RD01B-CAL180 RUJOI Bike Disc Brake Caliper, Aluminum Mechanical Front and Rear Caliper for Road Bike, Mountain Bike

Buen trabajo

Used these to replace 15 year old calipers that came on the bike. These work great, and were a breeze to install.

I just installed these calipers on an old Marin MTB. They work really well, and they look nice. These aren't fancy hydraulics. They don't have any bells or whistles. But why would you want your disc brakes making noise anyway?

Easy to install, nice upgrade from mechanical brakes. 4 stars because 1 caliper is very firm but the other one is soft when braking. I'm guessing I need to bleed the soft caliper, I hope it's not defective.

Better built that the factory brakes that came on the e-bike

I've had to buy MANY of these over the past year or so because they WEAR DOWN FAST. And when I say fast I mean if they're not already useless when you first install them, they're likely to have worn down significantly after your first ride if it's, say, an 8 mile ride. After going through several of these over the last couple of months, it seems that they're only good for about a week if you ride your bike at least 5 days a week, and you're lucky if you get 2 weeks of use out of them. After so many tries (purchases), I've come to the conclusion that this brand/company/model is just no good. I will not be purchasing anymore of these disk brakes.

Missing spare pads as described. Would rate higher if not missing from my purchase.

I bought these to replace the cheap no name cable actuated brakes on my ebike. These stop better, make less noise and stop so much better. I can't compare these to more expensive brakes, but I am happy with them so far. They were easy to install and haven't had to adjust them yet.

Easy to install, perfect fit and have strong braking power. I replaced the original “ nickel” sized pads and callipers. Reused original mount on the rear. Pads come installed in callipers plus two spare sets of pads.

Good quality

Étriers de frein achetés pour mon vélo Fiido m21 , adaptation parfaite sur le vélo que j’utilise en montagne ou les freins sont une nécessité. Cela chance des freins de trottinettes d’origine . Là je me sents en sécurité. Super.

Fonctionnel et suffisant, ce kit fait le job ! Excellent !

Ottimo per ora Ottimo prodotto già montati e ottimo la regolazione manuale in oltre alle due pinze già comprese di pastiglie si aggiungono un altra serie di 2 coppie di pastiglie
