I'm hoping to get some help sourcing high-end, sub 15 gram seatpost clamps for 27.2 mm seatpost/28.6 mm frame.

Something like a Tune Schraubwurger, Box Helix Fixed, KCNC SC-11 or maybe even a Controltech TiMania would be ideal but these are only available for larger diameter posts/frame combinations.

Pro and Thomson are options. The Thomson is 3x as heavy as the clamps above and just as expensive. The Pro clamp is a little better but I'd like to exhaust all options before I order.

Please let me know if you have a suggestion on brand, model or source.
