ENSURE YOUR FORK IS COMPATIBLE -VERY IMPORTANT
Incompatible forks: Giant Overdrive 2 Forks. Cannondale Lefty Forks. Carbon Steerers
STEERER TUBE INNER DIAMETER
The inner diameter of your steerer tube must be at least 24.1mm. OneUp is not currently aware of any tapered steerer tubes that do not meet this requirement. If fitting unsure, you can check this by inserting the tip of the EDC Lite into the steerer tube above the star nut BEFORE lowering the star nut position.
STEERER TUBE LENGTH
Most forks are compatible, except for a small number of forks with very short steerer tubes. For the following cases your fork steerer tube length must meet the minimum length requirement.
Measure from the underside of your fork crown to the top of your spacer stack, or top of your stem if you are not running any spacers above your stem.
