Hello all,

I will be commuting 2 miles to law school starting next month, and will be parking in the school's parking garage. I'm assuming it's relatively safe, in NW DC and in a monitored garage, I don't think anyone will try and bring tools to steal bikes/parts.
My plan is to leave the Kryptonite U Lock attached to the rack, then lock the back wheel and frame with that. Then my plan is to purchase a Kryptoflex cable and run that through the front wheel, seatpost, helmet, and connect to the U Lock. That way I can leave everything but the lights on the bike.

Is that a good idea? If yes, how many foot kryptoflex would I need?

Thanks for helping a new rider out!
