Answered Shockwiz compression ratio

[Haribo20]

HI,
I have a 2020 Cube Stereo Hybrid 160 with Fox 36 ebike fork (170travel). If i remove or add any volume spacers, will this change the compression ratio ? I find it hard doing the shockwiz calibration so it would be useful to just enter my previous ratio and not go through the entire setup/calibration.

Many thanks
HB

I share your pain when it comes to establishing the compression ratio. Best done with a heavier friend to assist (while you monitor the progress and tell him to press harder, again!)

When you think about it, the whole point of adding a volume spacer or two is to reduce the volume of air that gets compressed. Therefore it MUST alter the compression ratio. It must alter it by a noticeable amount or it would not have an effect on your fork's performance. So therefore adding spacer(s) will alter the compression ratio. Adding spacers will reduce the ratio.

Thats how how thought it would be, just hoping for the easy option. I struggle with both the compressing and extension. If i wanted a proper work out I wouldnt of got an ebike ??

You are allowed to let some air out of the fork you know!

It is still hard work, but it is a LOT easier.

Lett too much out though and it doesn't work!

You have to remove air pressure for calibration. Follow the instructions from the Calibration Wizard.
