Strengths:    Strong, stim, light, good looks, easy to maintain.

Weaknesses:    Periodically comes loose, annoying use of Imperial bolt size (minor complaint - it is only one extra allen key to carry after all). BBs for use with this crank don't have a lot of protection against water.

Bottom Line:   
Fantastic crank. Light and strong, perfect for freeriding where you want the best uphill and downhill performance. I think I've solved the problem of the cranks coming loose - don't put too many spacers between the BB and crank to increase spline contact.

Date Reviewed: March 18, 2007

Strengths:    As all have said : stiff, strong, beautifull, alignement possibility, USA made, possibility to have spare or repair pieces easily, options on the length of the spindles and of the crankarms, they don't make any noise with both the crankarms or the bearing if you install and screw them correctly. Easy removable if you use the correct tools.

Weaknesses:    For some, the weight, but not for me. The spider : it's nice, but it's hard to obtain the shims and very long bolts if you ride with 3 chainrings (Profile doesn't supply long bolts and shims to fit to theyr spider).

Bottom Line:   
As I'm an Old School BMX rider and MTBiker, I've allways had a great satisfaction to can add BMX strong components on my MTB. I've 6 Profile cranks as well on my Old School BMX bikes, New School BMX and MTB. They are very strong and durable cranks. Profile Racing is a pioneer and still there, approximately 30 years after their debut in BMX. Their cranks are made, for the MTB case, for the rider who wants a strong crank and not searching for the ultimate lightweight bike. For myself, my riding type is XC, Hard XC, All Mountain, single trails with uphill and downhill adn little jumps here and there.

Strengths:    Everything. They light (for what they are.), they stiff, they last long, they usally never break. Nothing is better.

Weaknesses:    They rust. And o man they do. Chrome wears over the years. but hell, you couldnt use any other crank arm for as long. They are over priced. Euro bb's shouldnt be as much as they are but o well.

Bottom Line:   
Nothing is better. Ive raced bmx for 7 years of the profile racing arms. Run them on my dh mtb also. wouldnt run a bike without them they are that good. dont worry about the additional weight as its really not that much. If you all into weight and ride smooth get a ti spindle and the crankset as a whole will drop down quite a bit in weight. Just dont be doing downhillin or dirt jumpin on a ti spindle or ya will end up snappin it. us pride baby. Check their other products. Ill support these guys til I die. They that true.

Strengths:    Super strong, super stiff, light enough for that type of strength. Honestly the best cranks on the market.

Weaknesses:    NONE.

Bottom Line:   
The Best. Some reviews state fused arms to spindle; blame it on the installer. Some reviews state low bearing life; blame it on the installer. Installation is crucial to the performance of these cranks. Even good do-it-yourself mechanics should have these installed by a pro. I have 3 sets of these cranks (1 BMX, 2 mountain bikes). One set I've had for over 15 years! Original bearings! 14 years of BMX racing, trail jumping and just plain ABUSE! Still straight, still smooth, still quiet, still the best.

Date Reviewed: November 6, 2006

Strengths:    power transfer, custom lengths, durability, low maintenance, interchangeability, longevity. Price, compared to others for 180mm length, the lifetime warranty makes this crank a give away

Weaknesses:    get a euro BB with an adjustable cup. small parts expensive, M10x1.0 bolts? Q factor, needs offset spider, tough to get good Q and keep big rings off chainstay. file inside of pedal mount to taper away from chainstay for better Q, use small rings

Bottom Line:   
For cross country too. Last Sunday I was 200+ pounds going up hill like on a tow rope, riding partners astonished. Went from 177 (labeled 180!) adventure components nomad to 185mm profile BB and ti spindle. I knew the AC's were flexing. Finally a crank my legs can stretch out on. Weight penalty (small!) is erased by efficiency. To use this for cross country lost the inner chainring on a 5.75 spindle, 68mm euro BB. 29 inner, 42 outer, 2x9 style on a 94 bcd profile spider.

Date Reviewed: June 16, 2006

Strengths:    YOU CAN"T BREAK EM! Compared to these, everything seems to flex, yes- everything. I can't imagine a stronger crank... Ran original bearings since the EIGHTIES...They don't make them like that anymore! Really!

Weaknesses:    After years of two wheel flat lands from 8 feet plus, they shifted on the spindle (spline to spline) They are fused together. I even tried a press, and they are still stuck on a broken frame!

Bottom Line:   
Best crank in regard to stiffness...I can't imagine anything better for me! You may not know what your missing! Get a pair, but dear God $250...when are companies going to learn? If they were cheaper and more available everyone heavy and hard would run them!

Date Reviewed: June 3, 2006

Strengths:    Stiff, Strong, Style,lenght options,alignment...

Weaknesses:    BB Bearings don't last long. After 4 months mine where trashed. Note I do ride over 200miles per week in the all weather conditions.

Bottom Line:   
These cranks allowed my move the chain ring closer to the frame which meant I could use the big ring up front more often (reduced chain angle). With the long arms I could use a bigger gear, climb MUCH easier, top speed is higher, RPMS are the same 100-130rpms (highest I hit was 135 during an interval session don't believe that crap about long cranks=low rpms), Can use more of my hammstring muscle thus keeping power on tap for a long period of time resulting a smoother ride.

The big test was at the Mass Blue Hill Ski area. With the wet rocks and very very loose gravel (I still had my 60mm wide Schwable slicks on)the cranks allowed me to keep a steady power and torque out put so the tire stayed in contact with the ground, then there the Penn National Park where is was technical and dusty. Again the the cranks allowed me increase the torque quickly with out having shift up or down too much. Need to get over a big rock just push or pull on the pedal a little harder and the big just road over it.

This is the bomb. Next I am going for some 230's!!!!!

See ya, actually you;ll see me blasting pass you:)

Submitted by Zanetti a Cross Country Rider from Atlanta, GA

Date Reviewed: October 12, 2005

Strengths:    Very stiff and strong. Adjustable chainline. All standard crank lengths available - even custom lengths. Allows choice of 110/74 and 94/58 spiders or use of single BMX chainwheel. Same basic design for 25+ years - individual replacement parts are widely available. Cro-Mo arms will put up with untold levels of punishment -- they'll laugh off a mishap, like a loose pedal, that would kill an aluminum arm in a matter of seconds.

Weaknesses:    The BB must be shimmed properly for decent service life of the bearings. The provided spacers don't account for small manufacturing tolerances of mass produced BB shells. Profile needs to provide an assortment of steel shims to accomodate such differences. Two spacers, one for 68mm, and one for 73mm shells just doesn't cut it.
Luckily, I have access to a machine shop, and I was able to fabricate perfect length spacers for my setup. Almost five years have passed and I'm still on my original set of bearings.


Bottom Line:   
Weight and BB setup issues aside, they're one of the best cranks available.

The weight issue is a little overblown. Here's an example:

XTR M900 arms,175mm: 532g
UN-72 BB 68x107: 252g
Total-----------> 784g

Profile CR-MO arms,175mm:560g
BB with Ti spindle: 311g
110/74 Spider: 90g
Total-----------> 961g

177 grams difference. A full 16oz water bottle weighs about 543 grams. My sleek Ti hardtail that weighed 22 lbs even with standard cranks now weighs 22.4 lbs with the profiles installed. *BFD*
Chainring/mount bolt weight is not included since they'd be installed regardless of cranks used. Is 177 grams extra weight worth it for a lifetime of worry free performance? I think so.

Strengths:    on my bmx: everything, how un able to bend they can be, life time warrenty.. had mine for 6 years and they aint bent yet from plenty of crashes, drop offs, throwing my bike all over the show, plenty of temper moments.. i've had the same bearing cups and axle in 2, cups might have grinds on and the cranks maybe dented but they are still going stong and still give me confindence.

Weaknesses:    none found so far.

Bottom Line:   
there aint any other crank out there that i know can beat the value for money,the fact that you know you have cranks on that aint gonna snap off..

If you concidering buying some new cranks. without a doubt.. profile everytime... dont concider anything else.

Strengths:    Strong as hell. Not the lightest but you have to sacrifice one thing for another.

Weaknesses:    Bearings wear out eventually.

Bottom Line:   
I haven't ordered my MTB cranks yet. I am going off my Profiles. I race nationally, 5th in my Midwest region in 13 Expert. Anyways, my BMX cranks are a godsend. At 200 lbs, it is easy to destroy cheap cranks. I rounded off a set of Black Widow Alum arms. Now I wil never turn back. Bearings? Well, I haven't replaced mine in a long time but they are beginning to click a little bit. No bike product is invincible because there is always someone out there who rides harder than you. I wil come back in a few weeks with a report on the MTB set. I will also be ordering a new cassette and brake levers.

Date Reviewed: May 16, 2003

Strengths:    Crank arms and spindle are built like a tank; weight says it all. Chain ring and guard is a piece of art.

Weaknesses:    The bearings are the weakest out there, so they do need replacing every now and then, so if any signs of crank seizeures, get em replaced or you'll dammage the bottom bracket with it.
The chain ring and guard is a piece of art, because its aluminium its going to wear out depending how much riding you do, and its going to be a really costly replacement.


Bottom Line:   
The crank arms will out last your life, but the bearings and Profile chain ring won't out last your tires, maybe due to poor design so they do need a bit of carefull attention especially if conditions are wet and muddy.
Therefore if you like to tinker like a mechanic and ride like a maniac with a fat wallet - you decide.

Bottom Line:   
These cranks are stronger and stiffer than any aluminum crankset. Sure they might be a little heavy but they don't ever creak and they are easy to adjust and accomodate chain guide systems without a hitch.
Anyone that has anything bad to say about these cranks is an idiot and they probabably don't even ride.

Strengths:    Strength...yeah. These are the stiffest crankarms I have ever used. They were also extremely easy to install, just make sure you have a 5.5mm hex wrench handy. They work well with multiple chainrings...I have a bash guard, a 39 tooth, and a 28 tooth ring, and it shifts great.

Weaknesses:    Lack of technical support from Profile Racing. I bought them and was just hoping they'd fit. I also bought an install/remove tool I didn't need b/c one comes with the cranks.

Bottom Line:   
These are great for big riders, rough riders, downhillers, dual-slalom riders, guys who jump, guys who do drop-offs, and guys who wreck a lot. The best upgrade I have ever made.
