Col de la Vies have a different tread that goes squirly. There is a legit 650B Pasela now. I think it's been out for a couple or three years now. Also the Soma B-Sides are also basically a 38mm 650B Pasela.

I have a pair of all black 1.75" (42mm) 650B Panaracers that came on a bike I bought used. I think they're T-Serves, with plenty of life. I'd let them go for, say, $45 shipped. I Also have some brand new all black folding bead Panaracer Pari Moto 38s that I'd sell for the same.
