CYSKY Bike Crank Arm Set Mountain Bike Crank Arm Set 170mm 104 BCD with Bottom Bracket Kit and Chainring Bolts for MTB BMX Road Bicyle, Compatible with Shimano, FSA, Gaint (Black/Red)

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

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.

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.

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).

I bought a used trek Marlin 7 that used a 3x9 drive train but since the front gears were severely mangled I decided to convert to a 1x9 with this system. The bottom bracket fit perfectly and the installation of this crankset was fairly easy. The hardest part of the installation was removing my old crankset which requires a bottom bracket tool and crank puller. A chain guide is essential with a 1x9 system if you ride hard but if you take it easy you may be able to get away without one if your chain is properly sized. If you are switching to a 1x9 I would recommend getting a 30 tooth front chainring. You lose the super easy gears but it's worth the weight savings and the simplicity of the 1x system which is essential for mountain biking.
