Thanks for elaborating!

Thanks for all the pictures l45er! A great looking bike. Lovely result.

Do you have any tire clearance pictures of the front fork?

Didnt know the indexing of the RD would work with 12sp Shimano.

Is the FD maxed out in terms of how high it can be mounted in FD-mount?

And can the FD handle the 16 tooth difference between the front chainrings?

How is the pulleywheels of the RD handling the smaller rollers in the chain?

Lovely bike. Congrats, but never seen that level of drivetrain mixing  ;D

How does it shift?

Make sure you tell that to Velobuild. More people saying that can only mean change for the better.

Nice. Thanks for info.

Which BB did you buy?

7
This looks bloody lovely.

Repectable weights, ROUND seatpost, External cables on the handlebars, so they are easy to change. No focus on bikepacking with way to many mounts and fairly road focused geometry.

Is the c-ring plastic or aluminium? Hard to spot on the pictures.

Also interested to see how the BBRight bottom bracket will pan out.

Great frame. Let us know how the build goes!

Im pretty sure that bike in the pictures is the real deal.

Check this video from GC performance:

The C Ring is way too stiff since its just massive. Due to that, the headset needs to be compressed with a lot higher force than its made for in order to cause the elastic deformation of the C clip which is needed to close the gap between inner bearing ring and fork tube (which is what it is all about in order to avoid headset play).
I guess this is why many people complain about headset play even though they tightened everything. Also the stated problems with de-formed top caps might be a result of the high compression forces.

Good observations and definitely true. I cant believe so many Chinese framesets use this C-ring design. To stiff and too open. All this compression on this C-ring will just end up scoring your headset bearings.

Please see the attachment. thank you



That C-ring will cause you trouble. It too open and too stiff. You will have a bad time, guaranteed. It'll never feel tight, and it will start to creek.

Please offer a better solution SP Cycle.

Nice !

 Did you just pass the brake cable  only ??

Also could you post the link for the spacer you used ?

Thanks

Thanks. I use SRAM AXS Etap so only brake cables, yes. I think this would be to tight for mechanical shifting (4 cables). Older cabled Di2 should be fine.

The spacer is custom, so unfortunately you cant buy it. I posted the dimensions if you know someone that can make one for you.

I have had some increasing issues with my headset recently. Lots of creaking no matter what I did.
After inspection is was clear that the C-ring was the culprit (as others have discovered). It just doesn't have enough wrap-around angle. You can see on the picture how much pressure is on the edges of the c-ring, causing rubbing and creaking.

I know Velobuild have made an updated version that might be better, but i wanted a significantly better version. My idea was to use the c-ring from the Specialized SL7 (the replacement after recall). It seems like a good design that wraps all the way around (95%) but doesnt need the hydraulic lines to be broken. The main problem is that it is made for a Ø40.5mm inner dimension bearing. Its also too thin to be a direct replacement.

Sourcing the SL7 c-ring (ID: s212500016) was a bit of a pain. Specialized was slow to send it to my local dealer (3 weeks). On top of that the price was high (35$ + shipping) and the customer service was terrible. The holy trifecta of a shit deal - but it worked out in the end.

I work in engineering so I called in favor to get the c-ring lathed down to Ø40 (a little tricky with an open ring) and I got a small spacer made for purpose. Spacer measurements are Ø30.9 x Ø28.9 x 2mm (stainless steel). Fits just as intended with the one piece handlebar. I have gone for a couple of rides now and I cant get a single creak out of the headset no mater how much I pull and twist on the bars.

Dear Velobuild - Please spend the extra $10-15 dollars on a proper c-ring design like this one. It is sooo much better. 

Original C-ring. Waaay to open.


You can see that so much of the load is going through the edge of the ring.


Lathed c-ring from SL7 + spacer


Spacer needs to be very small to not squeze the cables.



Gap between frame and cover is pretty good. You can shave of a couple of 0.1mm if you want it tight.

+1 on the Specialized expander.

Lighter than the chinese ones while still providing good length and grip.

VeloBuild just announced a new CX frame. Tempted to switch over from my newly built GF-002 to the new CX-002 for the more race oriented geometry.

This is right up my ally. I think they really read the marked well on this one. There is a gap in the (chinese frame) marked for this type of bike.

I've done 6000+ km on that bottom bracket in the last year. Gravel and road. No problems so far.
