Oh shit, they are out now??
What resistance mech did they use?
We got them about 10 days ago.
They use a totally different resistance mech and gap adjustment.
A 2 piece keyed washed sits inside the keyed clutch. The inner part has a flat in it to keep it aligned with the axle, the outer part keys into the slots of the clutch. A spring creates the resistance between the 2 parts as outer section spins around the inner section (if that makes any sense)
Here are the 2 parts of of the helical adjustment spacers.

As far as any concerns to these parts being plastic. There really isn't load to these parts.
