Welcome to Chain Reaction.

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.

We are a group of passionate cyclists and skilled individuals. Professional, energetic and engaged in the community, we're happy to share our bike passion with the people of Canterbury. Independently owned, we've been selling and servicing bikes and gear since 2000.
