Abus 6950M Frame Lock. The Abus 6950M frame lock fits all standard bicycle frames and secures your bike by preventing it from being easily pushed away. Permanently mounted on the bicycle frame the frame lock accompanies you on all tours through city and country. Thanks to the universally adjustable hole spacing the 6950M can be easily attached to all standard bicycle frames. Convenience and safety go hand in hand here: the proven ABUS XPlus cylinder offers high protection against manipulation attempts such as picking. On crucial components such as the shackle lock housing and parts of the locking mechanism specially hardened steel provides greater security against attacks on the lock.
