Does the job but. . . .
"These adapters come in stealth black and some other black name (which are shiny or matt). Its not clear which is which, why not just say matt or shiny? FFS. It's annoying and a Hayes thing, not Bikeparts. Anyway, having tried to find a 'matt' one to no avail, sprayed this one with some matt acrylic paint I had lying about. Keep it simple Hayes. Bikeparts are awesome, thanks!"
