If you are in Grand Junction, or GJ as we like to say for short, stop in to Ruby Canyon Cycles. Located in the beautiful downtown historic district (map), the shop has all you need for your biking adventures. The staff is very knowledgeable and friendly, and can recommend some rides to check out in the area. If you are looking to upgrade, need a whole new ride, or just need to get something fixed, these guys know their stuff - without the condescending attitude that many bike shops exude. Fair prices and quality stuff, including state of the art chain management solutions from Grand Junction based company MRP, and yes - you might find some StemCAPtains there too. .
