Well that is exactly what the RR is for. I really like mine – got it in pub bike/gravel bike config at the mo – drop bars (with short stem), Tiagra drive train, BB7 brakes, 35C tyres. Rides great, efficient enough for long rides, but rugged and quite relaxed too, not as twitchy as a proper road bike. Keep meaning to put some mudguards and panniers on for winter commuting, but never seem to get round to it. The horizontal dropouts and combined mech hangar/chain tug is indeed a PITA, but I think the latest ones have proper mech hangers.
I guess alot of this is personal preference in terms of if you like the way it rides, I like the way it rides, very much an MTB feel with all the benefits of a road bike too and it is a properly rugged bike, so when you’re on a rough trail I have no worries about riding over rough rocks or even small drops.
