Can they be relied upon to hold up to the advertised 20 lbs. Specifically, would one be acceptable for a approximately 200 mile trip on the GAP trail. I won't be camping so my load will be minimal. I ask because I don't have rack eyelets on the bike I would like to use.
A related question, is it a bad idea to run just a rear rack (of any type) only, if I am carrying only a light load.
