Product Customer Reviews

What's the weight of this item?
My old bike has a 23mm seat post, I found this product that says it's 23.4mm - that'll do I thought. I went to my local Decathlon, found the item, clearly marked up and advertised as for bikes that take 23mm (certainly no mention of 21mm anywhere), It looks like a decently made product and I don't know if mine is defective? it definitely has 23.4mm printed on it. Anyway, I didn't have my vernier callipers on me at the time to check so it was only when I got home and tried to fit it that I realised it is way too thin. I didn't intend to use an adapter but I tried both the sleeves that came with it, one was still too thin to tighten up the post enough to actually ride (the seat would still turn and no doubt sink if I sat on it), the other wouldn't fit into the frame with the post in it at all. So if you are looking for a 23mm seat post this probably isn't the right product (even though it says it is)
Hello. Thank you for your feedback which is very interesting. I have measured a couple of the seat posts currently in store to double check for any error and they measured up at 23.4mm as advertised. Please do return the seat post to your nearest store to be double checked and swapped for the right size if required.

Good product - a replacement for my previous seat post.
Instalé la tija en la bici de mi hijo con uno de los adaptadores y no termina de sujetarla, con el uso se va bajando y hay que subirle con demasiada frecuencia. La tija está bien pero a mi no me sirve.
Hice el pedido online, pagando el coste extra por entrega en 24/48 h y resulta que el artículo viene incompleto. Imposible contactar con el servicio de atención al cliente. El COVID les sirve de excusa perfecta para no atender las llamadas
Saludos, Ruben, Monitor País de ciclismo,
Muy robusta y de buena calidad, trae 2 ajustes para que encaje. En mi caso usé el de 25. Estupenda para subir la altura del sillín de una bici de 24". Gracias
Lo estaba necesitando y me va muy bien, gracias.
Tosca y pesada
Fácil de colocar y buena adaptabilidad por disponer de varias opciones.
Muy buena
Cumple lo que promete. Buena calidad de los materiales y genial los adaptadores, evitan cambios y devoluciones. También de gran resistencia.
Producto sencillo que cumplió mis expectativas
Está destinada a una bici bastante pasada de moda y no se trata de hacer una gran inversión, por lo que su relación calidad/precio/peso es adecuada; las habrá mas ligeras, pero de mayor precio, asi que estoy contenta. Trae además dos accesorios de ajuste al tubular; pero como digo, el cuadro está desfasado, por lo que he no me ha servido ninguno y he tenido que hacer un "apaño" a la vieja usanza para que el sillín quedara fijo y alineado. Aunque eso no es culpa de la tija...
Estoy devolviendo a la carretera mi antigua bicicleta.Esta tija me a facilitado la vida gracias a sus adaptadores. Muy buen diseño. Se adapta facilmente a cualquier asiento.
Parfait pour vélo de course vintage,bon rapport qualité prix,poid correct et look sympa.
