dear knock-off wheel friends,

I tried the new TRIGO stud bolts on a spare rotor lying in my garage.
the fit perfectly. the wheels are a bit more forgiving than the centering ring. they slip right on. the ring is a bit tight.

the new version of stud-bolts is black with an internal 12-point M12 hex.
a 12mm Allen socket will be needed.

I got two sets so I feel that they are widely available now.

enjoy,
