Continental Grand Prix 5000 TL
Disclaimer: the product in this review was bought from a store and NOT funded by the brands and manufacturers who are critiqued.
The GP 5000 TL is the first road tubeless tire from Continental. After riding on them for nearly 2000kms I can say that they are grippy and puncture resistant.
Before switching to these, I was rolling on the Grand Prix 4000S II for more than 5000kms. They were and still are great. Grippy, fast and easy to install. During that time I had only one flat, a pinch flat, the tire had never punctured. But they were worn out so I had to replace them. Just in time to go tubeless and try out the new tubeless road tires from Continental.
Now about the Grand Prix 5000 TL
I have DT Swiss wheels on my bike. They are tubeless ready. I had to install a rim tape and a tubeless valve. That was the easy part.
I tried to fit the tires on the rim with my finger only as I used to do with the GP4000S2. Half an hour later I still could not manage to install them on any of the wheels AND my hands and fingers were really hurting.
Then I tried with tire levers. After some more struggle I managed to install them. Victory!
I pumped them up using a simple track pump. No hassle. The tires were seated properly. I deflated them, removed the valve core, added some sealant through the valve, put the valve core back, after which I pumped them back up. After a quick spin, nothing was leaking and the air was holding. Victory again!
The ride quality has improved since I can run them on lower pressure, at around 5bar (70psi). This means less road buzz or vibrations.
I am happy that I haven't got a puncture yet. If it happens, I hope the sealant does its job and seals it. My only worry is that if I have a puncture that will not seal and I have to put in the spare tube, it will be a hassle and painful. Now I always have to carry with me a pair of tire levers next to a spare tube, otherwise I will not be able to put in the spare tube.
One thing that I really don't like is that I have to pump them back up every 5 days or so. As I understood, some tubeless tires leak air faster than inner tubes, so I learned to live with this.
Note: the pair on my bike are the 28mm variety and they are actually 28mm wide; compared to the GP4000S2 28mm, that are actually 32mm wide.
