Trying to catch up on all my messages. As good practice with budget frames, I always use expander plugs from the brand called "Neco" which can be found on Amazon for like $13-$20. Length large, aluminium or carbon top cap. Not the lightest plug ever but no slippage. Especially if you plan to run spacers above the stem

Hello everyone, 1st post here but not my first bike, I guess this is my #20ish installed "no brand" bike in 15 years.
All went fine, especially as I decided to go AXS so it's super fast. What required more time is the routing through the (separated) handlebar. With a traditional handlebar, which requires an open window in the headset top cup, this would be easier but less pleasant from an aesthetic POV. I'd do this way next time (or the first time I'll need to change headset bearings).
One problem so far, for me, it's the "carbon" saddle clamp: as others noted it's too small for a 9mm height rail. I just wrote Chris for an updated clamp. For now, I Installed the 7*7mm clamp with a heavy Fizik saddle.
About weight, well...it's not its strength being a little "porky" but it's not too bad either (8.2 Kg as in photo).
I'll try it in the next days, checking seatpost "slippage".
Going back, I'd go with a 177, but now here it is.
Boring matte black, but hey, (less) grams!
