Yeah but I don't do 'ride slowly'! Also easier to get into the routine now, so when the stinky weather is here it's automatic...
N+2 seems the logical choice!
To be honest with the Dolomite you're in a similar boat to how I'd got myself with my Defy, a 'do it all' bike that works well so is hard to justify 'replacing' even part of it's role. For me as the mudguards I had (SKS Raceblades) were a compromise fit and coverage wise then I could justify replacing the 'winter' use of the Defy and go for my Gravel bike with disc brakes (Diverge). I'd fitted lighter summer wheels (RS81) to the Defy so also 'downgrading' back to heavy winter wheels (Khamsin - which need new bearings) also helped to sway me. Which kinda leads on to the next problem I'm finding - my 'winter' bike is my favourite and my 'summer' bike is no lighter, and not any faster!
I can see me buying an aero road rim brake frame next year and doing a new build around the 3 rim wheelsets I have (I have a deeper set of Rovals I'm rebuilding). I fancy sticking some TT bars on it too and trying some TT'ing!
