As the struggle for supreme power continues in the realm of cycling power meters, price is rapidly becoming as much of a consideration as accuracy.
The latest in the out-cropping of affordable power meter solutions, comes from the the crowd-funding campaign of Tempo.
Using a similar design platform to that of the popular Stages power crank, the Forida-based Tempo reduces costs by virtue of the fact, that the purchaser supplies his or her crank arm, and Tempo simply installs their sensor to it, via a high strength bonding adhesive.
The sensor itself is encased in an impact and water resistant plastic molded case, which measures 33mm x 60mm, and is just 10.5mm thick.
The Tempo power meter is currently available to fit most Shimano cranks, as well as some FSA models, with the goal of developing a carbon fiber compatible version in the future.

The Tempo power meter is a crank arm based power meter full of features and performance. Some of the notable features include:
As of now here is the current status of the project:
Funding is needed for inventory, housing tools, software licenses, and test fixtures. None of the funding is for development since the unit is already working.
What are the dimensions of the power meter?
-The unit is 10.5mm (0.4 in) thick, 33mm wide (1.3 in), and 60mm (2.4 in) long.
Is the power meter going to be 3D printed or injection molded?
-The power meter case will be injection molded using high quality plastic. It will be resistant to impact and water. The 3D printed models shown are only for prototyping. The funding will be used to make the injection molded tools.
Can it measure cadence?
-Yes! The meter can report cadence without the use of a magnet.
How is it attached to the crank arm?
-The Tempo power meter is bonded to the arm using a high strength adhesive. There are no pockets or cuts made to the crank arm thus keeping is original structural integrity.
Are carbon crank arms available?
-Not yet. Once the campaign is successfully funded, we are going to proceed and being to develop units that will work with carbon cranks arm

Thank you for reviewing our power meter, we really do appreciate it! We would also like to say that we do offer cranks with the power meter installed. The customer is not required to send in their crank arms . They can purchase the entire unit and we will ship them a calibrated unit attached to the crank arm of their choice. Best Regards,
Tempo Power Meter Team
