Hey peeps :D
Been reading this thread for quite some time and I think it's time to get serious about building my own bike :D So much useful information here, thank you all for posting/sharing!
I have quite a few questions and I thought you might be able to help.

First of all, I'm about 172cm (5'8"-ish) tall- ~78cm inseam. I was very sure about ordering in a size S at first but after reading through some of your choices, I'm quite unsure about it. Of course you don't know my other measurements, but if maybe somebody could give some inputs I'd be incredibly happy (don't want to order the wrong size xD)

Second (less frame specific), I don't really know what depth wheel would be optimal. I'd be racing rolling to hilly triathlons and am quite light myself, so worried about winds and weight. I was thinking about 60mm, is that reasonable (SAT C60 DB PRO NxT SL2 maybe :D)

Third, and here I'm completely lost in the best way possible: The paint of the bike frame. I was quite sure about ordering a chameleon color, but hot diggity dog, the ice break color way looks so sick in some pictures posted here! Has anybody ordered one in purple or white or blue and could tell me if they think it's worth it?

Thank you again for all the information already posted here, helping me so much, really excited about this project!

I ran the 82mm Front and Disc Wheel in the back and hab no Wind Problems at all. Very stabile bike and no need to worry about. If you want to make sure to be Safe on very Windy days get a cheap low Profile Front Wheel as spare.

The winow Cockpit is definetly a good and valuble add-on. More stabiliy due to higher sides at the arm Cups and way more Aero than Standard.

In regard to the colour See the picture above. I have now Chamäleon Black, chameloen White and iced red metallic. Im my opinion White chameleon is very Nice. It comes with a Little Pearlescents / Pearl White effect.
Iced red also beautiful, the black looks nice but has a Little Bit of a structure with it, that makes it not perfectly even.

Oh and one I forgot: Those of you who got the winow bars or extension, do you think it makes a huge difference? And would it be a big PITA to switch it out later? (I'm assuming it is)

Answering your other questions, my bike has a purple chameleon paint job (the color shift is quite subtle), and I’m really happy with the result.

I’ve purchased the Winow aerobars, but I haven’t installed them yet. You’ll definitely need the angled spacers, because the original aerobars are 15° while the Winow ones are 0°. The blocks haven’t arrived yet, so I haven’t set them up, but since I’m running a Shimano Di2 system (which has a fair amount of cabling), I don't think the swap will be too difficult.

As for the wheels, I’m currently running 60mm, but here where I live in Italy, I switch to 40mm when it’s windy. I’m quite light, and the wind tends to blow me all over the road.

Re: VeloBuild VB-TT-023 I once asked if there was a price difference without the bar and there was. Maybe $60 less? This was towards the end of last year.

Re: VeloBuild VB-TT-023 After being sold on time trial riding for a while, I wanted to switch from rim brakes to disc brakes.
After reading a lot on this forum, I decided to go for the Velobuild.
I ordered through the Velobuild website after Chris checked the sizing.
I chose a size S.
I'm 176cm tall with an inseam of 80cm.
My saddle height is 70.9mm from the center of the crankset (165mm).
I have quite short legs, and that became apparent when I unpacked it and tried to assemble it.
The seatpost definitely needs to be shortened.

The frame was delivered super fast within 14 days of ordering, and the box was completely intact and undamaged.
After unpacking, I encountered my first setback:
the top tube bolts
I hadn't asked for this, and it wasn't visible in the photos on the website.
I ask Chris about my problem he would change the pictures on the website.
Everything else was very well packed,
and all the parts were complete.

Parts list :
Frame: Velobuild TT size S
Shifters: Sram s900 with leap components
Sram Force E1 Derailleur
Sram blips with leap components
Evosid cranks 165mm with 58t
Sram Force e1 flattop chain
Sram Force e1 10/30
Cema Bottombracket t47
Aerocoach ascalon cockpit extensions
Front Wheel Aerocoach Titan 100mm with Conti TT
Disc Wheel Still looking for it some tips?

I'll mainly use the TT for fast time trials.
The setup will therefore be 1x12.

I started building.
I started by spraying all the bolts black.
This should actually be standard.

After shortening the fork, I discovered the first problem.
The included expander plug was too long, or was it simply a dirty fork?
The solution: I installed a shorter expander, 26mm instead of 45mm.

When I had the carbon stem in my hands, I already had my doubts about its strength.
After reading on the forum, I knew this was a common problem.
After receiving the frame, I immediately emailed Chris to ask why I hadn't received the alloy stem, even though it was listed on the website.
Unfortunately, because of the holidays, this took three weeks to send. Its on my way atm.
I couldnt wait to build this monster ,So I tried the carbon stem.
I did it like this: I applied a thin layer of carbon paste to the base bar.
I tightened the expander bolt 2nm and the top bolts to 5NM, so I could then tighten the bottom bolts according to Chris's advice 5nm
Unfortunately, the stem failed at 2NM and split in two at the front.
I'm glad the aluminum stem is on its way to me.
Fortunately, Chris is easily accessible and acts quickly, which I'm happy about.
I'm waiting for the alloy stem this week so I can continue with this monster.
I can't wait to ride it.

Annyone Else had problems with the carbon stem?

Will be continue..
