Average weight of D locks?
What is the average weight of a regular Tioga D lock?
No idea. I have no interest in a lock that is not rated "gold" or "silver" on the soldsecure.com website. The lightest "silver" rated locks weigh two pounds (such as the Kryptonite Evolution Mini u-lock and the OnGuard Mini TC u-lock. "Gold" rated u-locks weigh five or six pounds (such as the Kryptonite Fahgettaboudit u-lock)
A lock that can't past Soldsecure testing is not actually a lock. It is a sign that says "Free bike here".
