I am an avid mountain biker. I know when a sales person doesn't know what they're talking about. I had been using the same helmet for about eight years and it was time for a replacement. Turns out the tech has changed quite a bit. I checked out some product reviews on YouTube which lead me to All Sport. Once I got there, I used the chat function to talk to a customer service rep. These guys really know their stuff. I was able to tell them what my needs were, what kind of riding I like to do and they were able to recommend more than five different helmets for me. On top of all of that, they had free shipping, which only took two days to get to me, and the helmet is working out great. Bottom line: Tons of great brands and products, knowledgable reps and fast shipping.
