Excellent quality, decent value
Bought a mountain bike for the Mrs (Rockrider ST120 from Decathlon) but the stem was too long for her to reach comfortably. The bike has a 25.4mm diameter handlebar which is unusual for a mountain bike. 😕Fitted the new stem which was considerably shorter than the current one and it's made a drastic difference. 😊👍The new stem has an excellent build quality. So far seems to be pretty robust. Good value product. Would happily recommend.Hope you found this review and the photos helpful.

Precio/calidad bueno
Hace su función, yo la compré para probar una posición diferente, buena calidad por el precio que tiene, ideal para probar y luego comprar una de marca conocida que cuesta 3 o 4 veces lo que vale ésta.
