Was looking for a rack for a carbon bike a year ago.  Decided to buy Blackburn EX-1 Disc Rear Rack.  Altough it is designed for a bike with disc brakes, it works fine with pad brakes.  The unit came with everything I needed to install on my bike.  It took a little time to get the adjustments proper.  I used it for a while in preparartion for my tours last year.  Unfortunately, COVID caused the tours to be cancel.  Will reinstall for my next tours.  The unit comes with an extended quick release to accommodate the rack.  The only limitation that I found is the need for a little more time to fix a rear flat.  Hope this info is helpful.
