I'm looking to get a computer for my bicycle to give me some more information when I go on rides. I have seen and used several that belong to friends, and while they seem invaluable, the one feature they all lacked was data logging(more than simple avg. speed, avg. cadence, etc.) and the ability to pull that data onto my computer. I'd love to be able to make some graphs of my rides so that I can track my progress, this seems simple enough that it must exist, I've just had no luck finding one.

Ideally, I would like it to have the following features:

• Speed and Cadence sensors
• Trip functionality
• USB interface to get data the data onto my computer.

If anyone has any recommendations for a good cycling computer it would be greatly appreciated!
