Wow!  Let me start off by saying that is an amazing looking frame.

I have always loved the feel that soft-tail frames offer, but I did not like their long chainstays.  I looked at Dean and Funk Cycles, but their soft-tail frames have chainstays of 445mm and greater. Your frame is 427mm!  I find that 430mm is my sweet spot for chainstay length.

I have to ask, with 90mm of travel, does the tire hit the seat tube when the shock is fully compressed?

Also, did the frame come with the lower shock mount that you took pictures of?

I am seriously thinking of contacting Titan to have one of these built.  Again, awesome looking frame!

Hambini did a video on this and argued that it can be done if the wall
Thickness is thick enough and the aluminium grain structure is consistent enough. However you still have the problem of steel bearings wearing on the axle as it happens with all aluminium crank spindles over time. And then I wonder just how much of a weight advantage there’s left if you built an aluminium crank spindle sturdy enough in 24mm. I think there’s also a reason why until now every aluminium spindle was oversized, BB30 or DUB. Same reason why aluminium bike frames are oversized when compared to steel. Stiffness to weight qualities of aluminium just work better that way.

For those who bought it, any updates on the comfort on the seat post, does it do a great job dampen vibrations?

Thinking about ordering the straight/zero setback one and would appreciate any opinions.
