Review: Perfect replacement for an FSA Comet crank - I wrecked my old original FSA Comet crankset (tore the spider apart somehow) so I needed a cheap replacement, fast. This crankset delivered. Despite being 5mil shorter than my old crank, it worked perfectly and I don't notice much of a difference besides a slightly faster pedal stroke. Easy to install since it fit my old bottom bracket perfectly. It also actually comes with a bottom bracket, but since mine wasn't broke, I didn't bother with the new one. Besides that, it's a crank and does what it needs to. The arm bolts to the crank thru-axle with two allen bolts so you don't need any crazy tools to install it. The only 'cheap' part on this is the endcap which is plastic - however the cap doesn't serve much purpose besides sealing off the thru hole from mud so the plastic is fine. I've been learning how to bunny hop so I have been really hammering on this crankset (along with typical MTB trail rides) and it holds up amazingly well. I'm honestly kind of surprised because I had much lower expectations. Highly recommended. No frills packaging, but who cares, it was WAY less than 100$ and had it within a couple of days.
Review: Huge improvement over stock crankset - I bought this crankset because I decided to completely replace and upgrade the stock drivetrain on my Schwinn Al Comp Walmart bike. I love this new crank set. I converted my 3x7 to a 1x7 and my bike has never felt so solid. The install was very quick and easy, but with a couple caveats below: Make sure you buy a bottom bracket wrench so that you can install and tighten the new bottom bracket. You won’t be able to install this kit without it. I wish that was more clearly stated on the product listing, as I almost didn’t order the wrench. But I’m glad I did. Now although the new stuff went on easy (provided you have the wrench) the old stock parts were a NIGHTMARE to remove. For the life of me I couldn’t get the original square post axle crankset off. I ended up buying a crank puller, but that didn’t work as the round peg couldn’t fit in the square hole to push the cranks off. It did however do a great job of pulling the threads out of the hole, oops. It took me a solid 2 days to get the cranks off and I ended up using an angle grinder to just cut them off. Thankfully the frame wasn’t damaged in the process. Your luck here may vary - and it’d probably be a lot faster and less stressful to take the bike to an expert technician and just have the old parts taken off for you if you get stuck. All and all I couldn’t be happier with this new crankset.

### ⭐⭐⭐⭐⭐ Nice Value Upgrade
*by J***L on August 30, 2020*

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. You can find my unboxing of this set on the youtube user Quadsmack
