Howdy all. I recently purchased a Saint 10 speed derailleur because they look pretty and i thought i'd be able to buy the pictured OneUp RadR cage mod so that i can run larger cassettes, 11-42 sunrace specifically. However i appear to be about 3 years to late and i cant find one for sale anywhere. Is the goatlink a viable alternative for this rear mech or did i make a boo boo. any advice would be appreciated.
