it would be possible to make it, would only need to make the right moulds, and that's the problem - it can cost quite a lot. And carbon isn't always the best material to work with in some cases, if you know what I mean. Otherwise sorry for my late answer, just saw your question today!
And finally some good news - yesterday I get the material that I need to continue with my frame project. As soon as I'll have some more free time I'll continue with my frame project. Unfortuantely I waited for almost one month that I get the material and probably it could be already finished, but anyway, I'm not in rush at all but it would be nice to make some more progress as soon as possible
Also the study year started and I'll have some more work...but don't worry, there is always enough time for some carbon projects
Back to the Sram Red clamps - I searched for some parts that I could use for those clamps (M6 screw) but just didn't found anything with M6 (that I need), only M5 screw...But I could make it with a carbon screw (!), would be insane light, but I'm not so sure how durable it would be...I'll just try to make it and we'll see, I'll keep you updated!
