Bontrager Node 2.1
The draw: Simple and easy data display
One of the least expensive computers that displays power as well as temperature, grade and elevation all in one package, the Node 2.1 does a lot for not a lot of money. The unit was easy to set up and immediately connected to power meters as well as the included heart-rate strap. The Node 2.1 offers a ton of sensor compatibility, but no GPS function or the ability to download ride data. This limitation makes the Node a really good entry into basic power reading as it lacks the kind of analysis capability that other units provide.
