    Replacement derailer rocks

    My experience using the component is delightful! It is smooth as silk. My experience with bikesonline is strange and wonderful. I bought the Siskiu T8 and the derailleur broke almost immediately. Because I didn’t see how I caused the break, I requested an upgrade to this XT model and bikesonline graciously granted it, without blinking. They didn’t have to do that. I consider that response above and beyond normal responsibility. I think it was exemplary dedication to customer service for sure. In doing so, they acknowledged the inconvenience and disappointment the unfortunate event caused me, and did what they could to make me feel better. It worked!
