Product Customer Reviews

Excellent service at the Coventry store very helpful and patient staff my tyre and inner tube was out of stock they showed me how to log on and order for next day Many Thanks
great tires
Gute Qualität und guter Grip. Die Reifen haben ein etwas lauteres Abrollgeräusch als die Reifen die beim MTB im Original montiert waren, aber das stört nicht weiter.
Pues mi experiencia de compra online no me ha dado ningún problema y estoy conforme.
Excelente agarre en lodo y arena mojada y nieve , pesa un poco pero da seguridad. Mal agarre en piedras mojadas, musgo, ramas mojadas.. etc
Aun sin probar debido a la climatología, pero la pinta una vez montado es muy buena
Buena calidad -precio
Neumático muy competitivo al precio que tiene. En el tiempo que llevo usándolo he notado un buen agarre, sobretodo por caminos. El desgaste que sufre es similar a otras neumáticos.
Tiene buen agarre y de momento cero pinchazos
Máxima adherencia en todas las superficies ,excelente
Mucho agarre que permite el control máximo de la bicicleta.
Supongo q por lo q me costo la bici calidad precio no esta mal pero claro ahora la empiezo a usar mas y veo q hay q comprarse otra d mejor calidad
Fue muy buena la atencion
Sustituyendo a una cubierta de otra marca teóricamente buena pero realmente floja. Llevo 1600 km con ella en la rueda trasera y estoy muy satisfecho. Muy buena cubierta
En primer lugar, los tacos venían mal alineados, no eran simétricos. El acabado era bastante malo. En segundo lugar, su peso es de casi 1KG. Y para finalizar, aunque esto ya es a parte de la cubierta, lo compré online y en el momento de recogerlo me dieron uno de BMX, así que tuve que esperar tres días más. Mi consejo es por 3€ más comprar un Hutchinson Gila por ejemplo.

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 is in direct contact with the terrain you are cycling on and therefore has a direct influence on the 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 your tire back on, first start by placing one side of the tire into 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. On the other hand, when riding in dry weather, you can increase the pressure for better performance.
Tubeless ready
This tire can also be used as a Tubeless tire (without inner tubes) when fitted to a Tubeless rim. Apply a special tubeless liquid sealant to reduce the risk of punctures and improve air tightness. Preferably use a compressor or a high-pressure pump to inflate tubeless tires. Tubeless Ready optimizes grip and offers outstanding comfort.
