I've been riding a rigid SS the last couple of years (was my only bike). Prior to that, I had '05 Stumpjumper HT 26er (base model) as my first 'real' mountainbike.

To take it 'easy' on my knees, I decided to build my first FS bike - Rockstar V2. I haven't ridden it as much as I'd like to, but my first impression on it was 'Wow, so this is what a FS bike is like'.. Very fun to ride.
