Reviving an old Classic

Jiggies Cafe in Idaho Springs had been a landmark business for years. So when it closed, we jumped at the chance to take over the historic building and make it our own. From its unique place right on the river to the old-school bar & bar stools, the cafe has provided an amazing space for bikes.

Stop by and see us on your way to the bike parks.

RACING IS OUR BACKGROUND

Our vast knowledge of suspension mountain bikes and components comes from our racing experience, which provides the best testing grounds for the products that we stock, sell, and recommend. When you spend your money with aCOS-G, you can expect fast, knowledgeable service on quality products, and know that the money you spend is going to support and grow the culture of riding and racing mountain bikes. aCOS-G only stocks products that we ride or race. Our history of product testing has created very close relationships with product manufacturers and their employees, allowing our customers to get priority treatment in service. If you are looking for an item that is not in our shop, we will be happy to order it for you. Give us a call or send us an e-mail. We will let you know if it’s something we can order and how long it will take to arrive.
