Since their first D-lock all the way back in 1971, Kryptonite are on a mission to innovate. Whilst much has changed in cycling since that date, their objective remains the same: to empower you to protect what you value.
From beefy D-locks, to versatile chain locks and flexible cables the company continues to set the bar for lock design and performance. During the mid-2000’s Kryptonite introduced an immediately recognizable colour based security scale. Gray offers moderate security, whilst Orange is high and Yellow is reserved for locks with ultimate security.
