I have a QR style seat post mounted rack with a pannier loaded with a few items. Jeans, shirt, socks, underwear, belt plus my Dell XPS13 netbook and a few accessories (no power supply though). My home scale will not register the low weight, but the rack is labeled for 22 lb. I doubt its loaded anywhere near that.

My question is about keeping the rack attached while the bike is on the front rack of a bus. Its 15 miles of highway to the train station and I was wondering if you folks would recommend removing the rack from the bike during the drive. I can remove the bag instead, its almost the same level of PITA as the QR rack. I might do that anyway but if I don't....

Its an express bus so no other stops to worry about someone digging into my bag. I figure that its not going to be any worse than a big pot hole or ledge/lip I hit while riding as the bus tires, suspension and bike rack will take some of the shock.

Just looking for opinions on this.
