Best crankset I could find for a 122.5mm BB
I upgraded to this crankset because the original no-name crank that came on by bike had gears that were out of true. I stayed true to my original gearing and got the 28-38-48T set, and went with the longer 175mm crank arms, and I'm glad I did.

I considered going with the next level up the "Shimanao Alivio" but I would have had to change my BB to make that work. This crankset matched my 122.5mm BB perfectly, in fact, to my knowledge this is the best crank you can buy that fits a square taper 122.5mm BB.

I immediately noticed the following improvements with this crank: Shifting has become much smother. The gears are nice and straight so adjusting my front derailleur is no longer an impossible task. Compared to my old crank this one is extremely light, at least a pound if not two lighter. The crank looks very nice.

Great replacement on a budget
My son bent all three rings on his stock specialized entry level mtn bike. I wanted a budget friendly replacement as he had outgrown the bike and I was likely to sell it. Out of the box, these appeared to be better constructed than what was on the bike, specifically in the rings and supports. Once installed, we have had no issues with shifting or flex.

Good upgrade for older bike
I got this to put on a 90s Montague folder, and it worked fine.
It's not light or stylish, but it's way better than the 20-year-old crap that was on there before.

Does this set come with both crank arms?
Adam E on Jun 29, 2017
BEST ANSWER: Yes. I have never heard of someone selling a crankset that required paying more for the other crank arm.
Does this include the crank bolt?
m g on Jul 21, 2017
BEST ANSWER: Yes; I received two bolts w/the M361 Square taper crank.
Would it work just fine with 10 speed chain ?

BEST ANSWER: ** I added chainring spacers to move the chainring (in the middle position) out a bit to improve chainline.
I have the M351 crankset. Is there any difference between the two? Can both be converted to 1x drive?
Travis H on Aug 7, 2017
BEST ANSWER: Both cranksets are very similar, the M361 does not have a bash guard and maybe lighter weight marginally. Both can be converted to 1x, but you would beed a chain keeper and a clutch style rear derailleur to avoid dropped chains.
Is the inside face of the inner chain ring flush or are there flanges that project inward?
PaulN on Jul 7, 2017
BEST ANSWER: Both sides fo the inner chainring (28T on the one I have) are flush with no ramps or flanges. The middle and outer chainrings are the ones that have the hyperdrive ramps.
Does this set use the standard 104/64 mm bolt circle diameter?
LimpSquiggy on Dec 30, 2016
BEST ANSWER: Yes it does...if your BB is not 122.5mm, you will need that as well. 113mm is too short.
Is it possible to convert this crankset to a 1x drive train?

Thanks
A shopper on Aug 6, 2017
BEST ANSWER: Yep. Just dont use your front derailleur.
What size BB do I need for this product?
George on Jul 8, 2016
BEST ANSWER: 68x122.5 fit mine perfectly.
Are the chainrings bolted or riveted together?
OverTheBars on Apr 13, 2016
BEST ANSWER: Bolted. Thanks!
