I saw this new tantan frameset a few weeks ago: http://www.tantancycling.com/index.php?_m=mod_product&_a=view&p_id=1206

Geometry seems ok, UDH hanger and mono riser.

Does anyone already have experience with this frameset? And how would you rate it compared to the Velobuild TT-023?

 Have you buy it?

Been looking at the same frameset for some time now, but I can't find any info from anyone having tried it.

Looks to be the same as Seraph and Spcycle TT928:

It's also very similar to the Dengfu TT199:

Seems to be hard to mount a BTA system with the monoriser clamp though 

Looks like Colnago

These brands need to quit doing so much with these tt frames. Give us a pretty basic but sleek looking frame with modern TT geometry. Throw in an adjustable front end with a stem/integrated base bar that isn't crap and I'm sure more people would be interested.

I am really curious what aero testing they do in developing the frame? Or they just come up with something that looks cool. That's my major concern with buying one]
