Getting rad on a fixed gear shouldn't be so expensive!
The Poseidon FX has a raised bottom bracket which prevents pedal striking even on the steepest of drops. The head tube angle is slacked so your toe doesn't hit the front tire when turning. This also offers a slightly softer ride on rougher terrain. On the small frame in particular you will see that the head tube angle is slacked the most as toe overlap is a common problem for smaller frames. You can pedal freely even through the tightest of turns on that size.
