Tires were in stock at a great price, and they shipped super fast! My first time shopping here, but communication was great and the tires arrived fast and with excellent packaging! Tires themselves are super fast and exactly as expected. Thanks!
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…👍
