The TruVativ Noir Carbon XC crankset is the lightest and most refined cross-country crankset in the Truvativ lineup, featuring a lightweight forged AL-66 Alloy spine wrapped in a unidirectional graphite layer for strength and style.

Strengths: Light. Colour?
Weaknesses: Completely unreliable. The teeth on the chainring wore out after about 20 rides. I had these on my race bike which I only used for pre-rides and races. It was installed with a brand new rear derailleur, cassette and chain and should have lasted at least a couple of seasons. Alas, in one of the biggest races of the year, my chain began skipping even under minimal tension and I couldn't even pedal up a curb without a horrific grinding and skipping. Frustrating! Maybe I got a dud, but this is only the latest in bad experiences with SRAM products as of late. Think I'll stick with SHimano.
Bottom Line:
I can't endorse this product. Go a bit heavier and buy something reliable, like Shimano XT.

Strengths: Strong, lightweight, different colors are awesome.
Weaknesses: I don't know if I can call this a weakness but it was tough to figure out the correct spacers for my bike, but it's prolly the fault of my bottom bracket design.
Bottom Line:
I've hit multiple rocks/roots/ etc with this crankset going full speed and i'm 250+ lbs. This crankset is strong as hell for carbon. I've got a few scratches on the bottom of the cranks but there is no doubt in my mind that these cranks are strong as sh*t. The rings have held up just fine and I love showing off my carbon parts to other riders on the trails. BUY this crankset!!

Strengths: Stiff, Not overly flashy.
Weaknesses: Scuffs, creaks.
Bottom Line:
These are good cranks, and from what I've read probably the best value out there. However, they started to creak bad after a 30 miler in the rain last year. Thinking the BB was bad, I pulled everything apart and their was no issue, so I greased everything up and reassembled - even removed and greased the splines on my pedals. The next ride it seemed fine for a while, but the creaking started again...bad. What a pain on a full suspension bike, since at this point I'm thinking it might not be the cranks at all. Things like this can really destroy the pleasure of a ride. I eventually greased the bolts on the crank rings, and found one to be really over torqued. This shut them right up. I hope this helps anyone else experiencing a similar issue with these cranks. I'll usually have to do this every 100 miles or so, but I tend to ride no matter what the weather/trail conditions are like. Performance wise this issue was minor, but creaks and rattles do not instill the confidence that is needed to make it through your ride.

Strengths: Strong, stiff, good looks
Weaknesses: Cranks scuff easily...buy crankskins if you want to keep them looking good
Bottom Line:
Good looking, stiff carbon crank. Not as light weight as other carbon cranks, but it is also very strong. Was easily mounted up and does not creak. Love the red anodized small ring and red branding on the cranks. As I mentioned earlier and have seen in other posts, you'll want to invest in some protective crankskin decals to keep the arms from scuffing from heel rub. If you not in a hurry look on Ebay or Craigslist for a good used pair.

Strengths: Solid, light and they look great.
Weaknesses: Scuff to no end!
Bottom Line:
Seem to be available all day long on ebay at or around the 200 dollar mark, can't beat that. For me, pretty doesn't factor into my decision, performance all the way. Stiff and strong, no complaints. If you have heal rub, you will age these cranks in less than 10 rides. My bro used my bike in wet sandy conditions and his feet scuffed the cranks way bad. My only beef with that is resale value. Otherwise, score them on ebay.

Strengths: Looks pretty
Weaknesses: Crank arm failed (carbon has seperated from aluminium spline) GXP bottom bracket poorly sealed
Bottom Line:
Brought second hand but in good condition. After one year non-drive side carbon crank arm has seperated from aluminium spline that binds bottom bracket axel allowing a few degrees rotation (so it is stuffed). Can't say what happened to crank before I got it but cross crountry use only from me over last year. I feel top price cranks shouldn't fail at the carbon aluminium interface. GXP bottom bracket is poorly sealed and can not be interchanged with other brands (unlike raceface, shimano which use a common sizing with lots of aftermarket alternatives). No product support as it is not possible to contact SRAM/Truvativ directly (and LBS says can not help). Recomend avoiding this product.

Strengths: Light, strong, looks good.
Weaknesses: BB wear does seem a little easy. Older models loosen easy.
Bottom Line:
Initially, the crankarm would fall off. Been using my bike shop for years and trust their knowledge; however, two of the three or four times this happened was during a race. One of the times I was into my last lap in 2nd closing in on first. Not cool.
Now for the good news. If you just make sure like the others say that this crankset is torqued at the correct specs, it will bring you joy.
Last but not least, today, after 2 years of HARDCORE use, there was some creak noise that continued even after a BB replacement. My shop called SRAM and after learning I had it for 2 years asked no more questions and is sending me a brand new Truvativ Noir crankset.

Strengths: This review is for: 2009 Redwin Noir 3.3 crank
-Stiffer than any crank I've ever used
-Nickel Teflon finish looks durable and helps shift more smootly
-pretty light (805g w/GXP BB)
-Two words BLING BLING
Weaknesses: None. Expensive but Truvativ really delivered a good product.
Bottom Line:
If you have the $$$ to buy these as an upgrade to any other crank you may be running you will not be dissapointed. They proform well on rough terrain and are extra stiff and light. Not to mention the BLING BLING it adds to your ride

Strengths: - stiff
- very light (800g with BB on my kitchen scale)
- not too expensive
- durable
- look nice on the bike
- switching gears works flawlessly
Weaknesses: - the BBs tend ro wear a bit fast I think
Bottom Line:
I use them on both my bikes and have had no real issues until now. When mounting them just be sure to thoroughly tighten the screw and it will work. When riding them AM I found they could even take quite a fair beating from rocks. Spare chainrings are not too expensive. Only an upgrade for the BBs might make sense in my eyes. I´ve ordered some Hope BBs, but haven´t tried them out yet. Any way I think they´re a good alternative to XTR cranks.

Strengths: Stiff, Light, and they look sharp
Weaknesses: Actually require a torque wrench to install. Calibrated Hand Torque WILL NOT work on these.
Bottom Line:
About the same wieght as XTR cranks for 150-250 bones less. They look really, really nice, and have done just fine bouncing off rocks.
One thing to keep in mind is that these must be torques to the appropriate spec. Also, 40 Ft Lbs of torque is a lot more than you would imagine. I would not suggest winging it. I read a lot of complaints about people have last years version loosen up on them. If you torque them to spec you will not have this issue. If you don't set them up correctly and experince issue son the trail ther eis no way you are going to get that sort out.
Bottom line: Great price, look awesome, and light. Set them up right, and then you can forget about them and enjoy the ride.

Strengths: Looks, stiff, light, shift -- all good.
Weaknesses: None so far.
Bottom Line:
I was skeptical about Truvativ bottom brackets as a friend had one explode after a couple of months, but so far, the Noir’s have worked perfectly. I was looking for a good deal on some cranks as my FSA Carbon cranks had to go back to the manufacturer, due to pedal inserts breaking loose. I found these for about $350 on-line which is cheaper than many aluminum cranks. Be careful to install them per the unusual directions (requires tightening and loosening several times) and be sure the crank arm bolt has the proper torque. I recommend continuing to check the crank bolt torque after every ride for the first week or so as they set-in (mine tightened about a quarter to a half turn after the first few rides), then it is all good. Highly recommended for the cross-country rider/racer, do not hesitate -- buy them.

Buy these...they are light just as they say they are. Get them from Chain Reaction. The shipping is free and it comes with the BB unlike many other places that are still more $$.

Strengths: Stiffness, Build Quality, Ease of installation, Looks!
Weaknesses: I am not crazy about having an aluminum bolt holding the cranks together. But that is more of my mental issue than a fact. The aluminum bolt is probably more than strong enough. This does not affect my rating because it is irrelevant, just noted.
Bottom Line:
I am a rider that weighs under 170 and rides between moderate and aggressive. I was torn between going with an XTR crank and these. I am very glad I went with the Noir. I can't tell you how much notably stiffer they are than the Hollowtech series shimano produces. I have to say it was a chance well taken. I also like that fact they come with aluminum chainrings, not some abnormal material that is going to wear out in one season. Note that these cranks don't come with a BB. So if you plan to order them be sure to pair it with the Giga X Pipe Team BB.
