Clamp size for front Derailleur?

[thomas]

I have a 1998 proflex 5000 (sweet bike) I am replacing the front derailluer and I am not sure the clamp size.  Does anyone off hand know this?  Thanks.

My 5500c is a 31.8mm.  But I don't for sure what the 5000 is.

I have an 18" 5000 1998 frame with a Shimano Deore Mega9 top swing link dpull 34.9mm mech with a set of downsizing adapter clamp plates as it is oversized, so guess the seat tube diameter is the next one down, 31.8".
cheers,

Ps I neglected to let the last guy who requested this  (Eric Holland), know that I used the supplied downsizing clamp adapters, (misread the initial diameter), so Eric, if ya reading this, soz mate.

If you order a new (2004 or later) Shimano Deore or 2004 XT then the front mechs come with spacer shims to fit all three common sizes.

I've got 98 5000, too.
Size is 31,8 mm Downpull Topswing.
Downswing don't fit!!
