Morning Errol, I again apologize for the experience that you had in the store, and yes we should have acted in a way more professional manner! I can assure you that we learn from our mistakes and continue to try and improve service across the board. And value any feedback from our customers. After fitting the new wheel set and new brakes free of charge I am very disappointed to hear that there is an issue with the rear brake. This brake was brand new so this is definitely a manufacturing issue. But again I will be pleased to be given the opportunity to rectify this for you and ensure that the bike is 100% Thanks for your time. Kind Regards, Duane Stander
