I went a few weeks ago. It's an awesome place and I highly recommend it! It was $20 for the 2 hour intro to track riding. The bikes are all new right now and very nice. If I recall, you only need a helmet and no loose clothing. They have pedals for clips or running shoes. It doesn't make you a hipster because the place is the best $20 you will spend in a long time. There were kids going around and when they thought no one was looking they were screaming out loud at how much fun they were having.
I know this makes me a hipster but anyone looking forward to the velodrome in milton opening? I'm thinking about getting a fixie and trying my legs at sprinting. Could be a fun winter hobie. I know nothing about bicycles though and I'm 6'1 so no idea what I need. Maybe they will offer rentals so I can try to see if I like it.
