I'm new to this place and rediscovering mountain biking after being away for a bazillion years. I last raced mountain bikes when Rockshox Judys were all the rage. Yes, I'm that old... But back on topic, I bought a used 29er Redline Monocog yesterday and wanted to get some opinions on it. It's got upgraded everything, including an SID SL shock and top-of-the-line Avid disc brakes. I got the bike for $400 and it was originally owned by a mechanic/racer who maintained it pretty well. The frame looks new still BUT he raced it heavily. Do you think it was a good purchase? I wanted something to ease back into mountain biking but I don't want a throw away bike either. I don't have crazy spare income like a lot of you guys. lol. Was this a good purchase?
