Product Customer Reviews

Tengo una btt Coluer de 2006, con este neumatico se ha cambiado en una bigfoot excelente. Me encanta!
Para un uso a un nivel aficionado, pistas y con algo de rotura va muy bien
buena calidad / precio
Bueno, buena relación calidad precio
Me sorprendió lo mucho que agarra esta rueda.
He hecho pocas salidas para poder dar una humilde opinión. Para mà que suelo ir por camino de tierra tiene buen agarre, calidad precio me ha salido muy bien. Y para mà que hago pocas salidas a la semana me he suficiente
Lo compre para la rueda delantera y tener mas agarre en zonas de barro y zonas de grava suelta y arena,tiene buen comportamiento en terreno suelto y en terreno duro,el paso en curva tambien ha mejorado,la resistencia al desgaste en buena,muy satisfecho con este neumatico,me proporciona lo que andaba buscando con un precio bajo
Buena cubierta para reemplazar a la kenda nevegal de 26" que cada vez es más difÃcil de encontrar. Tiene más balón que la nevegal 2.10 pero serÃa muy útil una versión de 2.35, perfecta para los que seguimos usando nuestras 26".
Lo tengo en la rueda delantera y por ahora en los kilómetros que e hecho con el me va perfecto.
Neumatico correcto para rutas de pista y monte
buen agarre ,direccion buena de momento con 14 salidas no ha perdido nada de aire
En las bajadas más fuertes hay que tener más grip con los tacos y más anchura de2.00 a 2.10 aunque yo buscaba 2.20
Bon pneu de XC, bonne accroche et bonne motricité sur tous les terrains. Facile à monter. Reste à évaluer la résistance dans le temps,mais c'est bien parti.
Super adhérence
Produit que j'ai acheté pour un ami, pour remplacer un pneu lisse. Facile à installer, solide, il correspond complètement à la description ! Je recommande.

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 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. On the other hand, when riding in dry weather, you can increase the pressure for better performance. Before each outing, make sure that your tires are at the correct pressure for your ride.
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.
