Description:What's black, has four arms and is stronger than steel? The Diabolus crank - simply the stiffest, strongest freeride cranks out there. We've taken the same design philosophy that created the award winning Diabolus stem and applied it to these cranks. The result: a high performance freeride/dh specific crankset that's not a boat anchor. If you're looking to go hard and fast, look no further than the Diabolus.

  • The new standard for freeride cranks, set by the original freeride crank designer
  • Built in our BC manufacturing facility
  • Forged and fully CNC machined from one of the strongest, most fatigue resistant aluminum alloys available
  • Oversized crank arms for unparalleled stiffness and strength
  • Beefed up chainring spider to withstand hard impacts
  • Removable granny ring spider for improved chainguide clearance
  • Patented I-LOCK reinforced pedal interface features a secured chromoly pedal thread insert that WON'T strip out or come loose.
  • heavy walled, heat treated CrMo spindle
  • Also available in ISIS Drive

    Built for: DH and Extreme Freeride
    Size: 165,170, 175mm
    Warranty: Lifetime
    Colours: Bad Ass Black and Shiny Silver

    Strengths:very strong!! I having been doing hard tail free riding and these have held up to some large drops with no issues.
    Weaknesses:on the expensive side
    Similar Products Used:lx, xt, saint
    Bike Setup:santacruz Chameleon, jucy 7, wtb fr wheels set, lx and sram running gear
    Bottom Line:I have heard all of these complaints about these and how hard they are to put on. Get tools!!! Thats all you need and the instructions. had my lead mech, at the shop I work at show me how to pt them on and if you use the wright tools and follow the included iknstructions then they will work perfectly. I any very content with the out come of these and they have no flex as others do!!! IF you do a lot of heavy riding then buy it and have a well know mech install them, don't try it your self with out proper tools.

    Strengths:I havent riden these cranks, but I think they must be VERY strong. I guess if you get them installed correctly then they will probably NEVER have problems.
    Weaknesses:There is one HUGH glairing problem with these cranks. Instalation. If you are going to have a shop install them and they can do it right, then you are pretty much good. But, if you are going to do it, or your shop is incompitent, then you are going to have a REALLY hard time. You have to put SO much torque into the cranks it is insane. I had to install 6 pairs of them last night. If you dont have 2 large breaker bars then you are really going to beat up your hands. Also, the quality is very suspect. Why when you install the crank on three of the same bike, do you need to use different spacers for the spindle? If every part is the same, the spacers should never change.
    Similar Products Used:Saint, XTR, XT. ALL these products are FAR better.
    Bike Setup:Haro thread 1 w/ saint crank.
    Bottom Line:Bottom line is this. If they somehow get installed right, they should be fine. If you have to install them, or take them off for some reason, I feel very sorry for you. I would NEVER put these on my bike. EVER!!! Not even for free. Worst install EVER!!! I will give them 2 chilis to be fair because they seem indistructable, but that is it. They need a maintanance rating. they would get a negative 5 chilis.

    Strengths:Strong, Stiff, looks good (does what it says on the tin)
    Weaknesses:BB not so strong because you cannot grease it.
    Similar Products Used:Shimiano Saints/Hone
    Bike Setup:Intense M3 DH bike
    Bottom Line:These cranks are uber strong, you will not break them, Raceface have machined them from billet aluminium to make them last for a life time. They also use a steel pedal thread insert (I-lock) brilliant idea! The only downside is the BB do not last as long as the cranks, they cannot be greased because they are closed cups!! I would recommend these to any freerider/Downhiller who destroys the trails! - Fit and forget parts, awesome -

    Strengths:Bombproof.

    These things are built like a tank. I've smashed em' off of rocks, boulders, curbs... geez - I need to get smoother... anyway, point being - they're still straight as an arrow. No bending or twisting. (Lots of scratches though)

    Zero Flex. The stiffest cranks I've ever had.
    Weaknesses:Weight. For a set of 165mm cranks they are about 1085g with the Diabolus BB and no chainrings.

    A similar set of SAINTS are about 1007g (only with BB and no chainrings)

    Due to the over-engineered design of these cranks to take maximum abuse, they're practically boat anchors in the world of MTB cranks, but - they'll never give out on you.
    Similar Products Used:Shimano XT, Truvativ Holzfeller
    Bike Setup:165mm cranks w/ 83mm BB shell on an 06' Iron Horse Sunday Factory... too much stuff to list, but it's definitely been pimped out.
    Bottom Line:Thought I'd mention - I'm about 5'10" and probably weigh about 175lbs. with helmet and armor...

    These cranks are bombproof. The norse god Thor could use one of these things as his mighty Hammer - it's completely ridiculous the amount of abuse they can take. If you can bend these things you're either dead or have bailed before letting your bike ghost-ride off a cliff.

    But to get this kind of strength you also get the weight to go with it. But to me, it's one less thing to worry about - I know these cranks will never bend, break, or twist. Race Face has done some great work on these with their CNC machines - they look pretty sweet. Think of these as the American counterpart to SAINT cranks.

    Duration Product Used:2 Years
    Strengths:Strong and sexy looking
    Weaknesses:Won't stay tight for very long, Turned purple after 1 season. Have developed "Play" at the top of each pedal stroke.
    Similar Products Used:Saint, Truvativ stuff, DMR
    Bottom Line:This is a pretty darn good crankset. They very strong and I haven't had any major failures yet. However, I am only able to keem them tight for a while, but they always seem to work their way loose after some time. I just put new threadlock on every 2 rides and carry plenty of tools to keep them happy. On a side note, since they come loose every so often the teeth in the crankarm that mesh with the ones on the spindle are starting to wear. This has created a slightly annoying movement at the top of every pedal stroke. Oh yeah, they are no longer black but a funky looking purple. Overall I am relatively happy, but I just wish they would stay tight, not turn puple, and stop clicking every pedal stroke. Not bad fot almost 3 seasons of use, but I don't think I will buy another set to replace my existing ones.

    Strengths:Stiff,strong,looks
    Weaknesses:bearings
    Similar Products Used:Saint,Race Face Turbine,XTR hollow II
    Bike Setup:Santa Cruz V10, Boxxer WC,
    Bottom Line:If you know how to set up a bike or have worked in a shop then you will have no problem with these cranks. You need to use the correct amount, and type of spacers which are provided. You can't "back off" the drive side fix bolt to adjust bearing preload, if you do, the crank will fall off, it's not rocket science. If you are a hack like some people sound like on this site, take it to a shop, don't badmouth products just cause you don't know what you are doing. If you want a warranty, then pay full price at a dealer and quit whining.

    These are stiff and strong cranks, they are a bit on the heavy side. They are not as simple to set up as saints and the bearing quality is not as good as shimano and some guys have had problems with that.

    I would by them again no questions asked.

    Weaknesses:expensive
    Similar Products Used:just shimano xt

    Bottom Line:I bought this off ebay used and put it on myself. At first I was disappointed in the amount of drag when I tried to rotate them. I ignored it and just rode it for 7 or 8 months. Then I took everything apart and cleaned it really good just to help prevent any problems. When I lubed everything and put it back together, it spun great and I still haven't had any problems with the bearings coming loose. I like this crank and would buy it again for any freeride bike that I built up.

    Weaknesses:drive side refuses to stay tight
    friction
    Similar Products Used:Truvativ, Shimano, you name it
    Bike Setup:Ellsworth Id, my favorite custom gruppo
    Bottom Line:Sorry, Race Face, this crank system just don't work.

    Following installation instructions EXACTLY results in a ridiculously high friction setup. But don't bother backing off on the torque, because the drive side will automatically fall off on its own! I have been dinking with this crankset for the better part of 1 year, and i am convinced that the Race Face drive side master bolt is just a flawed design. The drive side comes loose after 1-3 rides no matter what i've tried.

    Time to bite the bullet and buy good set of Stronglight cranks or XTR. I have no more patience for this Race Face sh!t.

    Value: rings and cranks are great, BB locking is unacceptable
    Overall: don't even bother to buy them unless you need replacement rings and the store has a blowout sale.

    Strengths:Strong as hell, slick looking, and nice pedal interface.
    Weaknesses:Anodizing turns purple almost immediately. It's not just a tint of purple, but nasty blotchy coloration. Serious spline issues too. See below.
    Similar Products Used:Nothing really.
    Bike Setup:KHS FR1500 with a 5" Marzocchi DJII, and nice DH component setup.
    Bottom Line:As said before, defective drive side crank to spindle splie interface. They were properly installed. Since I bought these off a buddy brand new, I can't file a true warranty claim with them. I'm still trying to get in contact with them about replacing them anyways. I don't have a problem with them or their products, but they did something wrong with these cranks. Idea was great with these cranks, but it looks like the splines were out of specifications...

    If there wasn't the spline problems, then they would have earned 5 chilli's from me, but it kinda ruins it for me when I can hardly ride them.

    Also, the spline problems did not develop until owning them for about 3 months, so keep an eye on them if you do buy them, or already own them. Don't lose your reciept.

    Bottom Line:I've had these cranks for about a year now, and enjoy them a lot. I've ridden them hard and taken them on and off several bikes without complaint; they continue to feel as solid and trustworthy as they were the day I bought them.
    However, these cranks can be hell to install, especially if you're using a chain guide. During muddy/sandy rides, grit also tends to get in between the bottom bracket cups and cranks, making a pretty ugly noise. I'm not sure if this noise affects anything, but it's not pleasant.

    Purchased At:Price Point
    Strengths:looks cool, light
    Weaknesses:OK, I bought these from pricepoint and the spindle to arm where the splines mesh to come together was not right! the highest torque value is 60 ft lbs, I put 80, no luck. PricePoint told me to mallet the arm and slowly tighten, back off, repeat. OK, no real luck and I thought this was a bad idea to keep going. I used an old mechanic trick of heating one side and freezing the other. I got it on. Remember to use all 4 spacers and 3 (three) seals or you will get side to side movement with the arms across with the BB bottomed out (regardless what the directions say)!!!Here was the real fun part. After stripping my arm remover tool I had to put my bike on my 20 ton shop press to remove them, the press popped off the spindle once and drove the arm into the BB damaging the bearing and seal. (I came real close to cutting the arm off not to damage my $2G Frame). Well I got them off and I sent them back to PricePoint, they didn't seem to interested in exchanging them since I had installed them? I guess if there is a defect you have to know before installation of the product. They said, without seeing the product, it was instalation error????? I am a ASE certified Mechanic of 6 years, I think I can follow directions on intalling a crank. Seeing the review before this one makes me think it is from a bad batch, I called Race Face with no avail on admitance to ever being able to put out a product with a .001 inch of a machining tolerance defect, and they also said they could do nothing for me, I had to find a dealer to warranty them. I'll keep you posted on how PricePoint takes care of me as well as how the cranks work out. For now I am forced to leave the lowest amount of chilies.
    Similar Products Used:bent shimanos
    Bike Setup:wall-mart speacial
    Bottom Line:I guess take them to a machine shop and have them measured to ensure they will press together and not have side to side movement before you try assembly so race face, pricepoint, or your LBS will not automatically shout installation error!
