I emailed LightCarbon for info about a wheelset and also asked about the LCR020.
They replied that "All 7 sizes should be ready by the end of the year". They confirmed 1100g for the 54cm frame.
The price should be around 799$ including fork, seatpost and HBR17 handlebar.
So we are basically looking at half the price of XMCS and less than half the price of QuickPro or Tavelo.
Most of that price difference (I suppose) is given by the fact that it is a standard frame construction rather than a monocoque construction (XMCS). Another big difference I suppose is in the amount of high modulus fiber (that is the reason for the higher weight) and in the refinement of the layup (again another reason for higher weight). In terms of stiffness and riding quality, actually, the frame might be relatively close to the other ones (XMCS, QuickPro, ...) since more weight implies more material, therefore a thicker lower modulus carbon fiber frame might end up really similar in stiffness to a high modulus frame with thinner walls for weight reduction.
This kind of approach, as far as I remember, is the same chosen from Merida for the latest Reacto. CF3 is lower modulus, CF5 is the high modulus frame...but the CF3 layup was engineered to give the same stiffness and ride quality of CF5 (at a higher weight). Interestingly, Merida claims about 1185g for the Reacto CF3 frame (which is quite close to LCR020 declared weight).
I am really looking forward to buy my first aero bike (currently riding titanium) and I cannot decide what to do. The Merida Reacto here in Europe can be bought for about 2800-2900€ (I am referring to 105 Di2 setup and alloy wheels, to be replaced with wheels from some chinese brand), QuickPro/Tavelo/XMCS are relatively expensive (frameset + groupset is very close to Reacto's cost) and the LCR020 will still take some time to reach the market...
