I want to say a BIG THANK YOU to Charlie North of Trek Bike Turramurra. His customer service is second to none. He is patient, honest as well as helpful in my purchase of a Trek bicycle. I am what you called a problematic customer, riddled with back and knee injuries and my reach and height played a difficult part in size selection. Charles have been so accommodating to my needs. He puts in long hours (after office hour)to calculate the right mixed of measurements for my saddle and handle height plus reach. I subsequently cancelled my order with Giant and bought the Trek bike and i didn't mind the 2 months wait.
