Any alternative Cervelo R3 seatpost clamps?

[Rudi]

I am building up a circa 2012 Cervelo R3 and have noticed that the seatpost clamp isn't round and is slightly "D" shaped.

I know there are plenty of light aftermarket clamps on e-bay but can't find anything about these slightly not round shaped ones. Search function here seems to want to ignore the "r3" part of any query.

Am I stuck with this? It's only about 18g but I have usually found this a cheap area to loose a few extra grams.

Thanks for posting, I was looking for a LW solution as well. Will keep an eye on the thread

Nope, proprietary clamp. You could lighten it up with a ti-bolt?

@newforker - Thanks for confirming this. I suspected as much. I'll get looking for a Ti bolt for this as I will probably be investing in some for the stem as well.
