Hi Guys,
I would like to buy this frame.
I can't understand where is the Di2 battery?
Can you help me?


thanks

There’s a screw on cover beneath the BB. The frame comes with a Di2 battery holder that can be attached to that BB cover.

Finished my build and just went for a short ride to check on everything. Rides very nicely, very stiff (I might change the rear tire from 25mm to 28mm to increase comfort). Overall I'm very happy with it and for the cost I cannot complain (warning: new toy syndrome). The fit is also nice, as I was afraid the frame could be too small. But the aero spacers and saddle setback make up for it.  I'm 188cm tall with a 92cm inseam and long arms, got the XL Frame. I haven't decided on the final bike fit, so I still have 15mm 3d printed spacers on top - thanks to the stranger who designed these and put them on thingiverse! I'll also put some TPU on my 3d printer this weekend and see if I can draw up some grommets for the frame openings that I don’t need due to the electronic shifting and a seat post gasket.

The only issue I have not solved yet is some disc brake rubbing on the rear brake that I cannot get rid of at the moment. Possibly due to misaligned (unfaced) brake mounting points. I went with post mount brakes as I got the Sram Red groupset for 600€ cheaper than flat mount, so I had to use adapters that increase the distance between the calliper and the frame. Not sure if that worsens the issue. I might want to exchange the callipers to flat mount. Does anyone know if changing to flat mount callipers helps with the disc brake rubbing? Or does anyone have experience with DIY facing the brake mounts?

Nice build Matt what wheels are those I dig the finish and that paint is sparkly!!! Definitely go to a shop and get the brake mounts faced to help with the rubbing!

That’s what I was gonna suggest. Your postmount calipers should be fine. The misalignment is most likely due to uneven brake mounts.

Nice bike! I dig the paintjob.

so many VB frames here but not a single review of VB wheels.

in fact, Patrick Lino had these wheels (the 38mm version) on his Velobuild 177, but he wasn't overly impressed by their ride feel and the heavy weight.

Check it out here:

Thank you very much for the picture. Apparently I have mistaken you for someone who had frame cracking at the seat post screws, haha. But thanks a ton for your effort

That was me. I got my seatpost set up to a seat height of approx 81.5cm. The seat tube is 54cm tall on my XXL frame. I dunno how long exactly the seatpost is but I marked and measured it and it's inserted around 10cm. I'm pretty sure though that my frame cracked upon the first installing of the seatpost when torqued the bolts up to 4nm. At least I heard a cracking noise then. Actual cracks only showed after the second ride, though. But ever since I repaired it, it holds up fine. I still haven't built up my replacement frame because I see no reason to do so.

Re: Velobuild VB-R-218 Quick update on my end:
I noticed in the long run, that I routed my rear brake housing a bit too short, causing a kink in the housing at the headset and bad rear brake action.
So I needed to put in new housing and therefore take apart the whole bike basically.
So I decided to finally build up the replacement frame instead just for the sake of trying it. Also, I switched the groupset from Campy 11sp Centaur to 12sp Record - sourced the parts slightly used for cheap. Mechanical rim brake stuff isn't really worth much any more in this day and age.

The build turned out very nice. The seatpost clamping area holds up. The BB did not cause me any trouble. The cups screwed right in, the cranks spin smoothly.
Headtube bearing seats were slightly less tight on this frame, but the surface was a lot nicer finished. On my first frame it looked kinda rough. On this, it seems it was finished with some kind of lacquer coating. Again, I needed to drill the rear brake cable exit hole at the top tube. I explicitly told Chris at VB to make sure it's properly sized and he promised to take care of it. But alas, I guess stuff like this is just something you need to be prepared to do with Chiner frames.

I got another one of the superlight SROAD cassettes. A 12sp 11-32 cassette made from one block of steel, weighing about 215g. They only had it in stock in rainbow colors. Wouldn't have been my favorite choice but now that it's on the bike, I quite like it. I found these one piece cassettes to transfer more noise, especially in combination with deep wheels. So if you like your drivetrain to be dead silent, they might not be the best choice.

The build turned out very nice. I really like the bike. I dropped some weight in the process. This build as pictured, including all accessories (without Wahoo, bottles and saddle bag of course) does now weigh 7.6kg for the biggest available frame size (XXL/54).

Thanks also to madmax for giving me setup tips with Record 12sp.

Re: Velobuild VB-R-218 Since this thread is back from the dead, I thought I might as well give an update. More than 8000k done. No issues. Still the first headset with no signs of wear which is a pleasant surprise.  I wasn’t too confident in those bearings. This is the bike with the race wheels on: 60mm deep/1300g with 28mm tubulars. These feel soo nice when accelerating and the cornering feel is insane. I’m still in love with the handling of this frame and the super quick steering response.
