UPANBIKE Bike Crankset with Bottom Bracket for Road Bike Mountain Bicycle 8 9-Speed M430 Crank Set

Though it's not a Shimano, Sram, or FSA, this Crankset and BB combo is the best value on Amazon if you're looking to upgrade both components on your mountain bike. I actually converted this to a 2x setup by removing the outer ring and using some Raceface tab spacers with the original chainring bolts. The bolts are great too because they only require two allen keys to tighten or loosen instead of the normal bolts that require a special tool. I'm sure this would be good for a 1x set up too if you were to go that route.Pros: Based off Shimano's Hollowtech series; sealed bearings; crankset easily removeable for cleaning and servicingCons: Heavy; plastic left arm bolt; made in China; manufacturer doesn't have decades of experience and quality to their name

I used this to restore a hybrid bike; this crank modernized the bike and provided correct gear ratios. Runs true with no annoying wobble. Aluminum chainrings would make it lighter (and more expensive), but the steel rings should prove durable. After all, it's a mid-grade hybrid, not a racer.

Installed this new crank and the left pedal snapped off after literally the first ride. The 2 allen bolts on the end of the pedal arm give a false sense of security. The pedal is actually held on to the crankset with a cheap plastic threaded cap which loosens up as you ride. When it falls out, so does the pedal. If you like taking long walks holding hands with your bike, by all means by this set-- otherwise don't bother. This set is garbage.

My commuter bike needed a new drive train. Plus the existing bottom bracket was cheap and I wanted to upgrade it. I ride in the winter and didn't want to invest a huge amount and found this Crankset. It was easy to install considering I had no idea what I was doing. This had less teeth than my old crankset, so I needed to make some adjustments to the derailer and now it rides so much smoother than my old crackset/bottom bracket. The cranks are longer and help for climbing hills.

I purchased this crank set. And to be honest with you. It seems to be pretty decent. First thing it does not come with the bearing press screw on the non-drive side. But you can purchase it on Amazon for cheap. It's a 20 mm. If you choose to do so. If you choose to switch out the bottom bracket or need a new one. Most of the bottom brackets will work as long 24mm spindle. But here's where it gets tricky. if you do decide to put a better bottom bracket in you're going to have to use the plastic cups from bottom bracket that came with this set and put them in the better bottom bracket. Other than that the chain rings are completely removable. And yes you can make it a single speed if you want. The chain rings are made of steel. And the crank bolts that hold on the non-drive side crank arm are steel too. Most older style mountain bikes are a 68 shell. So yes this crank said will fit. if you're going to run a single chain ring you're probably going to use one spacer on the drive side and no spacers on the non-drive side. If you're going to use the triple crank set. Two spacers on the drive side and none on the non-drive side. I hope this information sums it up for everybody so they understand what they're getting.

Nice and not expensive upgrade for your bike, after more than 1000 miles going on strong

Amazing it looks nice it feels amazing and it is one of the easiest installations ever.

This crank is made out of weak materials. It is so weak that it came apart. I had it professionally installed and when I brought it back after it failed, the bike shop told me the materials were to weak and too soft to be used on a serious bike. They recommended I find a better quality crankset and have it installed. I have used this bike shop for years with great success and respect their judgement. If you are in need of a good crankset, avoid this product.
