Argonne Cycle is a great shop with a really local feeling to it… I have gotten service on many of my bikes and bought bikes from him. I met the owner when I was in high school. While going to school Paul would repair bikes for students free of charge, or at an extremely affordable rate. He truly is a benefit to the Millwood community. This shop provides the cheapest repairs for bicycles. I am an avid biker and have gone to almost all local bike shops. This shop used to sell KHS bikes, they are wonderful bicycles, and he is one of the few KHS local dealers. Last time I was at the shop they started caring Jamis Bicycles. The deals are amazing. I bout a $ 1200 rode bike for only $ 750. Argonne Cycle isn’t as cleanest. It is a little confusing to find things sometimes. If you ever need anything just ask him to show you were its at. The customer service is Good. Paul is extremely competent, I would recommend Argonne Cycle over other bike shops in this area.
