I thought oem full builds from any manufacturer were always tubes out of the box.Did not buy A2s (yet).
Put the 180 mm rotors on. While doing so I noticed that the valve stem on the rear wheel was crooked, which only happens with tubes. Somebody here mentioned that the OEM build might have tubes and you were right! So weird.
Ganked out the tubes, slapped in some tubeless valve stems & sealant and now I’m tubeless. Post faffing & swapping weight was 29.5 lbs.
Hit the big steep line twice on the group ride yesterday. Felt much better than the first go around.
