These are great. I don't like that it comes with a 3mm chain ring when I needed a 1mm chain ring. With the cranks look awesome the bearings are smooth it is a work of art I'm giving it a five

The bottom bracket and axle adhere to the (Shimano) Hollowtech II standard, while the chainring is based on the SRAM GXP. This works, as both are compatible with other products of the same standard, but it's a strange choice. The teeth on the chainring *appear* to be optimal for SRAM chains (Bucklos website didn't have exact specs), so there's consistency with the chainring at least.I measured the chainline after installing it on a 2022 Spec'd Rockhopper and found it to be 55mm. This is limiting, as the chain is straight when on the third smallest sprocket (10s Deore) and very bent when on the largest sprocket; this will lead to premature chain wear and greater potential to break chains. As such, I would not install this on any QR setups. It will be compatible with *some* Boost setups (more like 12s). It should be fine with Superboost, but I doubt anyone sendy enough to use that wider standard would trust these cranks. Worse, the chainring is already at the maximum -6mm offset, so decreasing the chainline isn't possible.TLDR: They're nice enough cranks, but the wide chainline greatly limits the compatibility. The mix of standards needlessly makes servicing more challenging.

These are very nice crankarms for the money, as far as I can tell. I can't speak for the bottom bracket it actually includes quite yet since I already have my own bracket, but it also seems very smooth as well.The crankarms themselves are very light and seem very strong, and should last a long time.

This is a stout piece of cnc work. Very well made and feels extremely strong. Looks really nice and was super easy to install with the included bottom bracket. Works great on my Cadex vintage mountain bike. Tremendous value for the money.

After a month off riding I noticed that the non driveside crankarm bent after riding a local mtb trail. I should have just bought a brand name crankset in the first place for not that much more money.

This let me turn my commuter bike into a 1x set up with ease. I was also able to switch to a crank length that works better for me. The 170 cranks make a huge difference in how comfortable I am on the bike and let me lift the seat to a better height, leaving me at a better angle to the handlebars and cranks. I was very skeptical that this would make a difference but wow does it.These installed easily and the included spacers do an okay job, but I'm going to look into getting some aluminum spacers because I just don't trust the plastic.

so got this because I don't like the way that the square tapered crank on my bike kept working it's way loose constantly and thought that I would try something that is lighter in weight and smoother pedaling. This is both, and I would suspect that the bottom bracket on this is of much better quality than what came on the bike. I m happy with it, and with the weight and smoothness of the bearings and crank in general. I am not sure on the sturdiness of the attachment method on the cog to the crank. It screws onto the crank after fitting the cog onto it via a toothed fitting. The screws look pretty light duty to me and while i have not had them fail or anything, I am just not convinced that they will be tough enough to last. This is not a knock to this particular crank set so much as it is to the type of fitting method that is used. I will come back in six months and re-evaluate my trust level after a 1000 miles or so of trails.
