Got the bike more or less completely assembled, just missing a few non-vital parts like bar tape and proper bottle Cages. Here's some findings.

- The headset dust cover/top cap is hitting the frame (even with the C clip included). I made a small plastic C-shaped 0.5mm thick spacer and that seems to do the trick so it clears the frame (at least so far).

- The fork just slightly scrapes the bottom of the head tube (see attached picture). I'm guessing it might be hard to space this out, so probably going to sand the bottom of the head tube a bit so it goes more clear of the fork.

- The chain stay issue that Patrick also showed seems to be also present with Ultegra R8150 rear derailleur - I have not played around with chain length yet to see if that might change things (if someone is more experienced than me with B-screw vs. pulley wheel to cog clearance vs. B-screw I'm open for input). Basically you seem forced to have the B-screw tightened more than needed for the RD cage not to hit the chain stay. I couldn't get the ZTTO SLR Gen 3 11-32 cassette to shift well (it shifts OK on two other bikes here) as the cage cannot be moved close to the cassette, which seems pretty important for that cassette to work. I've put on an Ultegra 11-30 now and that seems to be better in the stand at least. You can see on the attached pictures how close the RD cage is to the chain stay currently, yet it's still quite far from the biggest (30T) cog on the cassette. If I loosen the B-screw to bring it closer to the biggest cog it will hit the chain stay in the smallest (11T) cog.

Unless I find a good fix for that last issue it is a bit annoying as I think it's quite the oversight in the frame design - and a bit surprising considering this is not their first frame. I know they've fixed it already in at least some of the sizes, but it seems they've also shipped some frames out with this issue after they became aware of it.

Can you share a photo of the complete bike? I'm curious to see the XS frame with the wheels. I also ordered an XS, and Chris informed me that this issue with the stay has been fixed, so I hope I won't have that problem.

I didn't quite understand your issue with the headset dust cover. Are you using their handlebars?

Here's a picture - ignore the tape on the top tube, it's just to protect it from the handlebar hitting it until I get the bar tape on.

I'm using the LightCarbon HBR17 bars, but got VB to print a custom headset dust cover to fit that bar/stem - it's basically the same as the standard cover, but just with a slightly differently shaped cut-out on the top.

Congrats it is the best good looking 368 build i have seen.

Fini is right, that's a nice looking rig mtm.
Latest fitting fun and games on my ugly duckling XL.
TT sofa saddle and higher stem.
The comfort is still impressing us, and I'm loving the reach.
Speed feels easy to maintain
Climbs nicely seated.
Going to take the FL1 out later for a comparison.

looks really good! what's the final weight (i see some lightweight components so i'm guessing you tried to reduce as much as possible, 8.2/8.5kg?

are these wheels 45s? maybe with some deeper ones it would look less big  ;D

Lolz, they're 35's off my FL1.
Wheel tech seems to be changing so fast at the moment that I'm waiting for a bit before committing to a new pair.

The pictured setup was pretty much bang on 8.0 kg. With the Ultegra cassette on now it must be at least 100 g more. It'll get some lighter pedals on in the future and I'm also thinking whether it should get some lighter wheels (should be able to shave 300-400 g and keep the depth) plus small weight tweaks here and there like lighter fork steerer expander and maybe lighter crank (though I do like the sleekness of the Xcadey crank). Hitting 7.5 kg should be possible (though really not that important in pancake flat Denmark).

By the way whats´s the total weight of both of your XL builds?

Still waiting for wheels on brother's bike, Evri is absolutely useless >:( But that won't be particularly light as he's about 110kg so Clydesdale build.

My black one is about 8.3 maybe(I did weigh it but am old and forgetful) as pictured. Apart from the wheels (1040g) I haven't got anything Weightweenie on it I don't think.
Hydraulic cable 11s 105 shifters
GRX mech with 11 42 cassette
Force crank and ring 560g.
Think I worked out that if I moved my FL1 components across it would have been 7.4ish kgs, but weight wasn't the object of the exercise.
Seem to remember some of the TdF Ridley's were just over 8kgs so that was roughly the target.

8.3 without weight weenies parts is impressive because ridley noah from Unox was 8.2 kg for size medium (with 1600 g wheels). I thought they were going to be 8.5+kg for that size.

Handmade in Italy   ;D ;D

Seller seems to be very close to me, from what i've seen he sells chinese OEM frames with custom painting as fully built bikes, no idea on pricing. Might be worth it to go there and check out the 368 in person if he has a shop.

recently ordered one. The final price in Italy, painted and with a 5-year warranty, is around €2,000. I bought this aerodynamic bike to use only in circuit races, in a “super-aero” setup (aero bottles, 65 mm wheels, aero helmet, aero chainring, Koegel pulley wheels for time trials). I can send photos in January when it’s ready and fully assembled.  8)

In the meantime, a whole new world opened up for me: I pushed ChatGPT and Gemini hard to figure out where the frame actually comes from. I knew it was Chinese, but I didn’t know from where. That’s how I discovered Veloplus and this forum.  :)

Unfortunately, not great news for me. The seller claimed: “100% Toray 1100S” and 925 grams in size M. So I thought: hey, maybe it uses the same mold but is made in another factory with “higher-grade carbon.” But after further research, it seems that was just an illusion. Most likely he buys it from Veloplus, repaints it, and resells it.

Which is actually fine — custom paint, assembly, warranty, local support in Italy — all good. But lying so much about the carbon quality and the frame weight is not a good move.  :(

When I pick up the frame, I’ll talk to him calmly about it. Then I'll forget this unpleasant story and focus on pushing this "beast" as hard as possible   8)
