Tyler S.wrote a review of Schwalbe Racing Ralph Addix Tire - 29in on October 27, 2019
Familiarity: I've used it once or twice and have initial impressions
I've got this on my Ibis Ripley on the rear with the Racing Ray up front. It's used on my local trails in southeast Michigan. Mostly hardpack with some lose dirt and gravel areas, roots, and minimal rocks and sand.
So far I've tried 2.6 nobby nic, 2.6 ikon, 2.6 rekon, 2.4 rekon and this on the rear. It rolls significantly faster than all the other options. It's better climbing than the 2.4 rekon, the rekons ramped knobs don't grip very well under climbing. I didn't like the 2.6 tires due to resistance and what I felt was uncontrolled bounce.
It's currently mounted on my 35mm inner width Ibis aluminum wheels for testing. It was super difficult to get the beads set with a compressor and soap. No way I could perform a Trailside fix. I'll probably move it to a 25-30mm rim next year.
On the 35mm rim it was still more of a rounded profile than the 2.4WT rekon.
