Question: I own a mountain bike, these brakes would be appropriate for it? 26
Document: These work. I placed them on a beach cruiser style bike that was originally and still is a coaster style bike. My wife loves them. I set them up with the &#34;Pyramid Alloy Mountain Bike Dual Cable Brake Lever&#34; The screw that clamps the cable has a holed drilled through it for a thorough vise like grip on the cable. Also when I bought the brakes, they came with their own set of brake pads.
These brakes were purchased so that I could add front brakes to our beach cruisers. Coaster brakes' reliability records with me are so-so, and as such we needed an added assurance for safety. Upon receiving these brakes, I realized that the measurements alone do not do it justice...these brakes are HUGE! They're perfect for installing over the tops of fenders or wider tires. I've installed these over some 26"x2.125" tires, and so far they've performed well.
I owned a road bike for years and these brakes remind me of the ones on my $2000 road bike in stopping power! I mean wow! I'm upgrading an old Huffy Mt. Storm and these things fit well (with an added spacer) and stop like crazy! Anyone want side pulls that work as good as V-brakes? Here they are!
Solid brakes, easy to install (I can wrench a bike, it was easy for me). Nice adjustments on the brake pads allowed me to install these on a kids 16&#34; bike where other brakes were too big.The brakes originally shipped missing the barrel adjuster on one brake, the seller was excellent and had a new barrel adjuster in the mail immediately and I didn't have to deal with cross-shipping shipping back and waiting for replacements.
I have a pro bike shop set of tools, but I do not remember bringing out more that a few common wrenches and stubby phillips screwdriver to install these brakes. You might be able to install these with nothing more than pliers, it is that easy. Getting the cables, cable housingsand brake lever installed are more difficult jobs than the caliper mounting.A brilliant design that solves a problem that there is almost no other solution to. These are a must have for increasing cruiser bike performance and dealing with steep hills.
It was almost impossible to find a set of calipers that would fit a wide tire and fenders. This ones did the job.
I have decided to give this product a 3-star rating because it was not what I expected. The pivot bolts were too short to fit on my beach cruiser. I have to come up with a creative way to attach them on to my bike. The springs had no tension and when the calipers are closed, they make a screeching noise. Other than that, they work fine with proper adjustment.
If you need to add brakes to a fat-tire project, these are an inexpensive and sturdy option. I may upgrade their rating to 5 stars after a longer mileage test.
These brakes were very nice. Even though I never put them on cause I ordered the wrong size. Company was very easy to deal with upon returning them. Even though they didn't get used looked and felt great.
You guys make me feel very happy with this parts because my bike had dfferent brakes i made the change and is amazing
