What our customers are saying:

"I've had nothing but great service from everyone at Pegasus. I have made multiple orders and they have come super quick. I haven't had a question go unanswered anytime I have called. The Pegasus team is definitely a knowledgeable and well liked company. For anything racing Pegasus is my first choice. Not once in my life have I entered a new sport/hobby and had all of the equipment this easy to obtain. From staying past closing time to help me get geared up, and all the simple questions I have on the phone, Pegasus is always the reliable source I go to when I need anything racing."
