That would be great Neal. I have an MC21 wheel here that shared the same setup to the MC18 so I had thought they were interchangeable

I have roughly measured the weight diiference on the kitchen scales....the original setup weighs approx 1.5kg and the lighter sprocket with the Tyga carrier weighs approx 750gms. This was a surprise as in hand the original feels a lot heavier. The lightweight alloy spacer kit I forgot to weigh before installing but perhaps another 200grams saved so approx a kilo all up.
