Brodie is a reputable bike company in Canada. The bike is completly upgradeable. It is about $600 new, and I got it at a good deal. Its not so much upgrading, its basically just getting proper gear that I assume isnt included on an entry level bike. It all Shimano parts, and its not a peice o ****e by any means, in fact alot of people comment on the quality of the bike for its price. So its bascally what can I look to insure I can ride more safley and have more fun out on the trails. I dont need lighter, just whats some good gear to think about. I am especially new to parts.
