Does anybody happen to know the weight of the rotary clamp hardware (ears + bolt + rotary clamp) for Bontrager seatposts?

Also, Bontrager lists two optional ears for carbon oval rails: 7x9mm and 7x10mm. Is the 7x9mm a better choice for Selle Italia SLR carbon rails (7x9.6mm)?

Thank you.

If I remember correctly from my build, it's 12g.

For your saddle, I'd go 7x10.

^^^Thanks FIJIGabe. Is that weight for the ears only? Because I think all the loose parts weigh a bit more (ears, bolt, spring, rotary clamps).

Sorry, I was really off. The weight of the ears is 29g for the 7x10 versus 21g for the standard 7x7 version.

Thanks! I wish someone would make a lightweight version of the rotary clamp hardware.
