Logging Miles

I've discovered there are many options to logging bike mileage. Since I can't decided which to use, I picked three to run through the trials to see which one I like best:

• http://www.bikejournal.com
• http://velod.com
• http://www.mapmyride.com

I'm looking for something web-based, easy to use, and that tracks cumulative miles. Any bonuses would be nice, for example I know at least two of these sites keep track of component wear and tear.

If you have a mileage log that you prefer, I'd appreciate the advice.
