I think it's just a regular 2 Bolt, 27.2mm seatpost clamp. Did you ask Darren if he had a Summit specific seatpost clamp, or if he had a 27.2mm 2 bolt clamp? Im pretty sure just a standard 27.2 mm would work.
I called Darren as well, and I believe it is a 30.7mm. I Darren didn't have them, nor UDC or the LBS. I don't know how to get one. I was lucky that the guy I bought my Summit from sent me the original.
I found one. I got it yesterday actually. I measured the seat-tube with some calipers, and I think it was 31.9 mm. But my bike shop guy said he ordered another. It fits anyway. It was made by Pizzazz. I'll ask the exact size tomorrow.
