My bike (02 RM Trailhead) retailed for 1K CDN, got it for 800 end of season. Since then I've spent about 400 CDN on upgrades (clipless peddles, RF Next crankset). Thus, I have 1200 in it so far. I'm likely going to spend another 600 this winter on upgrades/replacement parts (Marz MX Comp Air fork, new drivetrain bits, new stem, new seat...).
