Heyo guys,
long time no see.

I have been riding my vb-218 since last september pretty much exclusively.
I just got home from a ride yesterday and today I wanted to hop on and take it for a spin, but I observed the following: see the pic.

there is a small crack in the carbon near the lower seatpost screw. I have not changed my saddleheight in quite a while and tightened it with 3-4nm only. So im guessing the frame is gone then?

I rode in around 0 degrees c in winter and my bike made some weird noises in those very cold temps. But i thaught that was the saddle rails or something like that.

How did you repair yours sebastian? And would you mind giving me a crashcourse in your trades :D? Also you think this is a warranty claim worthy case?

Un-Tighten an Re-Tighten the seat clamp screws slowly and see if you can make out any movement in the crack.
It's a bit of a weird spot because it appears to be below where the seatpost wedge actually expands. Also, examine the inside for cracks.

If you're sure that it's actually a structural crack, definitely make a warranty claim with VB.
Mine was replaced under warranty. Chris asked me to sand away the paint to expose the crack. But that shouldn't be necessary with yours.

Re: Velobuild VB-R-218 Once again it’s good to see that VB at least stand behind their warranty.
But I must say, all the issues in this thread do not fill me with confidence. Not sure I would buy from VB again, to be honest.

Re: Velobuild VB-R-218 I’ve ridden mine for around 1500km / 930 miles now and no issues. I think it’s solid. Also, the repaired seat post clamping area holds up totally fine. That’s why out of pure laziness I haven’t bothered to build up the replacement frame. It’s hanging on my wall.

I’ve been using this bike on the trainer as well for several weeks now including sprints and FTP tests and the likes. It holds up fine. If anything it’s actually quieter than my Ridley before.

I got a superlight monobloc cassette from SROAD on order plus a set of Bontrager Speed Stop pro brakes. That will shed almost another 200g from this build.

Re: Velobuild VB-R-218 Just an update on tire clearance on the rim brake frame.
I built a custom set of 60mm deep clinchers for this bike. The rims are around 30mm wide - slightly less at the brake track. Internal width is 22.5mm. A 25c Vittoria Corsa measures almost 28.5mm on these rims. As you can see, there’s still plenty of clearance on fork and brake.

No pics from the rear as I had the bike in the trainer. But there’s still plenty of clearance at the chainstays as well. I reckon you could just about get 32s in there if you wanted. Actual measured width, that is.
For me 28mm is all the width I ever need on a road bike.

Around 70psi on the front and 72 at the back. Sometimes slightly less if I ride rough stuff like cobbles much.

Sorry. Need to correct myself here. It’s 80-82 at the rear and 72-75 in the front. Forgive me.  I’m not using psi much. For me it’s all about pressure in bars.

80 bar =1160.3 psi   

If the earlier poster followed the recommendation in psi & managed to get past 1000psi, then please post the brand of the tire & tubes used as it would solve all our pinch flat issues

I did have a funny image in my head of someone pumping their tire and it slowly getting larger & filling up their garage  ;D

You’re probably just mocking me now. But those figures are in psi. In bars that would be 5 up front and around 5.5 at the rear.

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.

Re: Velobuild VB-R-218 The frame does not have a port in the downtube. Just like the current Dogma F. So you would have to get a handlebar junction box. I don’t know however if this handlebar is compatible with Shimanos bar end junction box. Maybe someone else has built this thing with Di2?

you also however run into the risk of toe overlap.

I’ve been worried about toe overlap in the past as well. However in practice I found it to be a non issue. Even on a commuter bike I had that had severe toe overlap because of the full length fender on the front it became second nature to always have the feet in the vertical position during very slow manoeuvring at a red light for instance. And during riding it obviously doesn’t matter.

Re: Elves Falath EVO 2023

No one has posted this yet: Cam Nicholls' build video for the Elves Falath.
Seems like the quality and finishing of frame and fork are very good. No issues during the build process.
Frame weight is a little underwhelming at 1300g for a size 54.
Final build weight with fairly lightweight parts (without pedals) is 7.9kg which puts it more or less where to be expected for a modern chunky aero bike.

They're also saying that the frameset will be delivered with 30mm worth of spacers. Too bad they themselves didn't have any so we still don't know what that solution is gonna look like.
