Murrob Posted January 20, 2022 Posted January 20, 2022 Hey All Just as a matter of interest, anyone else seeing this on their GP5000 TL tyres? See pics. They have about 2100km on them, never abused, always pumped up with tyre pressure being checked. Tyres must be about two years old (I’m mainly an mtb rider, but enjoy road as well on occasion) and the bike is stored inside the house, so no exposure to chemicals or solvents. I use car wash soap to wash the bike and drive train gets cleaned with Smoove solvent, but I am always careful not let it drip or mess anywhere else on the bike. I see on some overseas forums guys have had some similar complaints where Continental replaced the tyres. In SA, the rep was less sympathetic, when LBS raised it today, although to be fair had not seen pics. But I am disappointed for sure as they were not cheap. I have replaced them with a set of Pirelli using the same sealant, so will monitor and see how the Pirelli’s go. But personally would not trust the GP’s in their current state round a corner… Anyone have any thoughts?
warick_wrx Posted January 20, 2022 Posted January 20, 2022 I would think it's most likely due to the age. Furthermore it is seems to be a fairly quite soft compound so perhaps that contributes to it as well. Nothing lasts FOREVER !
JulienR Posted January 20, 2022 Posted January 20, 2022 my contis have done exactly the same thing (maybe a little worse) ...also about 2000km and a year old. i have also stored my bike indoors
bleedToWin Posted January 20, 2022 Posted January 20, 2022 Sucks on such an expensive tyre, but yeah it looks like age, not mileage. The rubber on these are super soft and mainly expected to be used for a single race season.
eala Posted January 20, 2022 Posted January 20, 2022 It happens to a lot of tyres .MTB tyres too . Rubber perishes if not used often .The softer the rubber ,the quicker the process
buckstopper Posted January 20, 2022 Posted January 20, 2022 Bad manufacturing quality if you ask me. To pay R12-R1500 per tyre for such rapid deterioration because it's a Conti 5000 and then to expect them to wear faster, because they're super fast or some rubbish. I don't buy it. I don't believe they live up to their reputation.

sirmoun10goat Posted January 21, 2022 Posted January 21, 2022 I see the same/similar thing on my Bontragers. spoke to Trek, they said it happens, not to worry. I have since gone on to ride the tyres till the canvas showed. When I replaced the tyres, I had a good inspection of the inside. No evidence of cracking. There is a strong inner layer which keeps it all together
buckstopper Posted January 21, 2022 Posted January 21, 2022 I run Schwalbe Pro Ones since 2017. About as fast as you can get. Never had this problem. But then I only race for fun... EddieV 1

So it’s not just about age. Combined with the weird thread that comes off the sidewall as well that I had to cut off fairly often, I wonder about the QC. Also, for me personally I have to think that this ‘perishing’ affects grip, which I am not prepared to take a chance on. I agree the casing should be fine, so I don’t think it’s a catastrophic failure on the cards, but I take longer to heal now…and certainly am not prepared wonder every time I go through a corner..

But then I only race for fun... I’ve also only heard good things on the Schwalbe’s. I have had a fairly long riding career in my youth and having worked in the industry I don’t recall ever seeing this on tyres that hadn’t been standing outside in the sun deflated for ages. I also now only ride for fun and fitness, so maybe I didn’t push them hard enough 😂
