I asked Justin and he said they used latex and bladder moulds. Is this the same as EPS?

Can we agree that we changed the carbon layup since the first post? It is now T800/1100 and MJ40 end. And they lowered the weight by 100gs. Size 51 is now 780g. If this is true I think it makes the frame quite a bit more interesting. I wish they did EPS moulding.
I think it has been this way quite a while ago. My 54 with stock furniture and coating is 916 g, ordered in December.

Considering how clear the frame is from the inside it should be EPS.

The EPs former id dipped in latex.  The EPs/latex form is wrapped with CF. That latex is the bladder which is the inflated.   
Older methods used bladders made of other materials and without a former.  I.e. both use gas pressure to consolidate the plys

Its hard to read and understand but its accurate explanation.

I finished my build.

Quality is amazing, i didnt find any suprises.

Three things to look after:
- Shimano pressfit BB went almost without resistance
- One bolt seat clamp is shit (used on offset seatpost) it slipped after few potholes.
- Once i pushed seatpost into frame it was battle to raise the saddle (too tight HT propably)

I very like look and overall handling of the bike - i would buy it once again

Size is 510. Wheels are 60mm with 24mm internal on DT350 hubs with Sapim CX and brass nipples from Justin.

I know weight weenies despise white frames because they're usually the heaviest. But man they do look fantastic. I gotta get me a white bike.

Domin. What did you build up with? Does it feel stiff and fast and what weight have you hit?

did you put Loctite on seatclamp bolts? And of course, how is the ride feel compared to your previous bike? I am close to buying either this or LCR017D.

I'd get the 55D over the 17D all day, every day.

I'm leaning towards 55D because the geometry seems to fit me and I like the design. 17D's geometry is so confusing and I don't quite like the down tube design. Only thing that making me think twice is that 55D is more expensive than the other one

I own the Speeder and it is amazing. I only sell it to buy a Time Trial frame but I really recommand the SC-R55D.

I ended building with Ultegra Di2 groupset, Pass Stone chainrings, XCADEY spider powermeter and Elilee X310 cranks.

To be honest, i cant feel any difference between that and Bianchi. I switched to 165mm cranks from 170mm and to 30mm tires from 28mm - it feels very smooth, easy and comfortable to ride. I also think that this setup is quicker, but i need to calibrate XCADEY with Kickr trainer first.

I bought crankset because of the look and i cant find any advantages more than that. Cranks are so massive that i hit my ankle twice on sunday. Chainrings are more noisy than 105 Di2 from my previous bike.

I would definitely choose Speeder over LCR (design, geometry).

Looks awesome.  What did the frame/fork weigh?

Which size do you want ?

LMU

I'm planning my first build, and the first frameset I considered was LTK268-D. After reading this topic, I'm having second thoughts. Is 268 dated compared to this frame?

I don't mind the price difference between the two, and according to this thread QC is great.
