ZEFAL LOCK'N ROLL Antitheft System for Wheels + Saddle

Complete ZEFAL LOCK'N ROLL anti-theft kit for wheels and saddle stem. 

Pattented keyless system.
Simple assembly, quick and tool-less.

The principle of the patent is simple: the system is locked in a normal position. The wheels and the saddle stem are then automatically locked. The anti-theft system is unlocked by turning the bike over by more than 90 degrees. 

We recommend:
1) that you tighten it firmly so as to prevent the quick release from turning in the locked position. A special washer keeps it from unscrewing.
2) that you attach the bike in such a way that malicious persons cannot turn the bike over.
 
This innovation received the Gold Award at the Eurobike 2008 exhibition.
