at first glance I would say, 28s would fit. I myself don't use 26s, but the spesh turbo (pro?) road tyre comes in 622-26, Pirelli P-zeros as well. No idea about Schwalbe being thicker on the rim, haven't used a schwalbe tyre in years.
Thanks very much. Think I’m going to try and search for some conti gps4000 25s as they seem to sit bigger than 25 but will look into those pirellis as well
