Question REG. sprockets adapter

[Jumpa]

Do these type sprockets bolt onto where the rotor goes on the hub?
If so has anyone tried them out?
Tthe holes on my hub seem rather thin to be taking all that force,
then again we've seen smaller bolts take a lot more.
Thanks for any info good or bad!

i believe it threads on ... not 100% sure
your best bet would be to contact seller

that particular seller is part of a new store in Miami. their stuff (for the most part) is top notch quality. and a price tag to match.

Those are sometimes called a "top hat" adaptor because of the shape. It gets sandwiched in between your disc rotor and the wheel, so yes those little disc rotor bolts are what's driving you, and you for sure wouldn't want to cheap out on low quality ones.

is the one pictured above
a quality one ?
