I ended up getting the Trifox. It does have 3 ports in the headtube, allowing for the internal dropper cable.
Overall, the quality is v good. I weighted the bare large frame at 912 grms.
Supplied seatpost is rubbish, a good bit less than 30.9, so loose in the frame and slipped during 1st ride. Dropper in there now.
The rear brake threads were tight, and I needed to add washers to the caliper bolt as the hole in the frame was not that deep.
The rear derailleur exit port was poor. I needed to dremel out the insert so I could feed in the outer casing.
I got the 740mm trifox flat bars, seem good quality and I weighed them at 152 grms.
Threaded BB is nice, 73mm so no spacers required.
2.35 maxxis tyres fit fine with good clearance.
The rest of the build was XT/SLX mix. Wheels are ztto microspline hubs with carbonbearm rims. 1450 grms. Snail china xtr chainring copy is nice.
