As part of my never ending road bike refurbishment, I'm replacing the down tube shifters with Shimano RX 100 brifters. The right hand side one clicks 7 times up and down so I'm guessing it's an 8 speed one (Google suggest that RX100 also existed in 7 speed)
-am I going to be ok with a Shimano rear road derailleur RSX, contemporary to the RX100 groupset (I believe)?
-will any 8 speed Shimano road cassette be compatible?
-will any 8 speed Shimano road cassette be compatible?
Yes.
Double check the shifter, it start on 2nd when you did the first click (I know you probably do know this, but just want to make sure we're on the same pages).
