Just for giggles (actually peace of mind) you should invest in a good quality "U" lock or a big chain lock. It would be a shame to lose the bike, and cables, even many of the real big ones, are not a lot of protection. Big city folk tell me that using two locks is the way to go. Personally I use a large Kryptonite chain lock along with a alarmed rotor lock, depending on where I am leaving the bike.Picture from this morning's commute (03/01/2018) - Denver, Co - average temp: 23 degrees F - Juiced CrossCurrent SView attachment 20173
