Mine’s about to celebrate it’s third birthday and it’s been the most used bike I’ve ever owned/built. It does winter training/commuter duties with full mudguards, then I put a rack on and go touring with it in summer. I’ve never raced cross on it but I have done 100 mile chunks of the Trans-Pennine Trail and such like on it and I’ve generally taken it down paths that I used to think I’d need a MTB for.
Admittedly it’s a fair bit heavier than my Boardman carbon road bike, but it rides great in whatever mode I’ve got it in!
I’ve built some decent Open Pro wheels for it and that probably helps.
