I picked up a "Gravity Attack Track" back in February and have been riding the hell out of it since. As the bike is set up from the get go, it weighs probably about 20 lbs and rides nicely. The saddle feels comfortable just sitting on it... but for any ride greater than 10 miles or so, it's really terrible. I did have some trouble with pedal strike at first (my first fg) but the frame is stiff enough to be able to easily rescue and get back on to riding. The pedals that come with the bike are pretty... well... nothing fancy. I quickly replaced them with these: http://www.giantnerd.com/vp-vp-399t-...ke-pedals.html which are also nothing special, but will work until my budget allows clipless.
Also, don't expect much from the stock tires as I burnt through my rear in just over 400 miles and I really don't skid much.
BTW: I'm 5'5" and riding a 52cm (using a single 2mm stem riser that I had laying around from a bmx build).

Hm.. what else...
The fork has a cromo steerer (Kinesis' base model fork - separately $99 I believe). Kalin seatpost looks pretty standard... VP logo on the seat and stem cap. Alex r450 rims are pretty heavy at 450g for a 27mm "semi-aero" rim. Sealed bearing Formula hubs... All-in-all pretty standard imo for $300.
