Some other frames I’ve looked at include the Longteng 268D (https://www.ltbikes.com/index/products/view/id/21.html) with 1.40 stack/reach ratio, but slightly over 1000g, and the Longteng 266 (https://www.ltbikes.com/index/products/view/id/211.html) with 1.37 stack/reach ratio - but Longteng has been slow to respond after several attempts to reach them.  And the Workswell 366 (https://www.workswellbikes.com/endurance/wcb-r-366(disc-brake).html), with 1.39 stack/reach ratio, $800, but 1130g, and as mentioned above, Workswell doesn’t do custom painting.

New member here - I also have the same dilemma, and will share my thoughts.
[Edited to add LT266]

From my emails with them, they offered these in size 52:
- 366 at 1130g, US$620 for frame and fork only (seat post is extra but it's standard 27.2)
- 316 light at 950g, US$890 for frame, fork, seat post
- 316 standard at 1100g, I didn't get a price because I wasn't interested in this frame

It just so happens that the Taipei Bike Show is happening this weekend, and I will go check it out.  I know Longteng has a booth, and likely other Chinese OEMs as well.  I'll report back on anything interesting.  (Let me know if anyone has any specific requests or questions in my DMs ... but I won't take requests for Hambini hairdresser pics, sorry....)

Of the Chinese open mold manufacturers, I only saw LightCarbon and Longteng.  Velobuild didn’t attend.  (And I didn’t see a presence from other Chinertown favorites like Elitewheels, Ltwoo, Winspace, Magene, etc.)  But I did get to see the LC017 and the LT266 in person, and got some intel on a new LT301 that will be released in a few months:

Just got back from the Taipei Bike Show

You're a hero. Well done and thank you. Alisa is my sales rep at LT. That LT301 looks a LOT like the LT268 that I have, to the point that beyond the frame box, i'm not sure what's different. Weight i guess? Maybe manufacturing process?

The whole "squares are stronger than tubes" sounds wrong. And those boxy tubes look like buses, and buses aren't aerodynamic. Weird. Aero frames always were about tear drop shapes with the tail cut out. Not a box exposed to the wind...

Velobuild is a broker. Light Carbon & Long Teng are factories.

Awesome to learn that LT makes Argon frames, that just upped my bragging rights.

New forum member here, and starting a new thread after posting about this in a thread on the LightCarbon LCR017-D (https://chinertown.com/index.php/topic,4309.255.html).

Long story short: I snuck in to the Taipei Bike Show today to check out some Longteng and LightCarbon frames, and at the Longteng booth, I found out that they have an unreleased frame which is undergoing testing: the RD301-D.  Here is a short video that I took, and a few pages from their brochure with its geometry: https://imgur.com/a/XvH327j.

Appearance wise, the 301 doesn't break any new ground, but a few things stand out:
- It has an aero profile but is under 1000g weight
- The geometry (especially stack) sort of sits between an upright endurance bike and bikes like the Velobuild 177 and 268, Winspace SLC 2.0 and 1500, Yoeleo R11 - this geometry is a sweet spot for me [edit: the geometry seems comparable to the touted all-arounder Trigon AR01]
- Whoa, max tire clearance of 38!
- Cool little storage space on the downtube
- Threaded T47 BB
- Per their rep Alisa, it's made with a mix of T800 and T1000 carbon

This frame hasn't been posted on their website, and Alisa said it will be released "in a few months" once testing is complete.  The 54cm has passed their tests and is available if anyone is interested - you can email Alisa at longtengalisa@163.com.

Peace out!
