Just Google "Tarmac SL8" 

Haha! I actually laughed out 
Okay on that note...I will see my way out.

For anyone trying to sustain a 90-degree elbow “breakaway TT” position over the hoods, you need more stack. This kind of solves that.

Peak Torque speaks on this a lot. Sure you can always use more spacers, but allegedly this will decrease overall stiffness in the front end. Versus running a slammed stem.

The issue is exacerbated with the advent of shorter cranks. Typically you'd need to increase both saddle height and stack height to accommodate the smaller crank diameter and open up the hip angle. So what is originally intended to be an endurance geometry with, say, 172.5mm crank arms quickly becomes an aero geometry with 165mm cranks.

Anyone has a problem with saddle tilt? Sometimes after coming back from out of the saddle, saddle can tilt a bit If I don't land perfectly in the middle.
Is this normal? Any fix?
I'm using carbon rails with 9x9, but it sits really nice, 12nm

Yup me as well. It's why I despise single clamping designs especially if your saddle rails aren't squarely clamped in the middle to evenly distribute weight.

Since I really need a 20mm offset seatpost I had push my saddle all the back to the very limits. This is a recipe for saddle tilt slippage upwards.

I definitely need to do a deep dive research on carbon fiber and educate myself better...

TanTan shows a size 52 matte black weighing 836g. My Tarmac L8 Pro in a size 56 weighs 827g. Now let's say a size 56 TanTan x68 comes in at 900g for comparison sake. How are they able to produce a comparable weight with less fragile (ie: stronger) carbon? And at a $600 price point? Is the difference between a $600 frame versus $3500 all in the marketing, engineering, tooling, staff, and frame size-specific layup?

ICAN's FL1 frame (Aethos lookalike) comes in at 783g unpainted in a size 54. No aero design details so less carbon needed, but obviously the Chinese brands are capable of making lightweight frames. My Winspace SLC3 weighs 829g. I'm just curious why we don't see more of these brands offering deep sub-1000g frames. Most of them seem to fall between 1050g to 1200g.

In the past I've said my theory as to why Chinese frames are heavier is because it's a built-in insurance policy by making the frames, in theory, more robust. But why would they need to do this if an 836g frame is strong enough without cutting corners?

Obviously I like what TanTan is doing by offering such a wide variety of frames across different disciplines. So I'm not trying to scare anyone away from this particular frame. I really want one myself. My curiosity lies in TanTan's ability to offer this frame at such stellar specs and price as a reputable factory. With minimal compromise.

Just a quick update on my order.

D50CU-33 w/new in-house straight through hubs & 5mm width carbon spokes are ready to ship. 

Thanks all for your help and of course to Peter for being so patient and helpful with me as well as for making these wheels available.

Incredible. I went with the same rims and hubs, but different/thinner carbon spokes.

Here’s the gap on my SL8 for reference.

Hot dang! Now that is a gravel build. And extra kudos on the Nova Ride OSPW. Thanks for sharing!

I assume the cassette is a 10-44t?

Any issues with tire side wall cuts on those Goodyears paired with the XPLR Zipp Wheels? I have not heard great things about those tires from both consumers and even Sram employees.
