If you are okay with buying used, that would be the cheapest way to get a good wheelset. I wouldn't buy a new, cheapest wheelset instead I will look for a used one in the same price. The wheelset makes huge difference in the way bike rides. In the budget range, DT Swiss' OEM wheels are good. Many bikes comes with it pre-built and people upgrade them, so finding them used isn't terribly difficult or expensive. For e.g. DT Swiss C1850 Spline which is just OEM version of C1800 wheelset. I was able to snag one for $150 and its been great. Hunt 4Seasons X-Wide gravel wheelset has also served me well, but slightly expensive ($300~ used) and has gone out of tune a bit while the DT Swiss is still true. Suggest you to not get super heavy wheelset - it just sucks the fun out of a good bike.

My build  is progressing piece by piece.

As the first wheelset I will use the ENT Elite Wheels with Conti 5000 in 28mm.

What very cheap wheelset and what tires would you recommend for gravel?
What maximum tire width fits (700c) in the frame?

This information was provided to me by Email from Chris: Tire clearance 700x45C or 27.5erx2.1

It's me again.
The cabeling in the handlebars and stem has now worked, but there is a problem to lay the 4 cables in the area of the headset.
Currently I lay the cables from the handlebars through the compression ring into the frame to the brakes and the derailleurs and then try to install the fork. I try 2 cables left and 2 right from the fork tube to pass, but it does not work. Since the cables from Jagwire Pro Set are very rigid, I have enormous problems to install the fork and at the same time compression ring.
Does anyone have tips or a video what this explains well?

You will have a tough time internally routing Jagwire compressionless housing through the separate stem handlebar combo. I shared some of my experiences in this VB-R-099 thread
http://chinertown.com/index.php/topic,3102.msg34848.html#msg34848
The tight bending radius will also cause more cable friction for an all mechanical setup, which will likely impact performance of brakes or shifting.
You might consider a semi-internal setup, guiding the cables outside the bar and underneath the stem and then entering the internal routing through a modified headset cover (like FSA No. 69 or mechanical modification of the spacers).

I have the exact same setup and routing is a nightmare though I gave up on Jagwire in the end. Despite that, the shifting is exceedingly smooth. It is Ultegra R6800 and when I compare it with my Fuji with external cabling and 105 R7000, Ultegra has faster, smoother shifts.

May be it its there but I can't find a video explaining the whole process. Here is what I did though:

1. Keep cables as long as you can. Finish ICR thru handle and stem and tighten the stem bolts..
2. Insert fork in the frame and with help of Velcro straps, tighten it to frame so it does no slide down.
3. Insert C ring. Insert dust cap without fail.
4. Take someone's help or if you can manage on your own - hold the handle/stem above fork steerer and start passing all the cables thru C ring into the frame and fork.
5. Front brake is easy. For rear portion, it is trial and error, fiddling and cursing for hours until all the cables have passed through respective outlets. There is no other way at least I don't know.
6. Front derailleur cable routing is tricky. You can route the cable above BB spindle or below. There is enough space in the frame to route it above the spindle but I found out going under the spindle is easier to bend the cable.
7. Once all cables have passed thru, assemble spacers and tighten stem to steerer.
8. If the bends in cable outer were reasonably fine, you should have no problem inserting cable inners.
9. Again, trial and error on shifting and braking action.

It is important to have proper cable ends inserted on shifter side. Without those you will have hard time inserting cable inners. Once you have successfully passed the inners, have one more set of cable ends handy for the other end.

Thanks! I'm using a Wheels Manufacturing internally threaded pressfit BB. Haven't thought much about the logic of the statement above in truth, just passed on what VB mentioned. May switch out the BB instead of replacing the bearings and can report back if it makes a difference.

Hi

Did you solve the issue with 34/50 crankset rubbing?

Hi

Did you solve the issue with 34/50 crankset rubbing?

Yes, I added 3 or 4 plastic BB spacers on the drive side and that did the trick. Initially I added one less because the small ring wasn't rubbing but didn't take into account flex when under load so remember to add an extra one if possible.

Cool, thanks.
Is the chain line still ok after adding all the spacers?

Yup seems to be

Question to all GF-002 owners, regarding the headset (once again):
Using the compression ring and headtube cover that came with my frame leaves a significant gap between the headtube and the headtube cover (2.4 to 2.6mm),
The compression ring seems to be the "updated" version that is supposed to improve headset play with some of the road frame models.
Not sure about the headtube cover version, though, it has holes to align with the compression plug (while the updated version does not have pins).

Can anybody comment about gap between headtube and cover and about that hardware that came with your frame?
Nothing against Velobuild, but the headset topic is so annoying and the constant change of design and hardware makes it a total mess...

[coffeebreak]

The gap seems okay.

[bichler.bua]

The gap seems okay.

Per Velobuild, Chris: The gap should be around 1mm
So clearly 2.5mm is too large of a gap. But than the conversation with Chris dropped, no more feedback from them - back at "customer service" when ordering B2C from China...

[carbonazza]

Whatever Chris says, the cover should ideally seat flush with the headtube.
And packed with grease.
Some cover models even have an integrated rubber sleeve.
Otherwise you're left with an open door for rain or cleaning water, that will  kill prematurely the headset bearings.

Aren't there two bearings heights for 1.5".
It is not the first time such kind of picture pops up in the forum

[TidyDinosaur]

Yeah, that gap is way too big. Will ruin the bearings in no time.

Velobuild supplied two identical bearings, both 7mm height. So no risk to swap them, like on Carbonda (6.5mm vs. 7mm)...
The top bearing is properly mounted, confirmed twice and also by measuring the individual dimensions.
As usual, this leaves the Velobuild customer with figuring out the headset adjustment on his own...
