Yes, there's a reason the choices of tubular wheelsets are diminishing. Ten years ago, it seemed that half the aftermarket wheels were for tubulars. Nowadays, it seems less than 1 in 20. They've become pretty rare. Clinchers (especially tubeless) are easier, less messy, and a lot of them perform just as well as a set of tubulars. A few perform better. Even in the pro peloton, tubulars are headed toward extinction. But they could be pretty cool as a kind of vintage, throwback option.
