I am also using the 50t TA ring.Dereck said:can i change my 53 tooth chain ring to a 50 on a regular 9 speed ultegra crank?
I have a 50T TA outer on mine - from Branford Bikes - with a 38T Salsa inner ($22.00, ordered through LBS). Otherwise, all Ultegra 9 speed.
Shifts as well as it all did with the 39/53 Ultegra comes with. All I did was drop the front derailleur a fraction to match the smaller outer ring diameter.
