An American Touring Bike

[Gravity Aided]

That looks to be about the same size as my Traveler. Never come across Tenax before.

I think this may be a 25", from center BB shell to top tube, just the upper limit of my capability. But the top tube is shorter than many other bicycles of this size, due to the relaxed geometry. I think my previous Passage was a 23", which is almost perfect.
