I had these mounted on my 3T Exploro Team. My bike came with 54mm Panaracer Gravelking SKs. These are much faster rolling with decent puncture protection. I accidentally ran through broken porcelain chips and had a lot of slivers in the tread but all sealed but one large piece ~1.5mm. I was able to plug it with a Dynaplug and it sealed and has been great since. On my Nobl 27mm internal rims, it measures out to 54mm. These are much one downside is that they weighed on my coffee scale at 645g and 635g ' more than 100 grams over the stated weight. Ironically, the Panaracers weighed in at 545g for a 54mm. I will say that the heavier Pirellis feel like less work turning than the light, but wider and knobbier Gravelkings. I also wish the 50mm option came in black. Otherwise pretty satisfied.
