I'm looking for a hope qr seat post clamp for my 1999 Explosif.

The internal is 27mm.

Any idea what external seat post diam is?

I can get the Verniers out tonight, but if anyone knows, all the better.
 
EXPLOSIF
Our top of the line steel hardtail is a classic Kona model. Although steel frames are generally heavier than Aluminum, Reynolds 853 is lightweight and has the resiliency that many experienced riders prefer. Steel is an efficient "spring" and provides a comfortable & fluid high-performance ride.
Constructed of Reynolds 853 tubing.
Tubing dimensions: Top - 31.7 x .8/.5/.8t, Down - 34.9 x .9/.6/.9t, Seat - 28.6 x 1.2/.6/.9t, Seat stays - 18-16.5 x .7t, Chain stays - 22.2-16.5 x .9/.6t.
Custom drawn, oversized stays with Kona "New Drop" investment cast dropouts dramatically improve braking and accelerating performance.
Made for 27.0mm seat post, 28.6mm front derailleur, 68/110 bottom bracket, & 1-1/8" headset.
Available as frame only, 4.2 lbs (18").

i.e., you need a 30.

'Seat - 28.6 x 1.2/.6/.9t' means it's basically a 28.6 external dimension tube of 0.6 gauge, butted internally to 0.9 at the base and externally to 1.2 at the top. So the external dimension at the top is 29.8.
