Good to see the 50mm range expanding. That said, Schwalbe tires are typically undersized, I would expect this to inflate to somewhere in the 47-48 mm range.
News from the XC thread:
Sounds like a fast Conti 50mm gravel tire is in the works as well. Hopefully it’s not just a 50mm Terra Speed E25 but something faster. My hope is a Terra Hardpack Black Chili / New Speed King 2.0".
