I bought two 12spd ones earlier in in the year. A gold bling, super light one like the op’s for my trail bike, and a cheap and cheerful heavy black one on a red anodised carrier for the ebike (because it eats drivetrains).
Both ztto
Anyway, gold one hasn’t had that much use (maybe a few 100 miles) but shifting is very good. Maybe not quite SRAM or shimano, but very good still.
No signs of wear.
The cheap ebike one has had some proper hammer. I’d guess 1000 miles. Wear rate seemed good. However I broke it this week. The small series of pins holding the small cogs to the larger ones have given way, so the smallest three sprockets simply spin around the freehub.
It may have been partially my fault for not tightening it up properly. A couple of times it started creaking due to the lockring coming loose, which I think would have put additional pressure on the pins which are only very small.
Anyway, that’s slightly disappointing, but given the amount of hammer it’s had on an ebike, the price, and that it may be my fault, I’m still happy and have just ordered another to replace it.
Oh, shifting on the cheapo one isn’t as good. But it’s ok / acceptable.
