Got a brand new bike they were brilliant , 500miles without Any issue , 6 weeks later I get a replacement bike due to a warranty issue on frame , new bike brakes are Garbage need constant fettling and you can’t be sure if they will stop you with the rear brake lever going rock solid and not applying any brake effort to disc after long fast downhill stuff. ! , I would say it’s just your luck if you get a good set or not , if they work there good , if not save up for something better
