Another track sizing question

[Pb]

Hey guys,

Im looking to get a track frame - the geometry charts are below. I have had a retul bike fit for my road bike - giant propel and thinking it should match quite closely to the track. Looks like I fit between a M and L and leaning towards a L. Can anyone give me some advice? cheers

Hi Pb
My son rides a 56 road bike and a 56 track bike (Koga). His fit is perfect on both and people always comment about it.
Hi measurements are 770 saddle height compared to your 758.
Handlebar reach he is 580 compared to your 538.
You are more like my size which is a 55, rather than my son who is 56.
So I would get the medium (550 / 558)
Track bikes you should always err on the small size rather than too big.
58 is too big for you.
