I've seen this frame in other aliexpress listings, as weighing 850 grams (same weight and geometry given by the Tomasso website for the ZONCOLAN SL CARBON ROAD BIKE). However, these particular listings give 765g. Maybe they are doing a better job of laying the fiber? It sure doesn't look high tech, with its right angle at the rear of the bottom bracket. But 765g is still lighter than the Hongfu FM008 (820g), or the FM066. Has anyone built one of these 765g frames, and are they really that light?

Here is an 850g version:

It looks the same as Longteng LTK-118 (aka Velobuild R077, Ribble SL, … etc.), of which I've got one 56cm weighing in at 853g (with derailleur hanger and cable port fittings). Maybe they're quoting the weight of smallest frames? 765g(raw, no hardware, no BB sleeve, no clearcoat… we know the caveats :roll: ) for 47cm frame seems plausible.

Yeah I got an LTK118 and I got 860g frame weight in a size 54, including hanger and cable port fittings too. 765 is definately possible in smallest size with no hardware whatsoever.

These frames are plenty light, if not the lightest in the world. But so far i've put a little over 500km on mine and I'm IN LOVE with the thing.
