Hi David,
I just sold my Wisper 905se being concern about the quality who can cause me problems in the future. (I think is a good news for you to lose a complainer).
You are extremely lucky to have people like Claudiu in your company. This person has one of the best Customer service skills who I have met in the last years here in UK.
You have good Customer service, but the closer dealer for me was 10 miles away.
About the brakes...Was made the same noise like in the first days of use when I was to made the service at 500 miles.
I received the different disks, better quality and my bike was 100% a different bicycle. But was not like this when I paid the money for this product...
If I will buy a Wisper again?
What do you think David?
All the best!
