OneUp Components EDC Top Cap- Stems

   Fork Requirements–        The EDC Top Cap Kit is only compatible with 1.5″ Tapered mountain bike forks with an aluminum steerer tube. Carbon and Steel steerer tube forks are NOT compatible.To install EDC in your fork you must have at least 3mm of steerer tube above your stem when installed and use a minimum 5mm headset spacer above your stem. A 10mm headset spacer stack above your stem is recommended.

   Steerer Tube Star Nut Diameter–        The inner diameter must be between 24.25 mm-24.80 mm. To check, this will require a OneUp “Go, No-Go Gauge” or a good set of calipers (that your local shop should have). If you have a Fox 32 we recommend checking this before ordering the tap and gauge kit as some models have steerers that are outside this range. Otherwise it is very unlikely you will have an issue.

   Steerer Tube Minimum Diameter–        Minimum diameter 22.1 mm (0.87″). To check, you can push a 16g or 20g CO2 cannister or a standard MTB handlebar up through the hole in the bottom of your fork steerer. If you can touch your star nut, you’re all good.  

   Steerer tube Max Diameter (opening in the underside of your fork crown)–        31.75 mm – 34.00 mm dia. (1.25-1.34″). This is to ensure the EDC fork plug can be fitted. This is not essential, but ensures the EDC tool cannot rattle inside your fork.
