Chain Reaction Cycles

Chain Reaction Cycles is proud to support MountainBikeNI.com

Established in 1984, Chain Reaction Cycles (CRC) has grown to become the world’s largest online bike store. Still based in Northern Ireland, we've supported grass roots mountain biking and the development of new facilities since day one.

Our two stores in Belfast and Ballyclare continue to serve the local cycling community with a huge product range and unrivalled expertise. With over 90,000 products in stock we stay true to our core values of selling quality products at the best possible price and always being on the end of the phone or email when you need us. There's always a happy-to-help friendly face in our stores too.

Everyone in CRC is excited at the recent off-road developments, so we look forward to seeing you on a trail very soon!
