As a result, the safety wire constrained the expansion of the wheels to a certain diameter which allowed us to ramp up to around 6000 rpm at Champs for taking shots. As for the process of installing them, the safety wire was wrapped once around the wheel, cut to its length, and then two ends were twisted together and then stuck inside the neoprene so as to prevent it from contacting the boulder. I have attached a picture of the flywheel below.

Round safety wire 0.032" diameter. 1678 ran 2 wraps around our wheels. It's a little bit of a tricky process. You must get the safety wire tight and squeezing into the wheel a little and you will almost definitely break some wires in the process of twisting them. Try until you succeed To stuff the twisted wire end into the wheel use a screwdriver or awl to stab into the rubber right next to the twisted end, then stuff it in.
