| [title] Determine your spoke length | |
| [* black] To do this, you will need to determine the ERD ([link|https://www.sheldonbrown.com/gloss_e-f.html#erd|effective rim diameter|new_window=true]) of your rim. From what I can tell, Vanmoof uses custom rims meaning this measurement needs to be taken manually. I used a few different methods to measure it and then averaged my results. | |
| [* black] [link|https://www.parktool.com/en-us/blog/calvins-corner/measuring-effective-rim-diameter|This|new_window=true] park tool article gives one way of measuring ERD and [link|https://www.sheldonbrown.com/spoke-length.html|this Sheldon Brown article|new_window=true]gives 2 more ways. | |
| - | [* black] If you have an S2, the ERD that I got was 598mm but my spokes ended up being on the shorter side so whatever you use should probably be slightly larger than that. |
| + | [* black] You will also need the dimensions of your hub. You can typically find these in the technical manual. I found the technical manual by googling around. If you are using an enviolo hub [link|https://enviolo.com/wp-content/uploads/Technical-Manual-enviolo-CY2022-May-2022.pdf|this|new_window=true] is the manual for all of their hubs |
| + | [* black] The last thing you will need is what cross pattern is appropriate for your hub given the rim size. For the enviolo hub it is 2 cross. I found this in the hub's manual as well. |
| + | [* black] After you have your ERD you can enter it into [link|https://www.prowheelbuilder.com/spokelengthcalculator|this|new_window=true] website along with the dimensions of your hub and the cross pattern you intend to use. It will calculate what length spokes you need. |
| + | [* icon_note] If you have an S2, the ERD that I got was 598mm but my spokes ended up being on the shorter side so whatever you use should probably be slightly larger than that. |
| + | [* icon_note] If you have an S2 and are using the exact same hub as me, the spoke length I used was 254mm. Again though my spokes were slightly short so I would add 1-2mm to this length. |
