Please watch and read the following instructions very carefully. The SPEEDi is relatively simple to install, but there are a few factors that are important to get precise.
Please note that if your SPEEDi breaks due to improper installation, we can't refund you, so it's important you follow the instructions correctly. If you don't follow the instructions carefully, you may install the SPEEDi incorrectly or break it. Pay attention particularly to the notes in red below.
There are also some FAQs at the bottom of the page that will help troubleshoot any issues.
- Backing plate
- Remove rear wheel.
- Clean disc and end cap from all contamination.
- Remove center lock nut.
- Remove factory magnet from center lock nut and set aside (somewhere safe).
- Install center lock nut back onto disc.
- Gently press Backing Plate on to the center lock nut, making sure to line up the 6 notches with the disc rivets.
- Place Magnet inside ring gear and engage teeth.
- Take your time during the final install, make sure everything is very clean for a long and prosperous life.
- For silent operation we aim to leave a .1mm gap between the Cover and the Backing Plate.
- Gently press Cover onto the end cap with thumb pressure only, rotating as you go. This is supposed to be a very tight fit, so will take some pressure to get it on. WARNING! Press as close to the center as possible, do not put ANY pressure on the outer edge of the cover OR hit it with any tool, or it will break.
- As the Cover engages the last 2mm, the teeth need to line up so you will need to rotate the Cover slightly to allow easy engagement. Using a socket that fits over the axle and gently pressing it with your palm is a good way to install easily, be careful not to press it on too hard though.
- Continue to press the Cover closer until you see a very small gap of around .1mm between the Backing Plate and Cover. You can test how close it is by pushing the outer edge of the Cover toward the Backing Plate and seeing how much it moves.
- Rotate the axle to make sure it spins freely and perfectly straight. Try pressing the hub end cap toward the hub and rotating, listening for excessive noise, as the wheel bearings may have play in them that can affect the offset when the axle is done up tight.
- There may be some slight plastic on plastic noise as the sealing faces gently touch each other, make sure this noise is not excessive, if anything sounds or feels off, pry it off slightly (see uninstallation below) and re-install
- Install wheel gently, careful not to impact the unit
- Please note that for the first 5 minutes of use the unit may make some groovy noise, this is normal and will run smooth and silently after its initial bedding in. If it continues to make excess noise, try uninstalling (see below) and reinstalling following Step 9 closely.
- Uninstallation is done by gently prying the complete unit off the hub from the back of the Backing Plate using the three notches.
- IMPORTANT: Make sure to take the complete unit off as ONE (see video). Trying to pry just the Cover off may cause it to break.
Reminder: To avoid any warranty issues, if you need to take your bike into the shop for any reason we recommend removing the unit and reinstalling the factory magnet.
