New tyre day wahoo. 40mm challenge gravines replacing 38mm gravelking exts. Cant wait to ride them, I did a little up and down on the street to test and omg they feel supple. I had to get off several times thinking I had flatted, when infact I still had 30psi in there !

      Was it near impossible to set up tubeless like other Challenge tires? (I’ll never buy again)

    3. Thinking about these for unsanctioned CX racing where the 33mm limit isn’t enforced. Look like they’d hook up nice in the grass

      Challenge Tires have always been the most comfortable tires I’ve ever used. Love them. Their CX tubulars are amazing to ride on.
