CYSKY Mountain Bike Crank Arm Set - Perfect for Cycling Enthusiasts

Jack MurrayJack Murray: 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...

RogerRoger: 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.

DNDN: 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,...

Ken: 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...

MBMB: 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.
