Any tips for home made riser systems to elevate the Polar Power sensor (I think it’s also referred to as the surfboard) from the Chainstay to the required <30mm distance from the chain? I’ve seen a few funky examples on line, but can’t ascertain what people used in the construction.
Also, I heard the new polar power has a new ingenious riser system that will address the shortcomings of the current system. Has anyone seen this system?
