Hi everyone,
I'm looking for a titanium frame for a gravel or all-road bike and was wondering if anyone knows of a model that ticks the following boxes:

Clearance for 40mm tires
UDH (Universal Derailleur Hanger)
Fully integrated cables (ideally through the headset)
Invisible welds around the headtube
Aero seatpost would be a plus, but not a must
Does something like this exist, or am I asking for too much in one frame?
Any suggestions or leads would be greatly appreciated!

Thanks in advance!
