A more usuable review…
I used 2014 Performance Ralph OEM on the rear of my Anthem for ages. They felt fast, lasted for ages and never gave me any issues, although I’m not a man of great lean angles. Its worth distinguishing between the dual compound Performance 2014 onward, and the single compound before that, the latter being a liability as above.
I went to Battle of the Beach and sliced one on a shell. The nice Schwalbe man and some other chaps – both of whom I owe coffee too – gave me a Ralph Evo to replace it with. Back to back on Pembury Beach the latter actually felt as though it has a lot less rolling resistance. Both tubeless, both 30psi.
As I’ve said in response to your question in the XC Racing thread, if you read the Rolling Resistance review the Ron is actually a faster tyre and by default then more usuable. I let mine wear so the Ron actually becomes less prominent in the centre when summer occurs, meaning I never change the tyre and essentially purchase 1 x Ron Evo Snakeskin throughout the year.
