I’ve been running a 2.35 Ikon as a rear, it’s very quick, but doesn’t particularly like anything wet or soft and spends lots of time going sideways and spinning out on climbs.. The 2.35 is pretty much true to size, so I suspect the 2.2 will be similar, but I have a feeling the 2.35 and 2.2 have different tread depths with the 2.35 having a little more grip and bigger side lugs in particular.
I swapped it for a Rock Razor a month or so back and that’s brilliant, fast rolling but the big side knobs grip when leaned over and also seem to give it extra traction upright on softer stuff. Might be a bit big for you at 2.35 though and quite a big 2.35 at that.
Have you thought about the Ardent Race? That’s a true-ish 2.2 and makes a really nice dry to medium conditions rear tyre – quite fast, deceptively grippy, better than the 2.25 Ardent ime.
