Pretendía comprar frenos hidráulicos, según la descripción y las fotos de la publicación, sin embargo lo que obtuve fue un par de frenos mecánicos que en nada coincide con la publicación

This is a 5 star product even though the handles need to be swapped as many other others have mentioned. FYI it is very easy... if you can use a wrench, then you can swap them. Very little or no fluid will spill out. Anyway, my Shimano brakes were not doing their job properly, so in order to save them, I tried flushing & bleeding the lines, replacing the pads, and replacing the rotors, but not of these things helped. I ordered these brakes based on the positive reviews, even if I was hesitant about the need to swap the handles first thing. They worked great on the first ride, with both front and read brakes gripping strong on hills. The handle squeeze has a nice solid feel so that you have confidence in your braking. After repeat on Arizona trails, they have only gotten better. I highly recommend these.

Great job

I have a 13 year old MTB and the original Promax mechanical brakes really were awful. I decided to upgrade to hydraulic brakes. Since I ride mostly through the neighborhood, I didn't need top of the line brakes. I was very suprised with how well these brakes worked right out of the box. They bolted right up with no modifications (160mm Promax rotor). I didn't have to bleed anything either. They have very good stopping power. Time will tell if they hold up or not. But for the price, if I get a few years out of them then thats fine with me.

Look at the review and everyone had a good comment so I ordered from my son bike and man it's night and day difference for the price it's a great product
