When anybody finds a way of welding titanium without introducing accumulations of brittle titanium hydrides into the weld zone, then I might consider buying one, until then it is only a matter of time before a welded titanium frame cracks.
Would you mind expanding this. I have a Ti frame and purchased it with the intention of keeping it for a very long time. However it appears that you are suggesting that all welded Ti frames will crack at some point. Cheers

My father in law has one he bought second hand last year. He loves it and now rides it more than any other bike (he has 9!). While it wasn't a Lynskey a friend of his had a Ti framed Van Nicholas and had issues with cracks.
I tried a Van Nicholas Ventus, good bang for buck, but preferred the Lynskey, slightly stiffer all be it a Ti is never going to be as stiff as a Carbon.D

Another very. Ice looking Lynskey alternative having looked at tons of Ti bikes at the cycle show) is a bike Beacon are just launching. It isn't on their website yet but is just about to go on same. I think the model they had on their stand was just over £3k with hydraulic discs and Ultegra kit.
Not sure when it will go on their website so perhaps best to call them. I think they pretty much build it to your spec though. The frame is an endurance type geometry and there's enough clearance for gravel spec tyres with mudguards so properly versatile

Funnily enough I was asking one of our structural integrity specialists (also a keen cyclist) this question this morning - I work in the nuc sector. I asked because I quite like the Planex X cyclocross frame and was wondering the same thing; although stress corrosion cracking was my concern.He wasn't concerned but then he's a SSteel specialist rather than Ti.
It is hard to weld correctly, nees very careful gas control, but does get used for safety critical components and the Russians built pressure hulls for Alfa Class boats in the 90s, which took an age to get right but did work in the end. So it can produce a reliable weld.
