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.
