Have recently built up a Bowman Weald and I’m loving it so far. It replaced a custom steel chesini that was not ideal as a winter bike as non disk, tight clearances and guards were not a good fit.
The Weald is a far better ride but despite buying it as a winter bike I have ended up with something far more versatile and intend to ride it a fair bit in the summer too. FWIW my other bike is a Pegoretti so I know what it’s like to ride a bike that’s fully sorted ride quality wise.
What surprised me most about the Bowman is how it’s not compromised despite being slightly longer wheelbase and wants to ‘go’ like a race bike and has impeccable handling, I doubt you will be disappointed with any of the frames on your list but I wouldn’t swap mine for any of them!
Here it is in full winter mode:

Something ti from Reilly?

I’ve had a Fairlight Strael for nearly 3 years now. It’s done everything I’ve asked of it – including a 2,100 mile 3 week trip across Europe, Scottish winters, and some frankly absurd loaded riding on Norwegian singletrack. The wise range of frame sizes enabled me to get a near custom fit. Can’t recommend the Strael highly enough!

Shand rizello disc, custom geo and they’ll do what you want. Also rides lovely, previous bike was a Cervelo carbon aero thing and it was good but didn’t really sparkle, the Shand is heavier and less aero but feels so much nicer.

4 season bike, you say.

Have you overlooked the Kinesis 4S Disc?
Will take 30mm tyres comfortably – probably 28mm, with mudguards.
Capable of (not particularly smooth) canal towpaths along the Kennet and Avon and a gravelly fire-road blast through Savernake forest (although I did pinch-flat on that one)

Maybe a toss up between that and the RTD

I guess other considerations are to be able to run up to a 28 mm tyre size

i forgot to add, those are hutchinson storm 28c’s with sks guards. i did take the plastic clip off the front tip of the guard but there is no rubbing and they were not difficult to fit apart from not having a proper blade to cut the stainless stays. i’ll be on 32’s come the summer when the guards come off. wheels are quite wide so the 28c measure 29.9 with my vernier gauge.

Does it have to be metal? I’ve just done a similar thing. I have a ‘fast’ bike and wanted a good all rounder, winter road bike, gravel bike all year round, occasional bike packing and ended up with a SC stigmata. The Cervelo Caledonia looks like a great all rounder if you want something more road focussed. I’m sure there’ll be other carbon all rounders. I’m not saying don’t go metal, but I wouldn’t rule carbon out.

I give up trying to share Instagram images…

I’d avoid cheap titanium – the frames at this price point are heavy, and I’d be concerned by their durability and ride quality.

Ritchey Road Logic Disc – the non-disc version was superb, I can imagine this version will be just as good.

Focus Paralane – a real sleeper bike. Granted, it’s not metal, but I thought it was superb, and worth a mention. Loads of tyre clearance, comfortable, relaxed geometry and light.

Trek Crockett Al – a leftfield option, don’t be put off by the CX marketing, these frames are brilliant for the money, although the prices seem to have gone up for the 2021 model.

Given that @forked has recommended the Trek Crockett here’s mine.

Bought and used as a spare race CX bike it’s now done the vast bulk of the almost 7000 miles I did last year as a road bike including several 200s.
But it’s not as pleasant to ride as my Rourke 953 road/best bike which I’ve also done 200s on. Given the option of going down that usage again I’d look at an 853/953 frameset with the ability to fit tyres 28-40mm and guards. I can’t comment on any of the bikes you’ve listed but friends have good things to say about Mason and Fairlight.
The steel Rourke replaced a Carbon Storck so it was a pretty high bar to match. The Rourke has been better in every way apart from weight but that hasn’t stopped it being faster.

Ritchey Road Logic Disc – the non-disc version was superb, I can imagine this version will be just as good.

Came here to say that.

get a test ride from a dealer.
