Travel 120mm Carbon Hardtail Frame

I'd go a bit more conservative:
- fork 120 or 110 mm, in a 67,5 - 68 degrees HTA, respectively;
- fast as f...k, shortest chainstay possible; as light as possible;
- nothing wider than 2.4 tires - max 2.5 (but that's just to clear some mud, 2.35 are perfect for me);
- double RD hanger: either UDH or traditional;
- should take at least oval 36T, even oval 38T chainrings;
- internal routing;
- speed machine, for sprinting and cross-country eliminator (XCE) racing
- capable on downcountry, but nothing to compete full-sus bikes.
- a platform for tweaking and experimenting (so, as versatile as possible to newer or older tech).

Another underserved market that could be interesting is the light trail hardtail market (120-130mm travel). A lot of the big bike brands have gone all in on full suspension downcountry bikes, so there are very few of these carbon bikes that actually have a “modern” geometry (e.g. hta~66.5, sta >75).

Off the top of my head, I can only think of two carbon light trail hardtails:

Yeti Arc
Ibis DV9

The caveat to this is that these bikes need to have wider tires (29x2.6) which compromises the max size of the chainring.

The Cannondale Scalpel HT too.
