Once installed this tiny plastic device adds a few grams but will in 99% of cases prevent over shifting and the frustration of a chain getting un-shipped during the process of changing from big chainring to small.
Indispensable for use in events such as the Tour of Flanders Randonnee where your bike gets shaken to bits and shipping a chain is common. Once fitted this device will never need adjustment and really is worth its weight in gold. Fit one Today!
Note: Some modern frames preclude the installation of this device due to bottom bracket bulk. In these instances, an alternative device from Rotor can be mounted to frames that use a braze-on front mech.
