The BC1412 is a pretty good computer. It only tracks altitude gain, however. It would be nice to have the same feature as the Sigman BC1612 for multiple bikes, particularly the ability to sense two different wheel sizes but it doesn't have that feature.

As for its toughness, I have no doubt that it's as good as the other Sigmas. I've had a few that have survived going through the washer and dryer more than a few times I've never had one fail even in those conditions. They laugh at a little bit of rain
