Portable and practical
The $100 power meter
AXIOM EXTERMINATEAIR HV
If you are serious about racing or just becoming a stronger rider,
power meters will deliver incredibly helpful, accurate data during
and after your ride. Unfortunately, their hefty price tags keep them
out of reach for many racers.
The CycleOps PowerCal is designed to simplify the process and
bring the benefits of training with power to the masses with the
first power meter that calculates power using heart rate. While the
correlation is not always exact, CycleOps, with the help of the
University of Colorado Boulder, analyzed tens of thousands of
power files to determine patterns in real-world conditions. The
result is an algorithm that can predict power very accurately based
on heart-rate readings.
CycleOps is the first to admit that the PowerCal is not as accurate
as their Power Tap power meters, but at a fraction of the cost, and
with the ability to communicate with any ANT+ power-enabled
computer, PowerCal has the potential to bring the benefits of training with real-time power data to a much larger base of riders.
Floor pumps are great, thanks to their ease of use and high-volume capacity. On
the other hand, mini pumps go anywhere with you, ensuring that you always have
a back-up plan when you are miles from the car.
Axiom wanted the best of both worlds, so they created the Exterminateair HV.
This mini floor pump can easily be carried in a hydration pack, but borrows many
familiar features from their larger, garage-dwelling workhorses, such as an aluminum baseplate to stabilize the pump and a hose so you don’t have to bang your
hand against your wheel as you race to get back on the trail.
The body is CNC-machined aluminum, and the HV stands for “high volume,”
making this a great pump for mountain bikers. The Exterminateair HV comes
with a lifetime warranty to ensure it keeps going strong for years.
