These things are useless. The bolt screws directly into the pathway of the wheel axle so they cannot be tightened anymore. They should've had the bolt mounted in the axle eye with a nut on the other end so they could actually be properly adjusted. Product is absolutely no good for anything.

Very small for a chain tensioner. M4 bolts? Doesn't look like it's going to hold up. Didn't say how small the bolts were. Bolts aren't long enough. Thought bolts should be at least m6 size. Will not buy again.

Making sure your chain is well tensioned and lubricated makes your ride way easier and safe. This thing works well it keeps it from falling

Item feels flimsy and us way smaller than I exspected. It's shown in the images sitting next to one of my Samsung earbuds for size comparison. I won't return cuase it's not worth the hassle.and I can hopefully make it work on my bike.

Apenas me llego el producto, lo que alcance a percibir era que estaba barrido la parte donde va el tornillo allen, así que lo devolví porque para nada me iba a servir.La verdad difícilmente volvería a comprar este producto, ya que la primera vez me quedo mal, existen otros productos un poco más caros, sin embargo siento que tienen mejor calidad en sus componentes que estos tensores.
