Hi everyone,

I’m looking for some geometry advice on the LightCarbon LCR018 frameset as I have quite extreme body proportions and I’m struggling to pick the right size and stem length for my build. My current bike is a size 61, which was a result of some bad advice from a friend, and it's definitely way too big for me.

My height is 182 cm with a 92 cm inseam, which means I have very long legs relative to my height. I am also recovering from ACL surgery, so I need a stable setup that is not too punishing on the knee while remaining fast.

Looking at the geometry chart for the LCR018-D, size 540 has a reach of 383 mm and a stack of 569 mm, whereas size 560 offers a reach of 389 mm and a stack of 586.8 mm. My main concern is that with a 92 cm inseam, my saddle height will be very high and on a size 540, the saddle-to-handlebar drop would be massive. I am leaning towards the size 560 to benefit from the extra 17.8 mm of stack height, but I am worried about the 389 mm reach being too long for my relatively short torso.

I am considering using a shorter stem, perhaps 90 mm or 100 mm from the available options, to compensate for the longer reach on the 560 frame and I wonder if anyone with similar 'all legs' proportions has experience with a shorter stem on this specific integrated cockpit.

Given that the LCR018 has a fully integrated cable routing system and a specific cockpit setup, would you suggest doing a professional bike fit before ordering the frame and handlebar, or is this geometry standard enough to adjust later? If anyone with a 90+ cm inseam has built this frame, I would love to hear what size and stem length you chose to avoid feeling too stretched out while keeping the front end high enough.

Thanks!

Wendy offers me c53db for 479$ + 120$ shipment to PL. Its not possibile to ship it together with the frame in one package.
Have you received your wheels already? If so, any thoughts?

I'm now wondering about the large stack of spacers.

Before deciding on the LCR018D, I had a bike sizing session. I was convinced that size 56 would be the right choice, but the fitter said my position would be too aggressive because I'm 182.5 cm tall with a 92.5 cm inseam (yes, I know that's a pretty unusual combination).

He recommended going with size 58 and an 80 mm stem. My concern is that such a short stem might make the steering feel too quick and also leaves me with very little room for future adjustments.

Do you think a size 56 with a 90 mm stem and 40-50 mm of spacers is a viable setup? Has anyone here actually ridden the LCR018D with that many spacers and if so, how does it affect the handling and front-end stiffness in real-world riding?
