We don't keep bikes at the COOP. Easy rule to make to ensure an un-tagged bike isn't mishandled/sold.
I told her IMHO they needed attention and suggested she contact our full time employee to see what he thought or come back as I was out of ideas without doing research that we didn't have time to do right then.
She took it serious enough that we discussed overall safety and I expressed my opinion that while one "could" ride the bike with the cross brake as they were working perfectly, I wouldn't recommend it. Bike also has front derailleur issues and a bent barrel adjuster preventing tuning. So she left knowing the bike still needed repairs.
Thanks for your input.
