Love the Cannondale, and old school GT.
My rides is currently a GF Big Sur, spec'd in XT shit, Manitou Fork, yadda yadda. Aluminum frame, carbon chain stays.
Previous ride was a new 2007 Trek Fuel Ex 8 with a few upgrades, as well as a custom wheel build, blue Chris King Hubs laced to Salsa Delgado wheels, DT Swiss spokes and a blue spoke nipples. Broke the frame in half, got it waranteed and sold it.
Previous to this, I owned a Cannondale F500 with XT, pretty much was one of my favorite bikes. Learned alot working on it, and it took a massive beating.
