“True” reach calculator 

Did you know your stem hight changes your bikes reach?

This calculator will adjust your reach number based off your stem height. The slacker bikes get, the shorter your reach gets! 

Just Input your frames headtube angle, the reach of your frame, and then measure from the top of your head tube to the middle of your stem (that’s your “Center of stem from headtube”). Put the numbers in the calculator and hit calculate. That’s your true reach.

All lengths in mm.
