubba.
