I use the "Other" gear to track parts on my bike (e.g. tubes, tires, etc.). It would be great to be able to optionally associate these items with a bike that I have listed. For example, if I have just gone through the original tube, I would create a new "Other" gear item for the tube then I would want to apply that to all previous cycling activities to get an idea of mileage I got on that tube, and then to be able to add in a new tube and retire the dead one. Of course, if I have more than one bike, this method would add that tube to all rides for both bikes!
Thanks for your consideration!
