stirlingpowers Posted September 1 Report Share Posted September 1 (edited) Effective stack = vertical distance hands to feet, or in other words: bar end height - BB height I get values of 680 to 750 mm filling in the manufacturers' missing values, but that's a bit vague. https://madscientistmtb.com/bike-geometry-compare/ says approximately 735 mm for a Hex Team. Unfortunately, I can't get my hands on a bike where I live. Thanks in advance, and I will post several cat pictures as compensation.

ben_travis Posted September 5 Report Share Posted September 5 (edited) Surely ‘effective stack’ is meaningless to compare bikes as so many factors can change the measurement (bar geo, stem geometry, stacker quantity / height, fork length, and lots of others that could technically change it). I could get a fourplay to have a similar effective stack as a raleigh burner if I put the correct components on it 🤷🏻♂️ This is why stack is taken from centre top of head tube, as less factors have an impact edit: to be slightly helpful, I will try and get you my bar height at somepoint Edited September 5 by ben_travis Quote Link to comment Share on other sites More sharing options...
stirlingpowers Posted September 5 Author Report Share Posted September 5 (edited) All true, but I want to decide on the stem for a given frame and fork. It feels too low for me now, but I don't know much about street riding, I'd rather learn with the tried & tested geometry. If you measure, could you tell me whether it's the Hex of https://youtu.be/watch?v=JouWWKuBNbw? That would help nailing down the stack to a centimeter.

ben_travis Posted September 14 Report Share Posted September 14 Sorry for the delay, to confirm, to top of grip my bar height is 107cm, and yes, it is the hex in that video Hopefully it helps you out. 1 Quote Link to comment Share on other sites More sharing options...
stirlingpowers Posted September 15 Author Report Share Posted September 15 That helps, a lot. THANK YOU! So your effective stack should be slightly above 710 mm. With this abomination https://www.ergotec.de/en/products/vorbauten/sub/ahead-vorbau/produkt/high-charisma-31-8.html, I have 720 mm, but I can lower to 710. Feels a lot better than the 680 I previously had. Quote Link to comment Share on other sites More sharing options...
