Thanks all ,,
the reason i want titanium is because i already own a steel tourer i built myself (surly) a carbon road bike (pinarello) and a carbon gravel bike (ribble) and would like a titanium so i don't need to worry about scratches or any surface damage to frame. I accept it may not last a lifetime but i think titanium has a better chance and will still look good in 15 years time when i hopefully will still be cycling in my 70s and i would also like to think i will have my tourer for many years also, where as my carbon bikes can easily be damaged or i may want to replace them for more modern bikes in the future.
The boken frame in particular captured my attention as the price looks pretty good and it ticks all the boxes i want from a frame, (no flashy emblems or brand on frame, hidden cables and lightness ) but i still can not fine anyone who has experience of this frame or and reviews so i am a little hesitant to spend my hard earned cash on something i know nothing about.
