If you love the route less travelled, or recognise the versatility of a more versatile bike for road riding take a look at Biketart's great range of gravel and adventure bikes. It's a big category of bikes encompassing everything from fat tyred gravel bikes through to steel touring bikes for trans-continental adventures.
You need to check out the offerings from Genesis as they've been doing this a long time before it became cool. Their range covers carbon, steel, ti and alloy with bikes that cover the full spectrum.
For something rarer check out Rondo who produce high quality performance bikes with flair. Both Santa Cruz and Ibis now have gravel bikes in their lineup. Orbea have a growing range of models including electric options. Mountain bike brand Saracen offer some great value alloy models. Marin have an interesting range including some old-school style steel models for off-road adventures.
