  • Was wondering if I was the only one who had good experiences- both of file tread and SK, only 3-4 punctures across 4 pairs.

    I’m on the new GK+ 32c tubeless on the road bike now and they’re great aside from the side walls don’t seem very well sealed, loads of sealant bubbles out over first couple of weeks and they don’t hold air well at all (lose 20 out of 60 psi over a week). They do ride great tho.

    Compared to Pirelli Cinturato/GP5000 Which side walls were completely clean and hold air well and no leakage from the side walls. Considering swapping to 32c gp5000 but worried that they’re really soft and will wear out/get bad cuts quickly.

    Not ridden them myself but considering them at the moment. Just spoke to the mechanic at my LBS and he reckons that GP5000 TL (tubeless) are better than standard GP5000s - thicker and puncture less. GP5000 TL > GP 4000, but standard GP5000 < GP4000, according to him.

    I'm not sure anyone is finding that GP5000s wear out fast, @skinny said this recently:

    I ran a pair into the ground commuting and training over winter. Several thousand km and many across shithole London. Not a single puncture.

  • Front is still on and over 7,000km
    Rear did 5,000km ish.
    The bike was used before I got it on a media trip, so will be a little higher, but not much.

    So year, they wear well.

    The tubless ones are anything but fragile. I commuted 90km across london, I pulled glass and all sorts out of them, yeah they had cuts, but all sealed on the own. Eventylly I got a big tear on a nail, but I plugged it. I replaced them not long after as they were getting well worn.

    I am runnign some wtb exposure on the back now, they seem just as durable. Not sure on RR.
