Picked these up as spares for my Shimano brakes and they fit exactly as listed. The resin compound is quiet and has solid bite for everyday trail riding, and the stainless steel back plate feels durable. Installation with the included spring was straightforward. Only reason for four stars is that resin wears faster in wet, gritty conditions, so keep an eye on pad thickness. Good value if you want reliable stopping without spending much. Works with BR-MT200 and BR-MT400 in my experience.
