Seems to be a thing … ‘mid’ (late) life crisis = titanium 50th birthday treat! 😂
I went through this earlier this year for my own 50th. Realistically didn’t have the budget for most of the options suggested above, so was looking either at nicer alloy (than my Saracen Hack) or possibly Carbon (Space Chicken/Bish Bash Bosh) or the ‘budget’ Ti offerings from Planet X and Alpkit.
Got the Pickenflick as it was reduced pre-xmas to £1300 (SRAM Rival), so full bike for the price of a frameset from most of the other suggestions above.
It’s not advertised as a ‘gravel’ bike by PX/OO, but the geo and tyre clearance figures mean it fits the bill perfectly.
It’s bloody brilliant! Great on road, and a hoot off road.
I saw a guy with the Tempest at the Yorkshire True Grit, which also looked very nice, particularly with the 650b wheels, but the ‘flick has clearance for 650×2″ rubber.
If you have the budget, by all means go for a more boutique frame/bike. But I don’t reckon you’d be disappointed with a Pickenflick/Tempest/Sonder Camino, and that might give you breathing space to spec a nice group set and/or two sets of nice wheels.
