I wouldn’t buy a Cutthroat primarily as a road bike. It’s designed around 29er mountain bike tires and I don’t think it’s recommened to go much below (maybe?) 700x45. It works perfectly for me as a gravel bike though and is decent on the road for what it is.
If you’re primarily looking for a comfortable road bike with a higher stack, I’d point you towards a Trek Domane or Specialized Roubaix. The Domane seems to have a pretty high stack to reach from what I’ve seen, and it can run bigger tires (700x38). I have a Roubaix and it’s an awesome bike.
I’m a big Cutty fan. Had one, sold it and shouldn’t have, buying another once my CFO (wife) approves another bike. She has a Cutty and is more than happy. I did set up two wheel sets. Stock aluminum with 48s. Second set carbon with 34s for road and smooth gravel. The model with AXS and a dropper, my wife’s, is my next bike.
Just keep in mind if you use this as a road bike…you’ll need a boost-spaced wheel set. It’s going to be alot easier to find light and/or fast road wheels for a standard road bike.
My Cutthroat is 2-2.5 MPH slower than my Roubaix for the same power. It’s about 3 lbs heavier, has wider bars, and the heavier/knobby tires all play a role.
I’d agree with @FrankTuna. It’s not going to win any races but you’ll be comfortable and ready to do whatever comes next sooner, like drink beer. The guy that bought mine I still ride with and with the carbon wheels he doesn’t have trouble keeping up with our group of old farts. He is 15 or so years younger though.
