For the owners who have now set up, how does this compare with your aluminum framed Xootr in terms of stiffness/efficiency? I know, you probably did not purchase this for the efficiency but more for the concept.

Also, how is the weight compared to the regular Xootr frame/work?

Thanks!

The weight of the aluminium Xootr Swift is 2.6kg, the Ti Swift 1.9kg.

I over-designed the tubing to be at least as stiff as the Xootr version. Calculations show it is about 40% stiffer for torsional force along the main frame part. Riding it confirms it is at least as stiff as the aluminium version which I was always impressed with.

Once you also factor in the weight of the other frame parts, that is the seatpost, fork and stem riser, the Ti Swift is way lighter. I haven't actually weighed all these bits together, but from memory, the steel Swift fork is 1.8kg all by itself. The Ti fork is around 600g.
