Continental GP 5000 tyres

Postby rodneycc » Thu Nov 08, 2018 10:16 pm

These tyres sound interesting. Next generation up from the GP4000s IIs.

Probably the best thing about them will be the sales of GP4ks as they are now obsolete.

Continental GP 5000 is here

Conti have finally entered the road tubeless market, releasing the Continental Grand Prix 5000 (also comes as a clincher) :

Initial European pricing is 75euro for the tubeless GP5000-TL and 63euro for the clincher, so not a cheap tyre. Comes in 23mm > 32mm.

GP4000 has been good for me, bicyclerollingresistance says all sizes are a couple of mm oversize, my 28s measure 31mm and measured (drum) to have lower rolling resistance than the narrower ones, will be interesting to get actual measurements on the GP5000 as I would be tempted to go 32 but will be tight between stays if too much oversize. I can wait till they drop in price.

BikeRadar says...

"As a running change, Continental has ended production of the GP 4000 for several months, and you will only find the new GP 5000 once existing stock in the market is exhausted..."

Should be some good end-of-stock sales around the place soon then...

Clincher in 23, 25, 28 and 32mm.
Tubeless in 25, 28 and 32mm.

20% improved puncture protection and 12% less rolling resistance compared to GP4000 are the official claims.

Speculating on the GP 4000's - how long will they keep?

Car tyres have a lifespan and if you get new car tyres that have already been sitting in the racks for 1 or 2 years, that's not the best (as I understand). So how many GP 4000's can I buy and stockpile for how long?

I'm a believer in not folding tyres to store them for later use. If there are no folds in them, then you are not having any points where the rubber has been stretched from normal and making a crease point. :wink:

I've always been led to believe that if stored in a dry, dark place then 3-4 years.

I still have a 23mm first generation GP4000 that's probably about five years old.
Still in it's box but wrapped in a ziplock plastic bag and stored in the dark.
I fitted one of a pair of the above 18 months ago, no problems. The rubber is still supple and no sign of perishing. Remains to be seen if i get my typical 7000-8000km mileage from them.
I mentioned in a different thread my impressive 12,000km mileage from a pair of 28mm GP4000 II's. I fitted them to a new bike in April 2015. They've just about had the gong.

Stupid recommended tyre pressures on the conti web site. Who in their right mind would run 32mm tyres at 85psi.

I would add, in a sealed bag or box with minimal airspace. I used to do this for R/C model car tyres and it makes a massive difference to keeping them fresh, which was immediately noticeable on the stopwatch. So I do the same with my bike tyres.

Used to cling wrap our GoKart race tyres in between races as well.
Same base theory.

Tyre warmers like in Formula 1... do they work on bike tyres?

Thats to help them get up to track temperature faster. (Much higher than standing temp)
Bike tyres are not generating the heat to require warmers, they just need a very soft compound from the get go to generate grip.
