Looking for a little help sizing a GR300 for a 5'9 rider /w 30-30.5 inseam. I have a 52cm Trek Madone 4 series that fits perfect that I would like to get close to on the GR300. Chart below also has two other gravel bike I own / owned that I felt were one size too large.

I may just be overthinking this since Lynskey recommends a medium or medium/large, but the numbers say I need a small.

Weird that someone your height with a long upper body would use a 52. Does it work because you want a low stack and a long stem makes up for the short TT?

I think it's because the Trek H2 geometry runs a little big, their 52 is more like a 53 or 54 for most bikes.

After consulting with Lynskey I think I will go with the medium, was just being over-analytical probably after having a few bikes I felt were a touch too big.
