I'm posting this from the Highway 17 Express bus going home. My Specialized Roubaix 30 speed carbon fiber road bike is sitting at the front of the bus in the bike rack. As we zoomed along I-280 in San Jose at abou 60 mph THE BIKE RACK BROKE, leaving my bike dangling inches from the pavement at the front of the bus!
The bus driver pulled over and moved my bike to another spot on the rack. Disaster averted.
Apparently, those Sportworks 3-space "Trilogy" bike racks can break while in use! King County removed all of their Trilogy racks because of problems with the 3-space racks they experienced in the Seattle area that Sportworks claimed was user error -- cyclists were not properly securing their bicycles.
Santa Cruz Metro uses the 3 bike racks on all of their buses, but I haven't heard of problems until my experience tonight.
