AeroPod, PowerPod and Newton

I have a Garmin mount with Gopro mount underneath. SEE pic. When powerpod is mounted to gopro mount it moves and not firm causing reading issues.

Any suggestions on making sturdier?

[*] Anyone able to mount a Powerpod on the Syncros Hixon mountain bike aero shaped stem integrated handle bar?

Thanks, curious what gear ratio are you using? I will try on my SS, currently 34x20 ratio, using long 185mm cranks for extra torque, it's also a 29er and currently have it set as rigidfork, weight is 18.5 lbs.

Thanks. I ended up using an old tire tube. Cut 1 inch wide and wrapped a couple feet and installed the mount kn it. It seems secure and tight. Glad I put my plate on today rather than tomorrow at the venue.

Got a long distance mtb race tomorrow, race number plate covers the powerpod..if I move PP mount to right/left bar is too narrow to clamp, I guess I could wrap duct tape/old intertube or something). Any suggestions?
