Tsunami Bikes - Frame Review

My rating:  4.5 / 5 (read below to find out why)

Tsunami Bikes is a small builder out of Phoenix, AZ specializing in custom geometry aluminum frames.  I had seen pictures of their work floating over the internet, and they always struck me as well-built, no-nonsense frames.  So when the opportunity presented itself about six months ago, I decided to pull the trigger and get one for myself.

iBike Sport Review

Recently, I purchased an iBike Sport from Competitive Cyclist.  Frankly, I was in need of a new cyclocomputer, and I have been wanting to try one of these to see how well it works as a power meter so I gave it a shot.  I should clarify something; the iBike is not really a power meter but more of a power estimator because it doesn't use strain gages for measurements like other popular power meters do (Powertap, SRM, Quarq).  Instead, it measures wind speed and the road gradient, and then calculates how much power is theoretically required for a certain rider to be traveling at the given speed.  These calculations are based on several assumptions taken as constants, such as aerodynamic and rolling resistances, so there are some inherent deficiencies in the calculations (such as not being able to account for changes in positions, like going from the tops to the drops).  But overall, this test done by VeloNews suggests that the calculated real-time power readings from the iBike correspond pretty well to those from a PowerTap.
