Recap having read the whole thread, so far, there are recurring problems with rear thru axles threads that dont work, which make the bikes unusable.
Everybody seems to hate the Mavic thru axle system and nobody understands why that's being used.
The seatpost slips despite using massive torque & carbon paste. USUALLY, people report slipping seatposts because they tighten to 5-6nm, when this bolt is usually supposed to be tightened much more. Routinely up to 12nm. FWIW, my long teng frame says 12nm on the seatpost clamp. I would be very concerned to go above that number though, so people here saying they're tightening to 15, i hope it's on the direct instruction of VB, because if that area cracks, you can bin the frame. I cracked a carbon crank arm 2 weeks ago at 6-7nm. Carbon that explodes is not a pleasant experience, as it's an instant write off.
Earlier versions didn't have a hole at the bottom of the frame for water to drain out, but this seems fixed now, and easy fix anyway. One or 2 instances of bars missing an exit hole for the housing - easy fix.
Bottom line: feels very beta still. Loose thru axles, poor threads on thru axles, slipping seatposts basically means you can't ride the bike. For seatposts, presumably, you can shim some aluminium from a can to create friction. For the TA, i have no solution and i'd be very unhappy.
