thats really great capacity isnt it? Pretty neat bikes those Thorns.
Thank you. I do not remember who it was on this forum years ago that pointed out that the 1 liter smart water brand bottles fit in a standard cage, but he is the one that provided the idea.
I am using some old Velo Cages that were made by Velocity, they have been out of production now for maybe a decade and a half. That cage lets me mount it lower than most typical cages because the mounting point on the cage could be adjusted by a small amount.
And the cage under the S&S coupler used non-standard length between bolts (coupler is too long) so that brand and model cage was the only cage that would fit over the coupler. They also put a third bolt underneath that a normal cage could fit in but that put the bottle position farther up the downtube than I wanted.
And I am sure you saw a velcro strap on the bottle under the downtube to make sure it stayed there. I have not lost a bottle but I probably would have without the strap.
