• Replacing the sprocket on an IGH is straightforward, although things can ping off around the workshop. It can be done at home as long as you have basic tools and follow some instructions. As long as the cable outer is long enough to still reach the first cable stop on the frame and not be put under tension when the bars are turned all the way to the left and right, then changing bars is not an issue.

  • If you clamp something like molegrips/a cable tie/ a clothes peg on the axle it stops the spring retaining ring pinging off around the workshop when you remove it.
