Fast & Slick

Great help in store! I was going to go back and get my other tyre replaced but then they shut the Knoxfield store due to COVID19 which was a bummer. I then tried to buy it online but items were out stock which was also a bummer!

Great Performance In The City

I've had these tyres for almost 6 months now and I find them an excellent product and value. I use them on a city bike and the perform very well through the streets of London. Great grip with dry road and a decent grip when it rains. I only had one flat since I'm using them which great. Highly recommended!


Excellent tyres with good grip, rolling and puncture resistance. I am using them on my MTB. Just loved the experience so far with swift rolling and no punctures (so far...)

Nice tyres!

Loved the tyres! Using these on my MTB. I can feel the difference in the rolling resistance. Also absorbs the road undulations makes the ride smooth.

Needs Improvement

Pros: - The tire is a perfect replacement for MTB tire. - Provides good grip. Cons: - I experienced that it didn't provide much of a puncture resistance as it claimed. - In less than 6-7 months of use it developed cracks ( within tread) Even though I have been maintaining the regular pressure of 90-95 PSI and parking it in the dark area of my bedroom after rides. - The front tire bursted during night from the tread side.

Hello Sachin, thank you for taking time to review our product. Sorry for the inconvenience caused. You rightly mentioned it is a perfect replacement for MTB tires and excellent grip while riding. Yes it is a puncture resist tire but not a 100% puncture proof ready.I suggest kindly visit the nearest Decathlon store and our workshop person can have a look what went wrong. Hope it is okay for you. If you have any questions I remain available for you.

Got a bad experience as tire got damaged

I bought this before 2 months for my MTB , after riding around 500 kms, somehow I got a small hole out of damage in inner beats and eventually got multiple punctures. I had to use tire boot patch to continue but it seems it is damaged, can not be used anymore. Be careful to inspect it during/before ride to avoid such issues.

Not satisfied

I have bought this for my Rockrider 520 just 2-3 months back but unfortunately bothe the the tires bursted while standing. !st the rear one and then the front one after a week. Can't figure out what can be the issue. I have filled in around 6 bar pressure which is the minimum specified pressure for this tire. I could not get any satisfactory explanation in store as well. Now I'm confused should replace back my MTB tires or buy same new urban tires.

Puncture Free Ride almost 3000 kms done

I have replaced Tyre of RR520. Efforts to roll is less but I have issue of Road Grip. Initially met with minor accident and later on learnt to drive in control. Inner Tube is not available at Decathlon Stores but we can easily find it anywhere else. Have done more den 3000+ kms and No Puncture yet. Maybe Luck Others who have tried share your review.

Tube incompatibility.

The tube comes with RR520 which is compatible with tyres having width 1.9 - 2.5 ( 27.5x1.2 tyres doesn't have enough room to put these tube ) , So if you are planning to buy this tyre you should buy tube that are compatible with these tyres. Unfortunately there is no compatible tubes found in decathlon store both online and offline.

Totally satisfied

present my bike rolling too fast and good grip as well. suitable for all climate thanks for btwin and made in Srilanka team

Doporučuji pro silnici

Jsem spokojený s pláštěm, výhradu mám jenom v tom,že se neprodává v páru a proto jsem na druhý plášť čekal týden,až jej pošlou z Brna. Jinak bez problémů.

Montados en una ST 100.

Van genial en carretera , los he usado con lluvia y agarran bien. Se notan más ligeros comparados con los neumáticos de tacos

How to measure tire wear

To measure the wear on your tires and to know when they need replacing, you need to inspect the tread. The tread comes into direct contact with the terrain you are cycling on and therefore determines your tire's performance. A tire needs to be changed when the center knobs are worn down to the same height as the side knobs.

How to remove a tire

To remove your tire, first deflate the inner tube until no more air comes out. Once deflated, use a tire lever to remove the tire from the rim.

How to fit a tire

To put the tire back on, place one side of the tire into the bottom of the rim. Next, inflate your inner tube to approximately 30% before putting it into the tire (inflating it beforehand reduces the risk of pinching the inner tube). Then, place the other side of the tire into the rim, starting on the side opposite the valve. Before inflating the inner tube all the way, check to make sure it isn't pinched between the tire and the rim.

How to inflate your tire correctly

Inflate your tire carefully. The recommended pressure is indicated on the side of your tire as well as on its product sheet (available online). Before each outing, make sure that your tires are at the correct pressure for your ride.

Tip from the pros

When inflating your tire, be sure to inflate it to the correct pressure for the terrain you will be riding on and especially the weather conditions. When riding in rainy weather, lower the tire pressure to increase the tire's traction. When riding in dry weather, you can increase the pressure for better performance.
