Easy fit

Just what I needed

icon-circle-checkmark verified purchase
Great Value and an improvement over my originals.

This set was actually Tektro upon inspection and was a very simple replacement for my original set up. The braking from this cable operated caliper is controllable and progressive. Now all I need is a disc compatible rear wheel before fitting the same on the rear of my mountain bike.

Very basic disc calipers

I have baught 2 of these to use with my road bike and they do the job. On a sunny day they're great but as soon as a spot of rain comes the performance drops more than it should. Couldn't see any other pads to try for the brakes incase I was being unreasonable.

This Is Good Product

This is my favorite

Tektro Aries

This budget range disc brake is excellent value for money. Please make sure it is compatible with your bike before buying. I have a Montra Madrock v.2017 and it fits perfectly on it. I have replaced the stock, cheap, local brakes with a pair of these, front and rear and the feedback is excellent! The model sold is of Tektro Aries. You can look up the specs on their official website before buying. Each set contains 1 caliper, 2 mounts, 1 for front and 1 for rear, compatible with upto 200mm rotor size, 1 rotor, 1 brake cable housing and 1 brake cable along with the required numbe rof nuts, bolts and washers. One of the best and cheapest if you want to opt for mechanical ones.

Need help

Disc brake is really awesome. But I'm not able to change disc pads. I tried to remove the used disc pads from the caliper but they just don't come off as there is a screw which I'm not able to open with any l-key. Please help.

Good quality, great deal for Rs 2000/-

The kit is of excellent quality and fit perfectly well on my Trek 4300 26" bike front wheel. The brake feel is very progressive when compared to the earlier V brakes. The only issue I had was cutting off the extra outer and inner cable which was long to facilitate fitting the disc brake at the rear wheel.

Nice product

Must buy very cheap than other market products used it in my btwin rockrider 340

Value for Money

Great mech brakes for the price.

Hi Justin,

Thanks for your feedback about our product! We're sorry that you were not able to fit it on your bike.

This disc brake kit fits the 74mm post mount standard found on mountain bikes, hybrid bikes, touring bikes and some older design disc brake road bikes.

As long as the packaging and labels are intact and the product is in new condition, you may return or exchange it at any of our stores.

Thanks and have a great day!

Cheap and good

It works. Took a few times to make correct adjustments to centre the calliper but once done correctly, it works quite good

Excellent Price & Performance

This 160mm Disc Brake Kit is an excellent upgrade for any bicycle with V Brakes. Before buying, do check that your bicycle is compatible with this product (Mounting points on Frame & Fork), alongside a Disc Brake compatible wheelset. This disc brake kit comes with the Calliper, Brake Pads, Rotor, Brake Wire, Wire Casing, Mounting Screws, Brackets and a tool wrench for installation. Installation was quick and easy, and it can really give you a big improvement in braking performance compared to calliper brakes.

Well worth the money

This set was easy to install on my bicycles rear wheel and frame. The existing one was an older Tektro model and the spring was no longer working so well. A pleasure to work with!
