Hmmm... perhaps I have the 7x9 clamp then. I just assumed Trek/Bontrager only made two... one for 7mm round rails and the other for the rectangularly shaped rails. I was unaware they make 3, one for the round rails, one for the 7x9 rails and another for 7x10 rails. I will have to check on that. Thanks.

And @Slack... your world class illustration works just fine thank you.

Just to update... Bontrager/Trek do make a 7x9 clamp, as well as the 7x10 clamp and standard 7mm round clamp. I haven't had an issue with either the Romin Pro slipping or getting damaged using the 7x10 clamp but I've gone ahead and ordered two of the 7x9 clamps. They only come in silver however. Wonder if the black Specialized 7x9 ears will fit in the Bontrager style seatpost? They look similar in design.

I have the opposite problem and so have a used set of 7x9 side clamps that I'd like to swap for your 7x7 clamps if you're still in search of a solution.

The clamps I speak of are part of this: https://www.specialized.com/bg/en/compo ... 9mm/105105

They're in transit. Hope you get them soon...

I have a set of 7x9 (carbon rail) side clamps for the CG-R. I'd love to trade for a set of 7x7 (alloy rail) clamps. What I need is pictured. In case anyone else has this issue.
