Welcome to Chain Reaction.
We all remember the first time we rode a bike, the wind in our hair, the freedom, the joy! At Chain Reaction, we love riding dirt, road and even BMX. We love riding with our family and friends. We offer new and old riders a place to talk with experienced staff who can help you on your cycling journey.
Since Chain Reaction first opened in 2000, we have helped thousands of cyclists achieve their cycling needs and dreams. We support the biking community through events, trail building, rides, seminars and athlete support. Our friendly, helpful staff all ride, from the commuter, the road rider, trail, downhill and BMX. We all have one thing in common, we love bikes and want to help you enjoy them as much as possible.
Call in and meet us, get some advice and maybe take a bike for a spin. We have exceptional gear to offer and want to help you get the most out of your bike.
