Is it a stem provided by Velobuild ?
Is it carbon and did you weight it ?

Hi everyone,
I would like to replace the screws of this brakes by titanium screws:

Could someone please tell me how long should be the M6 brake's screws? I don't have access to my bike now to check.

For some reason...the forum can't/won't load my YouTube URL. My apologies if this is against the rules.
Here is the title of the video: I May Have A Problem - Dengfu R12 First Look

A couple of other thoughts:
1. This was my first time building up a hydraulic disc brake frameset. It absolutely was AWFUL and thankfully all the learning lessons means that I could probably build my next disc bike in a single day....rather than over four days 

2. What took the longest during the process was undoubtably routing the cables and bleeding the brakes. And that's including using the Park Took internal cable routing guide tools as well as a legitimate brake bleed kit. While routing from the calipers to the lever is easier...next time I'd rather start from the levers. I initially had some brake oil leak from the levers so I'd rather have that setup properly first.

3. Having now built 3 bikes in the span of just over one year, I've learned that you really have to take your time. Watch as many YouTube tutorials as you can and don't skip or fast forward like I did haha. I originally overlooked the "burping" of the levers by tilting the bike up/down at 45 degree angles.

I'll upload a couple of finished photos later today.

And here is the final build.

The decals/logo are my own design and I painted the frame at home myself: 3 coats of Dupi-Color Special Effex metallic paint and 3 coats of Spray Max 2K clearcoat. Wanted a little sparkle and protection while maintaining the "raw carbon" showing through.

The Hyper 65 wheels are intended for my Winspace T1500, but these will do until my other wheels arrive.

I'm building the 177 as I type this LoL. So far there are tangible differences between my Dengfu R12 and VeloBuild 177:

1. The EPS latex molding that VeloBuild uses on the 177 makes a HUGE difference when routing cables though the frame. No rough edges for the cables to catch on.

2. Velobuild seems to have put more "thought and care" into frame accessibility for cable management.

3. Paint quality is good although no real world tests yet obviously. Granted I did paint my Dengfu at home, but the VeloBuild paint is obviously better.

4. Overall VeloBuild paid more attention to smaller details. Dealing with them felt more like they were actually bike enthusiasts rather than just a company wanting to sell me a generic frame.

My first impressions video on the 177 will be later this week. I'll keep everyone posted
