Full suspension
Cannondale mountain bike which sells for a little under $2000. The Super V 400 uses the same frame (SL) but has lesser quality components, and is therefore heavier. Better to get a 400 (which sells for around $1100) and upgrade a few of the less expensive parts, e.g the pedals.
Personally I prefer the Super V 700 SX with the lefty fork and disk breaks (it feels about 5 lbs lighter than the Super V 400), but it's also in the $2000 range :(
I'm planning on buying a Super V in the next month.
