|   Correct way to measure stem length | AK47
Dec 14, 2002 4:51 PM | | What is the correct way to measure stem length? Is it from the center of the headset to the end of the stem? Just need some help as I want to upgrade the stem on my current bike and want to get the same length that I currently have. Thanks! |

Not absolute, but ballpark. For instance, look how the reach of a 90mm x 6° stem and 105mm x 25° stem are relatively similar, while the rise increases dramatically.
