I can feel your pain, but I have to say that Inline Tube is a vendor that I buy anything I possibly can from. Their customer service is 2nd to none IMO. They helped me out originally by straightening out a brake kit for my Wildcat a long time ago. But recently we bought their rear brake conversion for the Cutlass. They advised before I bought it that one of the brake cables might not fit correctly. They were correct and asked me what I need in terms of cable length and sheath length and over nighted me exactly what I needed and it was spot on. And for no charge of any nature.
I've purchased from them 4 or 5 times without issue.
Have you contacted them?
Thats good.
Everytime I get something from them its always slightly off
