SUNRACE Dropout EXTENDER Hanger Rear Derailleur extension like wolftooth Link

This Link provides the extra clearance between your rear derailleur and cassette

Ideal if you find your rear derailleur is too close to function properly on your cassette

Sunrace SP570

7075 Alloy Design

CNC Machined

Approx 22mm (centre to centre)

Ideal for most wide ratio cassettes with lower gearing

Note: 

It will not extend the overall gear difference capacity (or chain wrap) of the rear mech in the complete system of number of teeth difference on the bike (counting both front and rear combined) – as this function is governed by the jockey wheel cage length.

However, where single chainrings are employed on a bike in favour of double or triple, the overall gear capacity of the bike’s transmission will be reduced – and hence, the ability to handle a larger rear sprockets by the rear mech can be of use.

Typically, the Extended Link will allow a rear mech with a maximum sprocket size of say 32T to function with a 36T sprocket – so long as the overall gear capacity (chain wrap) remains within the capacity of the rear mech.
