That sounds like a FD alignment issue Leah. Regardless of the shifters in question, I assume you mean the Sunrace "One at a time" ones, moving the chain from ring to ring should work easily as long as the FD is set up correctly and cable tension alright. If the FD is too high above the largest ring it will be sluggish to go up or down. I'd ask the next mechanic to ride it themselves, both before AND after any adjustments.
Unless that is all working well, a new shifter won't do anything ! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
