Strength:

Strong, Stiff, Cheap. Shifts great. Light enough

Weakness:

None really. I guess you might not impress any bike snobs, but that's about it.

Everything you want in a crank. Shifts better than the XT I had on before it. I didn't think a plastic bash guard would hold up that well but this thing can take some abuse. My cranks have a tendency to develop creaks, but after three years this thing is still quiet. I hope they keep making these the same way, I couldn't be happier.

Strength:

STRONG, light, really nice/durable finish, easy install & adjustment.

Weakness:

NONE!

Shimano says this crankset is 100% stronger than XT. It seems plenty strong to me - I don't notice ANY flex or weakness. It's very light - especially the BB & arms. I'm surprised by how well the plastic bashring holds up to the rocks I've been hitting, but it does, so it's fine by me. It shifted very smoothly when I had a front der, but have since switched to a 1 x 9 set up, via chain standwich, which works very well. The 22/36 set up just didn't work for me; so now I just run a 32T, which is perfect for the riding I do - some AM, some XC racing. This crankset really has been flawless; which is especially noticeable b/c everything else on my bike has problems ;-)

Great product. Amazing value.

Strength:

Stiff as all get up
Chain rings shift like BUTTA

Weakness:

None really. Bashguard is heavy and could be removed, but if you're riding such that you need a bash, you're prolly not counting grams...

KICK-ASS CRANKSET! When paired with the SLX FD, this thing shifts in spite of my worn-down drive train, misadjusted FD, and other general installation mistakes. Shifting is super smooth and the ratios work out perfectly. Stay in the 22 when climbing (or as a 36T bailout) and then switch to the 36T on the way down. Gears are more useful than the 26-39 setup from Sram. Chainrings are heavy (steel vs AL) but the shifting ramps are present on both the 22T and 36T and the combination is flawless.

Strength:

makes for a good chainline, good ratios -run it on 2x9 race rig without bashguard and stay most of your time in 36t; great clearance compared to 44t triple

Weakness:

a bit heavier with bashguard (but bashguard is realy beafy fo the those one that want it).. can be removed and save 200g

use either with bashgaurd (a bit extra weight) or remove the bashguard (200 gramms) and get lightweight double crankset (about 800 gramms)... run that on your bike for improved chainline and with 22/36 I can spend 95% in big 36t chainring and shift just on cassette. works great.

Strength:

Strong, smooth shifting, lightweight compared to my old triple

Weakness:

expensive, bash guard a little cheesy looking. Need to spend time tweaking your front derailleur to get the shifting just right.

A good upgrade from a triple for trail riders. You have to get used to the new ratios (22 36t)but you quickly find the right gear after a few rides. Chain line is much better and the added ground clearance and bash protection is great.

Strength:

Bombproof. The chainrings have only lost a bit of the anodising after 6 very gritty months. The BB is spinning as sweet as the day it was fitted. Stiffer than a very stiff thing from stiff town.

Weakness:

Could be lighter its not the heaviest Twin and Bash out there but the bash ring is very heavy.

If I ever break any part of this set I wont be worrying because the crash will certainly have killed me. I will never go back to a triple ring set on my MTB

Strength:

Stiff, not light, but its not a porker either. The bashring does its jobs.

These are a great crank for the price and they get the job done. I have had zero issues with them and the bottom bracket.

Strength:

Stiff , looks great once you get rid of the hideous bashring, Cheap, solid construction with steel pedal inserts . If i ever break this i will buy another , and i can see that happening.

Weakness:

None

Cant gett a better crank for anywhere near the price, BB is crap as usual .... just change it when you get the cash . The money you have saved on this crank over the XT ot RF AM will buy you a hope ceramic BB . Ditch the 150g bashring for a light one and you have a crank the weight of an XT with twice the strength.

Weakness:

The Bashguard is heavy and dumb-looking

Really good crankset. BB is smooth. Crank is stiff. replaced the bashguard cause IMHO it looks dumb and irs eally pretty heavy. One thing to note - the triple chainring, besides not having pedal inserts is not the same crank as the double. If you look close at the spider, the double's is thicker and sturdier. My wife has the triple and its slightly more flexy.
