only had it on the 29er for about a month, I’d say 3/4 of the knobs look like they’re gonna split off. Anyone else?.

More use than that and no problems here.

It’s the soft compound version. I use them on the front, on the back they wear too quickly and nobs give way. Use the harder compound on the back think it’s 60

Don’t see what difference it makes using front or back. I’ll be sending it back.

Ive got a 3c one on my bike with about 600 miles on hasn’t cracked at all

Couple of years on regular EXO 26″ version and no problems. Couple of trips to the alps and all kinds, quite worn, but the knobbles still staying on. Friends with Hans Dampfs are loosing theirs all the time.
