When I first decided to build a track bike my friend Gianna Blanco told me about your pro track frames. I did some research and in no time at all ordered by far the best frame ever, kerin pro track duo chrome. This frame is durable and super light weight. I will be purchasing more of ur products in the future. Btw my friend that sold me on ur products also sent in her resume for a social media position. She is super motivated and has an extreme passion for the bicycle scene. In closing thanks to ur customer service for answering all my questions and to everybody else you guys rock. Patrick Corcoran
