Bought a set of wheels from Zen and I couldn't be happier.
The rims are the U shape, 60mm depth, normal weight version, 51mm carbon spokes.
The wheels came out beautiful and without any defects, weight is around 1400g as advertised, and I had the option to customize the paint style and decals.

Had no trouble with shipping, they sent them out on time, and most of all customer service was impeccable.
Texted with them on WhatsApp and they always replied as soon as possible, even at late hours for them in China.
Overall couldn't be more satisfied, I'll report back after 100km as well but I can't wait to try them out.

Absolutely recommend them, especially for their professionalism and excellent customer service!

I had to get used to the modern, more forward riding position, and after about two months it felt fine. I adjusted all my bikes that way. However, this size L frame is simply too short for my height (186cm/90cm), even with a 120 mm stem, and there is also significant toe overlap.
As for the ride behaviour, it is very stiff and responsive, but definitely not a comfortable bike (I ride it with 65 mm high carbon wheels with carbon spokes).
I plan to buy the Mondince aero frame FM126 in size 58 once it becomes available.

Thank you for the insight, I asked because it would actually be useful for me if the bike has a steeper seat angle, as I'm trying to build a bike to use for normal riding but also occasional triathlon races races with aero bars. So the seat angle being steeper than advertised could possibly allow me to have a better aero positioning.

Be careful with the geometry of this frame.

The seat angle is not 73.5º as stated in the Winow size chart – it's much steeper, more like a time trial bike, over 80º. So the higher you set your seatpost, the shorter the effective top tube becomes.

Normally, I ride a size 58 with a 110 mm stem. I chose this Winow in size L (56) and paired it with a 120 mm handlebar, thinking that if I moved the saddle 1 cm backwards, it would be fine. But this is impossible on this frame. The saddle is positioned as shown in the photo, and I'm still 2 cm short.

Even though the Winow is supposed to be available in a XL frame size, it doesn't really solve the problem — it only adds about 1 cm to the rear of the bike, which doesn't help with my issue.

Are you still positive about this after more riding? Would you say the angle is really that steep?

Hello guys, I'm looking for a frame to use as an aero bike on training/recreational rides, and also for some occasional triathlon races (nothing too crazy, I wanna have fun and challenge myself, otherwise I would get a proper TT bike).
So I was looking for a geometry kind of in the middle of not being too aggressive but still allowing a decent aero position; I'm planning to put an Spcycle handlebar with integrated aero bars.

Browsing the forum I found these frames:

Winow WR054
TanTan TT-X65
VeloBuild VB-R-368

Do you guys have any other suggestions for frames that might fit my research? Or if you wanna comment on the ones I found it would be appreciated too! For example I know the VeloBuild might be what I'm looking for in terms of geometry but I'm a bit confused as to what they have done with the headset. So any insight is appreciated, thanks a lot!!

you posted in gravel bike section

I can't believe it, I've always browsed this forum on the road bike section and the one time I post I do it on the wrong section!
I'm sorry, browsing from my phone I must have clicked on the wrong section without noticing!

Hello! What's the matter? Did I post in the wrong section or is there anything about the frames? Any help is appreciated
