Was trying to fit the new lighter rear alloy sprocket holder that Tyga supply and had a question. As its not threaded like the standard steel Honda one, what are people using as a nut?
Normal nuts seem too deep for the length of the thread on hand (check pic) and I suspect shallow ones may lack the torque required?
Are those cap screws from the mc 18 ? On my 18 carrier they look the same as yours except that they screw into the carrier and on my 21 it is a bolt and nut system .
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.
These are pics of the later MC21 arrangement.....are the threads able to be removed? Or are they a part of the sprocket? Seems limited for choice when racing? Maybe I wont be able to use my lightweight sprocket afterall.

The 21 sprockets need a bigger hole for the bolt to go through . You need to clean out those holes on your sprocket so the nuts don't get jammed .
Neal I have bought a secondhand MC21 sprocket as the nuts I need don't look to be an item you can buy separately. Where did you get your sprocket carrier looks very minimalist.
