After riding them at the worldwide launch in Tenerife and coming away impressed, I've finally got my hands on a pair of the new Continental GP 5000 tubeless tyres to review and in the above video I run through the key details and attempt to fit them for the first time. Watch to see what happens.

- Continental Grand Prix 5000 tyre with tubeless option launched + Video

It shouldn't be understated how big a deal it is that Continental, after much reluctance, has finally launched its first road tubeless tyre. We're still some way from a universal standard that would eliminate all tubeless installation woes, but Conti reckons it has developed a tyre that goes some way to minimising such issues. 

It's also claimed to be 5% lower rolling resistance and 5% better puncture resistance than the regular clincher GP 5000 tyre, due to the lack of the inner tube and the use of liquid sealant. I've been impressed with the clincher tyres that I've been riding for the past month - you can read my first ride review here.

Another proof that I'm a sucker for new gear... kiss
Just ordered GP5000 TL (28mm) for my "everyday" bike.
Current Conti 4seasons on ZTR Grail rims is a harsh ride... hence the upgrade.
Additionally have to buy rim tape, valves, sealant, repair kit. It all adds up to a VERY expensive upgrade.

I’ve been tubeless for the last two years and a bit, around 20k miles and never a puncture (that I’ve known about, though I’ve found evidence of a couple when replacing tyres). Though I’ve used Schwalbe Pro Ones, I imagine these will be as good - but the key factors for me are Milkit valves and Stans Race Sealant (you can use them together, even though both manufacturers say you can’t because the sealant blocks the valves - it doesn’t, the valves blow open at the first pump press). The Milkit valves make checking and replacing the sealant a few minutes job without removing the tyre (just a deflation to around 20-30psi is fine) and Race Sealant has coped with every road surface its seen in Scotland, England, Spain, and France. The ride on tubeless is so good and the puncture tolerance is so reliable that I’d never go back to tubes - I don’t even carry puncture repair kit these days.

I gave up on TL after one year. I was an early adopter in 2015 (Schwalbe One)

With introduction of 5000 TL my interest has peaked again.
a) It has superior rolling resistance.
https://www.bicyclerollingresistance.com/road-bike-reviews/continental-grand-prix-5000-tl-2018
b) Sealant and repair technology has improved.
c) Manufacturing quality and precision has improved. Schwalbes were a pain to fit, even with levers.
d) Rim/tyre compatibility has improved.

On a negative note:
a) Weight has not come down, still heavier. To compare:
TL = ~370g (tyre + sealant + valve)
Regular = ~265g (tyre + Supersonic tube)
b) Still need to carry tube to be on a safe side.
c) Very expensive.

I am not tempted back to TL yet... we'll see if 5000 TL turns out to be a game changer it promises to be and gets widely adopted by mainstream.

Hi,

 

I wouldn't mind seeing if you can fit these tyres to a pair of 2018 Krysium Elite UST wheels.Tried several brands and it ranged from straightforward to blistered thumbs and turning into the Incredible Hulk in the process in anger!

Pls try to inflate it with mini pump, simulating road side repair.

You should have this one in stock:

I’d assume that you’d not break the seal on a tubeless puncture, which you’d repair with worms, so a mini pump would be ok, if you did have to take the tyre off I’d assume it would be to put a tube in, again ok.

 

Getting the tyre/rim to seal with a mini pump does sound like a mission, but not sure it’s actually a likely to need to be done, ie if you can’t reasonably repair you’d switch to tubes.

Good point!

Thanks!

Well, I just installed GP5000 TL (28mm) on to ZTR Grail rims and worryingly when it is deflated the bead slips to middle into a tire channel... fortunately beads are made in such a manner that there enough seal to pump it up with mini pump... or was I just lucky?
