You can't go wrong buying boutique kit with proprietary standards from a company with no history and dubious cash flow/backing, especially if it's a knockoff of something you can buy from a global company for less, that looks better (SiSl2 w. Spider-ring).
So when it wears you have to bin the whole spider not just a chainring. Genius.
And is that a proprietary axle interface I see before me?
