absoluteBLACK's Chain Catcher is designed to eliminate the possibility of the chain falling in towards the frame when shifting to the inner chainring on uneven road. Chain Catcher is a simple add-on component which improves the overall function of your drive train and protects your valuable frame from dropped chains. Especially recommended for carbon frames. No matter how well you set up the front derailleur with round or oval rings, there is always a possibility that chain may find its way to drop on the frame when you shift quickly from outer ring to inner one. Especially on rough or gravel roads. Mounting the Chain Catcher in front of the front derailleur will prevent such occurrence from happening because the chain will be guided precisely onto the small ring and will not be able to go any further towards the frame. Our Chain Catcher has a conical tapered head, providing an excellent fit to braze-on mounts that are integrated with frame. However, with older frames you may use a clamp braze-on adapter. In such case please ensure that your adapter has a front face also conical (not flat). Unlike the majority of chain catchers on the market, absoluteBLACK's Chain Catcher can be precisely adjusted to ensure only minimal gap is left to the inner chainring for maximum security. - Mass/Size: 11.6g / one size fits all - Compatibility: All braze-on frames and derailleurs. - Adjustability: 6mm chainline adjustment provided on the slot for precise setup - Material: CNC machined 7075 T6 / M5 stainless steel bolt - Finish: type II anodizing

This is achieved through the use of a multi-radius bend paired with a 20mm inward roll of the bar that can be adjusted to dial in fit and achieve an ideal position. - Clean internal cable routing for easy installation - Length: 360mm
