Review: Nice Value Upgrade - 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 desertcart 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
Review: Great crankset for the price - After reading the reviews, decided go with this iXF crankset for my Diamondback Overdrive 29er, and it was the best decision I made for it. I had to change out my original square-tapered BB anyways since it was knocking while riding and was loose feeling, and since I never use my front derailleur I decided on going with a cleaner 1x setup. The install was very easy & straight forward. Lots of good install videos out there to follow. Just make sure you're installing everything on a clean surface and use grease sparingly on the necessary areas. After installing everything and going out on quite a few rides already, I can say this crankset is definitely much stronger and can hold up to some good jumps that I've already put it through (with 230 lbs coming down hard on it when I'm standing on the pedals). Really good setup, especially for the price. If you’re building a budget 1x setup, this crankset is a great way to upgrade your bike without spending a lot. For reference, I'm using a JGbike Elite chainring, so my overall conversion cost was around $80 that included the Shimano BB I also purchased. I will admit that the BB that came with the kit looked fine, but I decided to upgrade that area and spend a few bucks more to get a Shimano hollowtech BB, and kept the included one as a spare. I can't say anything good or bad about the included BB since I didn't use it, but I did see a few reviews from people saying they started to experience some problems over time with it, so I decided to spend a little bit more on a known quality part in that area of my bike. Nothing against the crankset kit, just a personal decision.

## Questions & Answers

**Q: Will this work on my Trek 820 21 speed?**
A: This will work for your trek 820 as it uses a euro bb

**Q: do these come in a 165mm crack arms**
A: 170mm crack arms only

**Q: Inner black plastic sleeve shorter than when I bought this same item a year ago, barely reaches. Is this part necessary for proper function?**
A: Installing the sleeve is optional. It’s supposed to keep dirt and water off the spindle but it touches the spindle which introduces more friction into the system. Just clean and re-grease the spindle once a year if you don’t use the plastic sleeve. You don’t need to unscrew the bottom bracket to do this. Just loosen the pinch bolts on the crank and pull the spindle and right crank out of the bike.

**Q: What is the crank screw for?**
A: there is a cap that goes on one side

### ⭐⭐⭐⭐⭐ Excellent Cranks for a Great Price.
*by R***R on December 15, 2020*

I bought these cranks as I saw them on youtube with great reviews and information. I used these cranks for a retro rebuild for a friend's bike. We went from a 3x9 gear set up to a 1x9. Everything mounted up just like any high quality cranks. The bottom bracket that came with the cranks were nice and smooth. The cranks are of high quality and should last for a long time as my friend's bike will be ridden by his daughter on fire road trails and street riding. I received the cranks in 2 days and was quite impressed with the quality build of them. Highly recommended if you're looking for a crank / bottom bracket set for your bike.
