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!
I'm 183 with 89cm inseam. So also long legs but a bit less extreme as you.
Ive chosen the 54 with 120mm stem and it's ok for me. Maybe a bit short. Ive got the bar completely slammed and don't feel the saddle to handlebar drop is aggressive at all.
I'm thinking that I could also make the 56 fit me well (maybe better) by choosing a non riser bar and 110mm stem.
That being said, I'm quite flexible and adaptable. I also have no clue what your riding style is and how flexible you are.
So bottom line, how I fit on the bike, with kind of similar proportions, is hard to compare because we could be comparing apples to oranges. A bikefit is always a good idea if you're unsure and don't have a decent baseline to go off.
