Well that was interesting. Sitting around watching the tdf and browsing the forum, so I decided to try this spreadsheet to see how it compares to my fit that I've settled on over a few years of trial and error.
86cm inseam, 50cm arm-finger, 8-9 flexibility, 45 shoe, not many variables here are there?
Suggested top tube = 56.5cm
current best fitting frame = 56.5cm
Suggested saddle height = 76.5cm
Actual saddle height crank center - sit bone contact point = 76.5cm (really)
Suggested setback = 8.4cm
Actual setback = 8-9cm range
Suggested stem length for 56.5tt = 115mm
Actual stem length for 56.5tt = 120mm
Suggested drop = 8cm +/- 1cm
Actual drop = 8.5-9cm
Suggested crank length = 175mm
Actual crank length = 172.5mm
Interesting... I'm not sure how I would feel about 175mm cranks but maybe I should give them another shot one day. Also not sure if I would be on a 19" mountain bike like it says, my friends' 19" 29er is massive and I feel like 17" might be better. Similarly the 130mm mountain bike stem estimation is probably inaccurate for modern 29er geometry based on what I've seen.
Perfect fit. Congrats, and you did it trial and error
. As i know 29er are the same only bigger wheels. Yes your size is a 19. 2.5 mm in crank arm is not so much.
