Difficult to make up one’s mind based on these kind of threads.
There are just too many variables:
people 1) ride differently on 2) different terrain with actually 3) different tyres even if it’s the same model (compound, width), on 4) different width rims and 5) pressure can make a huge difference, too AND nobody ever has the complete picture, because if they say “this the best tyre ever” you never know which tyre they have ridden in comparison etc. see the 5 variables above.
BUT you can try to get a rough picture and it’s always nice to read something that exactly corresponds with own experiences ! ->
If you have a smooth riding style you’ll like them, if you prefer to hit the corner hard and drop it on its ear they are not the tyre for you. They respond very well to controlled riding
So here’s my piece of variables
– had a pair of Nobby Nics evo 2.1 on hardtail
– in addition to what has been said: found them surprisingly good at sticking to humid sticky-clay-y soil
– never liked their “grips-better-than-you-think-but-you-can-never-be-completely-sure-about-it”-feel
– but again: it depends on how you ride!
– I ride mostly forest singletracks, packed to loose, sometimes sandy, few stones, some roots
– like to ride aggressive into corners, also like to thread like a needle through tight twitchy stuff, not very technical riding though
– run much lower pressure (below 2 bar) recently as new tyres (below) like that more than Nobby Nics
I have tested a few tyres recently and found 2.2 Purgatorys and especially 2.4 Ardent on the front much more to my liking.
So as I said: Difficult to make up one’s mind based on these kind of threads ’cause I can’t compare either as the Nics were 2.1, new tyres are wider and I (can) ride them with lower pressure… 🙄
Hope you get a picture nevertheless! Cheers! 🙂
