Please do share as I am surprised that the 52 would work for a 177cm tall rider - but I have never been one to fully understand the geometry measurement tables for any bikes and how they would apply to me.

Hey all,
I’m following this awesome thread for a while and I’m now also in the process of ordering the new LCR018-D and can’t decide between size 52 or 54.

My details:
– Height: 176 cm
– Inseam: 82.5 cm (measured in underwear using book method)
– Flexibility: not great
– Riding: mostly endurance longer rides, occasionally on flats in aero position

I don’t have a comparable modern bike – my old Bulls was a 56, but it felt too big and isn’t a real reference point geometry-wise.

What I’m considering right now:
   •   Size 52 → 100 mm stem, 15 mm seatpost offset
   •   Size 54 → 90 mm stem (or possibly 80 mm), 15 mm offset

LightCarbon told me both sizes could work — it’s mostly preference. So now I’m trying to make a well-informed decision before placing the order.

From reading through this thread, here’s what I noted from other users around my size:
   •   177 cm / 82 inseam → chose 52 with 380/110 and 0 offset
   •   178 cm / 83 inseam → chose 54 with 380/100
   •   177 cm / 82 inseam → said they’d go 54 with 90 or 80 stem
   •   178 / 87 inseam → going for 52 with 110 stem

If you’re around 174–178 cm, I’d be super interested in hearing what you went for — or would go for — and why.

Also curious to hear from anyone riding a similar endurance-style geometry.

Headset bearings for anyone interested are MH-P16.
  are the headset bearings included in the frame? Or you had to buy them?

I bought the one supply by LC and I torqued it at 30 N.m (recommandation between 25-35 N.m) without any problem. I used those tools. It helps to avoid scratching the BB or the frame :

Can someone who has already received their LCR018-D frameset tell me about the thru-axels? Any good? I've already got my farme on order and was wondering if the thu-axels were okay or worth upgrading. What are the exact dimensions as I'm guessing with the front forks having a 'blind' thread the exact length is critical.
