How To Measure Stem Length?
 

As the title suggests... do you measure from the centre point of the steerer hole to the centre point of the bar hole, or some other method. I'm trying to determine what length of stem my bike came with to help me decide what size to get for an upgrade.

Thanks,
Kris

I've always found this webpage to be immensely useful in these situations...
