Hi Chuk,
Yes I saw your post. I think we need to ask Grip Grip exactly what pulley he sold to Brett. Are you saying that the Karmen 62mm pulley is aluminum and not hardened steel? I don't have mine here right now to check it. IMHO it could be a steel alloy material that might not react to a conventional magnet test?? I will ask Khang Vo. Maybe also someone more knowledgeable about the material used to make the grooved pulley part on the 62mm Karmen pulleys can chime in.
In the meantime also I'm waiting from more definitive information hoping to come directly from Rudy so maybe he can clear that up . . .
