Might there be anyone here who can make sense of this geometry chart? Bewilderingly, some of the main measurements are missing. In another picture of this chart, they actually highlight in red the standover, the reach and the stack - and label those lines in red too - but then fail to actually give you the numbers.

Is anyone more skilled than I that can give the stack, reach, BB drop (I think this is HAV), BB height, headtube angle (might be "Sloping"?), trail, rake and wheelbase?

If so - thanks! I can tell it's fairly lively - which is what I want - but I wish to compare it to a current bike.

Thanks so much!

Would love to know stack and wheelbase if anyone can figure it out. I dunno, feels like it shouldn't be a puzzle. Not sure why they didn't include it. Cheers!

I've got calculated XY values for the Look 586 in the frame comparison (free) tool on velogicift.com
Look hadn't caught on to reach and stack at that point.
