I hadn’t even heard of RideCX prior to this order. I was searching the interwebs for a product that was difficult to find. RideCX came up as a result of a search. You had one in stock and I immediately submitted my order. From start to finish the process was flawless! RideCX is now in my favorites. Keep up the great work…👍
