SUNRACE SP-570 Extender Link
|Description||The Sunrace Rear Derailleur Extended Link is designed to increase the clearance between the rear derailleur mech and the rear sprockets on the cassette. This useful gear gadget is especially useful where a rear mech is found to be too close to the largest sprockets to function correctly, and especially applicable on several modern cassettes with lowered (larger sprocket) bottom gears. Fits to conventional threaded rear mech hanger fittings on most frames. Includes CNC alloy bolt. Can be used on modern groupsets to extend the gear range possible with a double chainsets.
It is not what the manufacturers recommend, however we have found that with a bit of mechanical knowledge, it is possible to fit the extender link to an 11 speed road groupset (which are only available with double chainsets) and use a wide range cassette (11-40 or even 11-42) to achieve a similar gear range as a traditional triple setup.
Please contact us prior to attempting this as the possibilities do vary and damage to components may occur if you try to push the limits of the rear derailleur.
