PS: really feels like we've reached peak bike, one really needs a trained eye to tell bikes apart...

1. You plan to route 4 housings through the bars & stem using this https://jagwire.com/products/diy-cable-kits/2017road-elite-link-brake-kit? Having routed 4 VB bikes with keb-sl housing (full internal), i really dont think it's possible, so very curious to see how you manage that.

2. If i had extra spacers like that under my stem, i'd probably run an extra long plug expander to spread the forces over the widest possible area. Leverage is a thing, so if you hit a bad pothole, you're at a materially higher chance of cracking the steerer if you run tall chimneys like that. That's also going to add another sharp bend to the routing.

3. so the frame is 1060g and they advertise 950g. Did you ask if the 950 is a raw carbon weight? Primer & paint done by VB is going to add weight, idk if it adds 100g, sounds like a lot, but I'd say >50g. At which point a 50g variance is 5% of the advertised weight, i guess it's within spec? When you order rims, if it weights 460g, the seller typically says +/- 15g, and a rim is a lot less intricate than a frame.

Keep in mind that the so called official LTWOO store is not actually owned or run by LTWOO. At least according to Joe from China Cycling/Panda Podium. That’s why I just chose the best offer regardless of who the seller is and went with the 80s Designer Store.

let me know how it goes with the customs. I was thinking about buying that set but am afraid of customs here in BE

Nice build, thanks for posting!
Other than the paint, anything to report on? Holes that aren't round, tolerances that are off, brake mount surfaces that aren't flat, inside of the frame that looks crap, any of that at all?
Very helpful video btw. How boxy is that downtube in real life? depending on the video, it can look like the least aero shape one could come up with, but other times, it's not even noticeable.

That's interesting. can you please link to your OSPW? On the er9, if you run 11-34 (native) or 11-36 (with a small cage extender), in small small, there's a lot of chain slack. Mind you, the app has "gear protection" that prevents that, plus you shouldn't cross chain, but if the OSPW acts as some de facto clutch, it becomes a lot less useless as an upgrade, at which point i'm curious to try. And I agree w you, i'm not paying 500$ for that farce.
It then becomes a question of whether there's an OSPW option for the er9/x.
