I felt tempted to build a Titanium gravel bike after checking the offers of on Aliexpress, I decided to pull the trigger on following PYTitans frame in October:
https://www.aliexpress.com/item/4001085459477.html?spm=a2g0s.12269583.0.0.7cfc1333bqHRlA
It took until beginning of January to arrive, but the seller was communicating clearly it would take more than two months for the frame to be ready to ship. Communication with the seller was good.
The weight including seat post clamp is just shy of 1600g.
Below some pictures of the frame.

Here the build details:
- PYTitans Gravel frame Size 52
- Zerace RX4 crankset and BB with 42 Tooth
- Sigeyi Power meter for SRAM
- Juintech F1 break calipers
- OG Evkin: Seatpost, Stem, Handlebar and Headset
- Toseek Saddle (Prologo copy)
- Elite Wheels 32mm/35mm with RD13 Hubs and Panaracer Gravelking SS 38mm Tubeless tires.
- Shimano 105 brifters and GRX RX812 Derailleur
- ZTTO 11-46 Casette
- Garbaruk Deraileur Cage with 15Tooth Meroca Pulley to get the 11-46 cassette to shift smoothly
Total weight including pedals, bottle cages and garmin mount: 9.2kg
First short test ride was good, now waiting for some warmer weather for a longer ride.

I get the same problem. They all load as blank pages.

Sorry for this oversight... and thank you for the tip.
It has been a while since I posted, so things may have changed.
Using IMGBB works perfectly. 8)

Looks a lovely frame :) ... Did originally order a Ti sonder Camino , but after waiting months , they cancelled my order as they had complete bikes to build rather than sell me a frameset id paid for etc months ago !!
may look closer into the Ti market

Thats a great looking build! Did you have to source your own fork or was that part of the deal with PYTitans? Paint job on it looks fantastic.

I chose a different fork from the Aliexpress seller Cwind:
https://www.aliexpress.com/item/1005003127524864.html
The quality was not as good as I hoped, I had to clean up the threads and the contact area for the flat mount calipers.
But with some elbow grease the problems were solved.
I decided to give a home made paint job a go and used the "marble" look. Automotive "Blue metallic" spray paint and a plastic foil were used to transfer the pattern to the fork.
The original matte black was sanded slightly with 800 grit sandpaper in preparation of the paint job.
To finish the surface I gave it two coats of clear 1k automotive grade lacquer.
Here is a video where I got the idea for the paint job:

Maybe a full frame paint job in the future.... ;D

Officially 42mm with a 700c wheel, this seems about correct.
My Panaracer Gravelking 38mm measures 40mm wide with my wheels and there is still plenty of space.

Awesome bike! Did you just simply get the frame in their Aliexpress store or did you come up with your own design?
-
Nice build, hopefully I'll have something to share in the next few months. Who did you but the brakes from? I'm also in the market for some GT-F's.

I ordered the standard frame off of Ali, then they sent me the drawing to check.
All looked good so I gave them the green light for production. So far nothing I would have changed, the build went really smooth.

The breaks work perfectly, so I can definitely recommend thr Juintech F1, not sure if the more expensive GT-Fs are really necessary.
I got them from Aliexpress as most parts, the shop is called „Cycling House“

After 2600km the bike is still going strong.
The only modification I am considering is replacing the Zrace RX4 crankset with the Racework N1 carbon crankset. The DUB Bottombracket starts to get noisy again, it took me already some time to get it right when I built the bike.
A standard BSA with 24mm spindle may be the better option due to the increased bearing size?

Here some pictures from last week Nova Eroica Switzerland, where the bike was really put to the test on some technical downhill sections. The Juintech F1 Hydromechhanical discs did well, even they were very hot at the end of the descent.

Hey Chris lovely build. I am refreshing this post as I would like to ask specifically about the og evkin seatpost. Is it comfortable? I currently have the elite one seatpost and its great because it has quite a nice flex so it's perfect for gravel in terms of compliance. Only problem is that with my new saddle without cutout it is almost impossible to adjust it because of no access to the top sestclamp bolt. That's why I wanna get the og evkin seatpost and wonder if it is comfortable and good at damping vibrations and maybe even some nice flex like the elita one for. Would love to get your input

Hello @kubackje
Sorry for the late response, I have not been very active on bike builds in the past few months...
I was never completely happy with the original seat post, the fixation of the angle was not very stable until I put a lot of carbon paste inside which finally stopped the occasional slip.
Other than that the seat post was comfortable but was changed to a generic seat post with different clamp that allows 7x9mm carbon rails to be used. Comfortable and stable at the same time.
The bike is working great and I am loving the geometry and ride feel after more than 3'000km.
I like to try some new things, here the updated setup:
- PYTitans Gravel frame Size 52
- Racework N1 Carbon cranks with BSA BB an 42 Tooth chain ring
- Sigeyi Power meter
- Shimano GRX600 breaks
- OG Evkin: Stem, Handlebar and Headset
- Generic: Carbon seat post with 25mm offset for 7x9mm carbon rails
- Elita One Carbon Saddle (Prologo copy 143mm wide)
- Elite Wheels 32mm/35mm with RD13 Hubs and Panaracer Gravelking SS 38mm Tubeless tires.
- Shimano GRX600 brifters and GRX RX812 Derailleur
- ZTTO 11-46 Casette
- Garbaruk Deraileur Cage with 15Tooth Meroca Pulley to get the 11-46 cassette to shift smoothly

Hey Chris,
im looking at the same fork and looking at different bolt color but cant find any seller saying the size of those bolt and got random answers which were pretty random.
Can you tell me if those are standard M5 10mm or 15mm?
Thanks!

Hello Ostriker
The C-Wind fork uses M5x10 screws, to make it look nice I used some that are usually used for 6 bolt disc breaks.
Here an example: https://www.aliexpress.com/item/1005005495067094.html
Of course if you need to fix some rails, you may choose longer screws instead.
