I'm very interested in a switch to ^50B wheels which are 38mm OD smaller on the bead, so 19mm lower on BB height if I switch wheels assuming the same tyre profile height. This would give a BB height of 269mm with 175mm cranks, does this seam to be too low?

I like to ride back roads and dirt / gravel tracks when touring.
