My son rode his bike to high school, left it locked up all day at the bike racks which didn't have anyone around except at lunch hour, never had a problem. He used a Kryptonite U-lock and a beefy Kryptonite chain. He had a vintage Peugeot racer, Columbus tubing and full Mavic groupset. We siliconed ball bearings into all the Allen bolt heads that secured commonly-stolen stuff.
