Did you install the same exact rings as what came on your Corsa?

Thanks for the input.
Been so long, not sure I remember. I have 155 mm crank arms, and the big ring is ~55, bigger than the stock. I never noticed any additional effort from the "larger" Q-rings, which makes sense since they are not larger in the "dead" area. The PR on the Rotor site says to go up some, or used to anyway.
