I have the Contego bibs. I rode 2,500 mountain miles (sled, not bike) in them last year and they're going on season two now. They are WAY more durable than my Klim Stealth bibs were. I was always dry even on the nastiest days. The butt insulation is great, my rear was always cold at the end of the day in the Stealth bibs. My biggest complaint is that the material they used for the knee pads provides little protection. I ended up laminating some old D3O mountain bike knee pads onto some other foam and making my own inserts.
I did, however, buy a pair of Klim Havoc bibs for bike days. I think it's a better pant for bikes.
