Decided I needed a wider tire for SBT GRVL this year so purchased these in 40mm width. Easy to mount. Great handling and feel like they roll faster than either the 35mm GK SS or 38mm GK SK that I have put several thousand miles on over the past few years!
I have put over 350 miles on these tires so far on some rough roads and even some trails and they have held up well! They roll fast, might not be the best for cornering, but again, pretty great for an all around tire. Would recommend!
Upon reading some reviews of this years Unbound gravel course (north bound) I decided to go wider and add some more traction. My research pointed to GravelKing X1's and I snagged a set of the 45's. They did not disappoint! To break them in I rode single track up at Red Mountain/Soapstone open space in NoCo (north of FT Collins, CO a couple weeks before Unbound and I was pleasantly surprised how well they roll while also handling the rocks and sand. No regrets here. I have found my new go-to gravel tire!
I needed something with more grip than the Gravelking SS I had but didn't want to add much rolling resistance. These X1's don't feel like they slow me down at all and make very little noise when rolling fast on pavement considering how much tread and grip they have. (Note: the 45mm tires measure 46mm in case anyone is curious)
