Step 3
Stretch your frame dropouts
- You need to stretch the rear frame dropouts because the 8 speed hub is wider than then 3 speed one
- I got my local bike shop to do this because there’s a risk for damaging your frame.
- The cost was $150 AUD

Step 4
Replace the spokes
- Remove all the old spokes from your wheel
- Spoke the 8 speed gear into the wheel. This is the best guide https://www.youtube.com/watch?v=mIU6mi0K…
- Tighten all the spokes using a screwdriver. Use the same torque on the screwdriver and check by “plucking” the spokes so the sound the same
- Turn the bike upside down, install the wheel, and true the wheel. I hold a screw driver against the frame and slowly spin the wheel. When it move in, I just tighten the opposite spokes
