The staff was very accommodating!

Excellent experience. My initial conversations were with Tyler. He listened to my goals, took into account age, size etc., then made a few recommendations. As other bikes became available he updated his recommendations, this led to my final purchase…and I love the Orbea Rallin M-Series. I worked with Andy on the actual purchase, he was also very helpful.

Purchased Specialized Allez Sprint Frameset. Found size I was looking for, flawless transaction, and shipping, item received in reasonable time. Overall, very happy with build and ride. I don't think I will be trading this one in. Avid Rider... Would definitely shop at The Pro's Closet again, no question about it.
