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'm 1,74m and my saddles is 73cm from BB. I have a size S. Could use a M ? I think so.. but i like to use my S.

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.

Why the Trek branding? Stuff like this is what gives Chinese manufacturers a bad wrap.

I understand your point that is a "wrong" pciture but I really do like the optics of it. Having nothing on it looks a little empty and the logos are already there...

Thank you for sharing, very helpful! With spacers do you mean the bracket/block thingy, or the spacer shaped one for like 10$?

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.

For thw winow aerobars, what garmin mount do you use?

I noticed the part has two holes underneath for a mount, but it's not easy to find one that fits. I saw that Winow sells a version with two clamps that attach to the aerobar extensions.

today  I'm using a generic road bike mount screwed into the central hole on the original plate of the bike kit.

I like a plain bike myself. But you could come up with custom branding or have literally anything else that is not copying a manufacturer that you didn't buy the frame from.

yeah I was more worried about weight actually (I know, I know, it's a TT bike, weight barely matters, but I'm still looking at over 2k of elevation in 180km). Thinking about going higher than 60mm now for sure :)

Which Triathlon are you doing? Setting mine up for Ironman Wales (2,500m elevation) with 50mm deep wheels @1350g. Trying a lighter setup this year vs the 88/60 combo I was running before. If you live in a windy area, you get used to being pushed around by the wind, but can imagine it being a daunting experience if you’ve never cycled in such conditions.

I'm doing the 70.3 in Rapperswil (Switzerland) a second time this year and am planning on doing the full IM in Thun sometime in the future :) Not quite as hilly as your course, but still over 2'050m elevation :D

Had some rather deep-section wheels on my road bike and already felt the wind (like when a truck drove by). So the decision is probably between a 60/60 or a 88/60 setup, staying open about upgrading to a disc wheel later :)

Hi everyone,

I’ve finally installed the new Winow aerobars to replace the original ones. Overall, the process is relatively straightforward.

Disassembly:

First, you remove the stock aerobars.

Note: If your setup involves cables like my Shimano Di2, you’ll need to disassemble the buttons and be very careful with the electronic wires. If you’re using SRAM or something similar, you can just proceed with removing the bars.

The Angled Blocks: Next, you’ll need to mount the Winow angled blocks (I went with the 20° version). One thing to note: I expected these blocks to be larger to provide a wider contact patch with the aerobar, but they are actually quite small and narrow. However, once everything is tightened down, the system feels secure (though it still feels like it could be improved).

Mounting the Aerobars: Finally, you mount the aerobar onto the angled block. Since both the blocks and the bars are from Winow, I expected the bolt holes to align more perfectly. There are plenty of mounting options to fine-tune your fit, which is great. But, depending on the position you choose, you might only be able to secure two bolts—I personally feel that three would have been better for extra security.

The Challenges: My biggest struggle was the Di2 cables, which are at their length limit, restricting how much I can adjust the position. Also, I had a bit of a hard time installing the Shimano bar-end buttons. The tip of the aerobar was slightly narrower than standard, making it difficult to plug the buttons in.

Guys, can you tell me who installed the systems with the di2 battery, how did you fix it? Maybe there is some kind of 3d printable model to keep the battery in the seatpost, or some other options.
So far, I've only ordered a frame, I'm choosing a groupset, I'm leaning towards the LTWOO eRX-TT, but I don't know if I can fix the battery from it inside.

Why not just get sram and avoid all the wiring headache? Otherwise performance is the same.

I just foampad the battery and put it into the seatpost. Nothing moved there.

Does anybody know (or could measure) the (preferably inner) diameter of the aerobar (extensions)? Need to know because I have to choose when buying the Leap Blip holders xD
Is it also similar to the Winow ones if I'd want to upgrade? :)

Does anyone have experience with stacking spacers on this cockpit?
I love the frame, but think the winow will be better sizing for me due to the taller stack. I wondered if there was a limitation or anything to be aware of with stacking spacers to potentially raise the front end? I have seen you get get bridging plates to help with this, but didn’t know if there were any limitations or issues with going too high?
