Comments about Tension Knob Ring:
I purchased this as a replacement for a broken part on my Schwinn Evolution. In dimensions the part is an acceptable replacement. The problem is that the original part includes a dial indicator while the replacement does not (see image). Since there is no separate part listed for the indicator you will have to pry the original indicator off (if you have it) and apply it to the replacement part.
Original part is left, replacement part is right
