Off road testing is DONE on the just released Continental Dubnital and I am estimating it very close to the old RK 2.2 and Schwalbe Rick XC for Bicycle Rolling Resistance drum testing.
This is the fastest one in the mix, the Rapid Race, and in the 29 x 2.4 size. It’s 60 mm wide on a 29 mm internal width Kovee RSL rim.
As you can see, a fuzz slower than the prior RK 2.2 on cat 2 stuff… I’m doing the Dub 2.2 soon also which should be interesting.
Also notable is the, errrrr, King, of Cat 3 gravel remains the Peyote XC Race. 👑
Oh… a quick note on tire pressure. I’ve posted about this before, but this is EASY stuff. Even if you miss the optimal PSI by 1 or 2 either way, the rolling resistance value is close to identical. Ride feel changes sure… but remember this isn’t a steel drum and it’s easy to overthink casing tensions, hoop stress, and the ever present dream/fiction of a “perfect” comparison. More Testing. Less Thinking.
Tire performance is kinda wild, and that is totally okay with me. 🙂
(All gravel CRR numbers are from my own Chung Method / Virtual Elevation testing.)
