To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was very skeptical about how cheap these are, I took the chance. When I took them out of the box I was definitely impressed for less then $50. The black coating looks very nice the machine work is clean and the bb is smooth as butter. I am 260lbs. And I do jump quit a bit. After 10 miles on them I am still very pleased. Will update with longevity.
They except them to be that nice but they were. I replace the old triple ring cranks and square taper bottom bracket with this to do a 1x on a Diamondback recoil 29er. The new set was very noticeably lighter and felt smooth. It was easy to install. I didn't use any of the spacers that came with it. It has held up great after two long rings. I don't do any big drips or jumps btw.
Because I can’t find anywhere to cont the seller I’ll just say it here. First, I have a huge problem with the bottom bracket. One bearing is super smooth the other bearing is not so much. It feels gritty and I can hear the bearing as I turn by hand. I thought maybe it would smooth out once installed but it did not. Though I cannot feel the grit I can definitely hear it as I pedal. It doesn’t matter if my bike is on the stand or I’m riding it, I can hear it either way. Second, the crankarms are quite good looking. The red color is an exact match to the other red components I have previously installed all coming from different manufacturers. Very impressed with the way they look, not so impressed with the bottom bracket.
I bought these cranks as a replacement for an old bike that was collecting dust in the corner of the garage. The bike is a 2006 Specialized Hardrock that originally came with internal cups (73mm shell x 113mm spindle) and it fit perfect. They are smooth and get the job done. I was a little disappointed with the quality. The chainring bolt hole pattern was concentric about the spindle, but some seemed a little off on the standoff.
The CYSKY Bike Crank Arm Set is a nicely packaged delivery of the Jiankun IXF Crankset. While this crankset is available from a variety of vendors, the CYSKY packaging and quick Amazon delivery make this a great choice.
The crankset itself is solid, looks good, and was free of any real defects. As many have noted, the machined parts of the crankset are a little sharp, but for the most part it all works!
The bottom bracket supplied feels silly light, but threaded nicely into my bike and so far has had done well.
The setup has about 60 miles on it so far, and all is good. Paired it up with a JGBike chainring which fit like they were made to go together.

This is my 2nd set of this crankset (used first one on a mtb). This one was for my SS bmx/cruiser. They work well, and are well made (at an excellent price!). That being said, I had to knock off one star for it not being quite as advertised. It is listed to fit 68-73mm. While it will FIT 68-73, it cannot be adjusted to BE 68mm. I wanted a 68mm crankset for a SS that has a 68mm bottom bracket. The splines and tension nut do not allow for a 68mm BB, you have to space it out to at least 70.5mm in order for it fit. I had to use one spacer on the non drive side (making it 70.5mm), so as not to deviate the chain line on the drive side (but making the pedal offset slightly wonky). It's a great crankset, but the description should read: "70.5-73mm crankset that fits INTO a 68-73mm bottom bracket". No spacers should imply 68mm (but this crankset does not allow that), two spacers (one on each side) should be 73mm, and three spacers for front derailer (two on drive side to clear derailer, one on non drive side). I get it, that it FITS 68-73mm, but it is not adjustable to (properly) BE a 68mm crankset since the splines/compression nut do not allow it. So... unless you need a single speed 110mm "old school" drop out (most city SS's, BMX, etc), this is a GREAT crankset (I LOVE it on my 9spd MTB!). If you plan on using it on a SS/110 dropout... you're going to have to offset it like I did (single spacer on non drive side).
