Are you worried about reliability of the Chrome strap, or straps in general? Messenger and bike-culture types around here like Chrome messenger bags for quality and reliability, especially the clasp. I have a basic Timbuk2 which makes a decent briefcase in the car and on brief walks. The detachable cross-strap has a spring loaded clasp for the attachment at the low end of the bag, and that failed after about a dozen uses. I haven't replaced it because I haven't been using it as an on-bike cargo bag. Until now I've only needed to carry very light loads, and I've used an ancient Eddie Bauer daypack for that, just a triangular rucksack.
