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!
