Strengths:    Cheap. Strong. ISIS is a solid BB system. Look good in either colour.

Weaknesses:    ISIS is a heavy system.

Bottom Line:   
I've got two sets of the Blaze. One silver, one black. Looks are irrelevant to me, only price/performance, but if you care, the blaze looks good. I like the silver better - despite almost always preferring black in everything else - inc my frames/forks/grips/helmet/levers/DLs/gloves/shorts/shades etc etc. So the silver must be nice. Doesn't show up scratches like the black either. Anyway, vanity aside, let's get to the meat and potatos.
I weigh 180lbs. I live in the Rockies and ride AM with fast rough rocky downhills. These cranks have had no problems at all in 3 seasons. Make sure you tighten them fully and there is no lateral movement of your chainrings if you use a decent BB for your application. I put my 3yo set of Blazes from the hardtail onto a project beater using the Giga Pipe SL BB. I liked them enough for the time I've had them, that at sub $50, I got a new set for the hardtail. I run that on a Giga Pipe DH BB and the combo is v solid for AM riding even with my 180lbs on rocky trails - on a hardtail.
No problems. Trushift works well. Teeth are a decent finish. 7075 T6 ring is reasonably durable. If you shift under heavy load (you shouldn't) you may want to file the odd tooth/pin burr each season to keep things perfect.
I can't give these 5* overall as systems like the Stylo are much lighter for not that much more total system price. Stylos w GXP BB can be had for $140 delivered versus $100 delivered for Blaze + BB. However, these are great, smooth shifting, solid cranks for those on a budget. Def 5* value. If you see any flex, it's not the crankset's fault. It's just not tightened properly. You need to pull your cranks, grease the interface and your bolts and tighten properly. Don't strip the bolts, but don't be shy either. USe a long wrench. You'll feel it when the cranks are seated as there will suddenly be a big change in the force required to turn the bolt. It'll suddenly stop turning, but you must grease the treads and faces of the bolts. I've not had any issue w Truvativ products so far. I have four sets of cranks, five BBs (2 Powerspline, 2 ISIS and 1 GXP), a seatpost, a stem. Like this brand (owned by SRAM) and the Blaze is one of the reasons why.

Strengths:    Solid crank,no bent rings so far, light.

Weaknesses:    none.

Bottom Line:   
The Crank itself is flawless. I used to have the flow but it wasnt compatible with a sealed BB so I bought this one. The only downfall is the stupid BB that truvativ supplied is rubbing against the crank arm causing resistance and a bad squeak. Ill have to take it in soon.

Strengths:    Got two good years out of middle ring before bending

Weaknesses:    Bent middle ring, but I've bent Shimano LX also (multiple times). Bent big ring and I use a rock ring too.

Bottom Line:   
Decent cranks that came with the bike. More durable than the multiple bending LX's. Don't creak (LX's always did on C'dale Superv1000)

Date Reviewed: September 2, 2008

Strengths:    Cheap, came with bike.

Weaknesses:    Very weak, not durable.

Bottom Line:   
These cranks came on my bike and within the first month of use had already bent. I weigh about 160lbs and do a mix of decent climbing and light freeriding. In the first 2 weeks the middle chainring had already bent and I could see the cranks flex on climbs. Now the cranks themselves are bent. Only use these if they come on your bike and you dont plan on doing any real climbing.

crank arms are pretty strong


Weaknesses:    anodizing rubs off
bent my middle ring badly and the outside ring became a rock ring


Bottom Line:   
used these cranks for a year and a half now, ive had to replace my rings with FSA's because of what i mentioned above. these cranks are being moved to my singlespeed as i am now getting XTR's and they will continue to be thrashed even more dirtjumping. a great crankset for starting out

Strengths:    the cranks are bomb proof

Weaknesses:    a little heavy and the paint wears off from rubbing after a season

Bottom Line:   
the bottom line is these crank arms and the chainrings it comes with are bye far the toughest components on my bike, i say that because i'm not bye the longest stretch of the imagination nice to my bike, i've bent my 30.0mm thompson seat post, i'm on my second pair of axiom handlebars, original ones snapped, broke a shimmano xt rear dérailleur in half, lost my 9th gear 12 tooth sram out in ames nowell state park, dont ask me how but it just snapped and fell off, and i have gone through 3 sets of pedals due to braking (not bending) them on rocks, all that was the summer of 2007 , and through it all my
Truvativ Blaze crank arms and cainrings are still holding strong, and to all the people giving them a negative review read the owners manual before installing them, and make sure your BB isn't thrashed, give me a pm in the forum and i'll show you some pics and a video that will change your mind my s/n is splattered, and as far as bending NO F#%$&^% WAY

Strengths:    only about its lightness.

Weaknesses:    Using them for 4-5 month caused their bending. my weight is about 156 pounds and I install them propertly, tight it well. But acurate street riding without any drops at all causes it bend. Note that Truvativ positioning them as AM crankset

Bottom Line:   
cheap but not strong system. If you by it tighten it as hard as you can.

Date Reviewed: August 27, 2007

Strengths:    it hasn't broken yet, which is good. that's about it

Weaknesses:    -really noisy, don't know what it is and it can never seem to be fixed( i don't know if it's the BB or what, which is a truvativ powerspline)
-not really smooth feeling


Bottom Line:   
It isn't a particularily good crankset, but i guess it's pretty good for being fairly cheap. I haven't broken mine yet (got it in '05), even though i've used it for everything from crosscountry to some light downhill stuff.
It's been pretty good though considering that on the 2005 truvativ website, it was under the "comfort" section...
If you don't ride to hard i would reccoment it, but if you ride more than light trails save up for something better, because it will start to get very annoying.

Weaknesses:    i have this crank for a week and already don't like it. aside from the fact that I think I have now broken it, when I first started using is, it wasn't stiff emough for me to pedal hard up hills. It bends so much that my chain rups on my deraileur.

Bottom Line:   
Choose something stiffer and lighter.Its worth the money for someone starting out
