Hi does anyone know the measurement of the red highlighted dimension of a stem? Just look for a general measurement- but wouldn’t mind specific la for an FSA gravel stem or the redshift suspension stem. Thanks!

They all vary. Why do you need this?
I don’t think it’s a common thing most manufacturers list. It also doesn’t matter at all unless you cut your steerer too short.
It’s 40mm on the Redshift. Generally for any stem you can assume it’s 40mm. I have about 20 stems and only one isn’t 40, and that’s actually thinner at about 35mm stack height.
The redshift one is listed on their website under technical specifications. Steerer Tube Clamp Stack Height Depends on the size
They all vary by slight amounts. It is not really a big deal though.
If you get a new stem and its stack height is lower than the one it is replacing you might have trouble preloading the headset. You’ll just need a longer spacer or maybe an extra 2-5mm spacer to pick up the difference. Sometimes the LBS will just give you one free if you’re in this situation.
I have that same redshift stem. Just measured it and it’s 40 mm
measure pressed against the bone, all the way to the tip
It’s not a standard height.
Most are around 40mm tall though.
