$27 for a 27 x 1 1/4 folding tire. No idea who actually makes it, but there are few folding 27s, so I figured it'd be a good option for some around here.
I have 2 on a bike and just picked up and extra that I will bring along when out riding for multiple days.
They ride fine- nothing impressive but also nothing to cry about.
