This frame has been in the wild for a while, i got my local LLM to summarize the thread. For those interested, see attached.
Expect mistakes, it's one shot, 200k tokens. I read the whole thing, it feels correct enough.

pi --session 01a0908e-76fb-7730-abbd-b2911fbf1a52

generally reads pretty correct!

*aero*, *high-stack*, and *40–41 mm* tire clearance - quite the ask for your client!

Long Term Long Teng update:

Currently at 4,970KM, will surpass 5000KM after a short afternoon spin tomorrow.

No problems at all with the bike since I built it up. I love it.

A few things I have changed:

Swapped to an ENVE Selle Italia Boost SLR 130, which fits me better and which, when slammed forward, is helping me rotate into and sustain the aero hoods position.
Swapped the 35mm Michelin Pro5 (37mm WAM) tires for 32mm Continental GP5000 S TR (33mm WAM). The fat tires were comfy and fast, but I am happy to drop the weight ~150g, and I think the GPs fit the bike better without much compromise. I am back on shit roads in New England, though, so I don't think I can afford to go skinnier. I think, despite the generous tire clearance, that the bike probably fits 30mm tires best--is designed around 28-30mm. I was getting toe overlap on the 35mm Michelins, and I think for big tires a slightly larger BB drop would be welcome.

I just got 165 cranks but haven't put them on yet. I'm on 170 currently but want to keep optimizing the trendy progressive fit and also open up the hip a bit as I'm dealing with some chronic hip mobility issues on one side from an old hip flexor injury on the squash court some 8 years ago 

Attaching a picture of the current setup.

Thanks for your detailed feedback, Stephen — this is actually where I first came across it.

I guess this is exactly the value of real-world testing by end riders. Even though we do lab tests — impact tests, fatigue testing, stiffness measurements — how a wheel actually feels on the road is just as important. Plus, real riding often surfaces issues we missed, or new ones we hadn't considered.

Before we deliver the final products, all of this feedback helps make them more reliable. Either way, we'll always stand behind our products and take responsibility when something goes wrong.

the ai slop is not helping convince me to buy your products

Just resist the urge to send this sh*t, please. respect us.

Great job with this, although I think some specifications have some typos, like the gravel and sl steel's inner widths.

Just echoing this, here's a screenshot from the steel page.

Hi, I am building up my frame and everything went pretty smoothly so far. Only thing I am not completely understanding yet, did everyone in this sub need to cut their steerer tube? I’ve got a FSA acr no55 LS headset, 40mm of spacers, and a 35mm high stem, and there is still like 25mm of steerer tube coming out of my XXL frame. I was assuming upfront that I wouldn’t need to cut my steerer, because it was an XXL frame and I have pretty high stack. Did everyone in this sub cut their steerer? I am wondering if I am doing something wrong as it’s my first bike build.

Yeah everyone cut their steerer. Personally, i did it twice -- once by a friend who has built scores of bikes, and then a second time by my local mechanic once I was sure i wanted it fully slammed.

Ordered a Large, in "transparent blue" may 23.
Shipped about a week later, and recieved it yesterday, so just over 2 weeks.
Built up today with a mix ultegra/dura ace, ztto 11-34, x260 crank, DFS 60/60mm wheels and pirelli SL-R 30mm, (heavy) 130mm enve aero stem and enve aero 37/42 handlebar.
Weight is about 6.7kg as shown inc pedals, aero bottle cages, computer mount.

Build was quite straight forward. No issues, but I might have to flatten the brake mounts, because brakes was screaming when I tested it in the yard.
Taking it for a ride tonight.

Best color so far... Kinda jealous!

If you're getting the LTK266-D-SL and moving a SRAM Red groupset onto the bike, you really don't need to weight weenie as hard with the handlebars or the wheels if you goal is just sub 7. Different if you want sub 6.8 or 6.5. For the handlebars anything under 350g, really -- which means you won't have to sacrifice stiffness. Same for wheels, you can get cx-ray steel spokes and moderate depth-- shoot for anything under 1300g. Especially if you plan to run standard 28-32mm race tires.

Here's a shot of I don't think I have shared yet, from last fall, of the LTK266-D-SL with Tavelo Avro bars (130mm stem, 380mm width bars at the hoods). This is with FSA no 55 and the comparible spacers from Tavelo (via Panda Podium). It is slammed.
