I really, really like Conti race kings, ride them pretty much all year round (quite infamous for my use of semi slick tyres no matter what) but the conti’s are a lot better in various conditions than most I have tried. Surprisingly grippy and very fast although rather sensitive to pressure set up, at lowish (28-34ish psi) they feel great but too high and they are not so great. And definitely go with the Black chili compound, hand made in Germany ones.
Also if you go with the race kings, go with the 2.2 (if they fit your frame)so much better than the 2.0 in fact I wouldn’t bother with the 2.0 and would say if the 2.2 doesn’t fit look else where, they are strangely very different tyres.
Racing ralphs are good too in my experience.
If you want to be “all German” about it (god that sounds horribly Clarkson-esq) rolling tests published in German magazines suggest that the UST racing ralph 2.25 and furious Fred roll best with conti race kings 2.2 supersonic and racing ralph 2.1 evo are just behind. But many will argue that these results are a little open to interpenetration and don’t mean a huge amount, as conducted on a smooth roller not a trail. Not really sure what to read into them, I guess a guide, not gospel.
p.s this is all in reference to 26 tyres if that makes any difference.
