    i weight 260 and have had great luck with truvative stylos on both my am/fr and my xc bike.

    if i did it again i would probably go shimano SLX as they seem pretty light but i'm sure are very strong. DH strong

    shimano SLX or XT is what i'd go for... can get em for 100 and 150 aprox if you look... that includes the BB...

    sir crackien what model stylo you using (newer 2 peice?) got an older square taper and it's doing fine... but not the siffest thing out there for sure

    I'd go SLX. I have the double and the triple model. Both are stiff cranks, but the double has steel inserts for the pedals, better if you lean more towards the aggressive side of riding.

    It is super freakin tough to beat the XT cranks for 80% (made up number...) of the riding most of us will ever do. Having said that...i'm a huge fan of my Race Face Atlas AM cranks on my RFX. They are in the middle of the whole light/heavy thing. I've taken them off road gaps, jammed up/through rock sections at a crawl where there are high side loads/shifts/etc and they are stiff as hell. A bit heavy for a pure XC rig IMO. The bearings are average and as with *every* external BB set-up you should have a good shop face your BB to ensure the faces are perfectly aligned.

    I'm riding Middleburns because they're supposed to be really strong and stiff. They seem great to me, but I've never really had a problem with cranks. I'm using square tapers. The way I heard it, Middleburns are like the Thomson of cranks, so I went for it.

    donalson i have ridden the past two generations of the 2-piece stylos. i pretty much love them and i don't plan on replacing it unless i get more money or i break/bend. that being said i will probably end up needing to replace them sometime this summer as they will be used outside of their intended purpose.

    middleburns are great cranks but EXPENSIVE! and do they make a two piece version yet? that would be an awesome crank

    i have shimano hone's with 2 rings, has a chromoly axle and steel pedal inserts. i think i opted for the 2 ring over the 3 because the 3 had an aluminum axle instead. these cranks are really nice and stiff. also have an old square taper set of race face turbine forged something form the 90's that are equally stiff and 180mm.

    chain reaction cycles in the uk has really good prices on shimano stuff, even with shipping to the US. i would look there if you want shimano. i think they even have xt's in 180mm.

    also, sir crackien recommended stylo's. i'm guessing he is not running the isis stylo, as the isis version i have is the flexiest crank i've ever ridden. i'm 6'4" and about 275.

    Yes, they are expensive. I got mine used on ebay, from australia actually. I think because someone decided that square tapers weren't cool anymore.

    I have been eyballing those and the Holzfeller and the Saints. I am leaning towrds the Diabolus at this point. How big are you? At 280lbs and dropping four feet occassionally I find myself cringing in fear like a virgin in her first scene with John Holmes.

    personally i would not buy the diabolus as they are seriously over built, and wicked heavy. the new saints are alot nicer than the older one as they are both stronger and lighter.

    in reality if you are keeping it about 4 feet or so then the new SLX stuff will last just fine as would the xt.

    i have done many 4 foot drops even on my stylo cranks and i weight in at 260 without gear and i normally carry my fair share of stuff seeing no one else i ride with does.

    Agreed with crackien. XT will take you pretty damn big as will Atlas AM cranks. I regularly go well over 6 foot and top out about 15 feet now for drops and 15-18 foot gaps on the Atlas AM cranks. Diabolus have their place, but in reality most of us will never get there.

    I bought them when I was 270. I am 230 now. They are heavy but I dont care...I trust them to take what I dish out. If weight is a concern then definitly go with these guys recomondations. They know their stuff and have taught me a lot.

    I have put (2007) Race Face Evolve DH cranks on both my son's bike and mine (Giant Reign). We both abuse cranks for different reasons. I'm heavy (260lbs to 300lbs) and he's just a bit of an animal. The RF Evolve DH cranks have been bomber for both of us. I also have recently installed a set of RF Evolve XC (2008) on a hardtail. They are not as robust looking as the Evolve DH and frankly look a little more slender than the 2007 Evolve XC cranks, so I need to give them a little more time/use before I will consider pronouncing them 'clyde-friendly'.

    I should add I wanted 165mm's and not many cranks come in 165 as far as I could tell when looking. Good Luck!

    I am ONLY...240 lb but Saints, Atlas and now Middleburn been very good to me.
    I think though its a little more about how you ride and less about your weight.

    I just swapped out the LX cranks on my Ibex Ignition for the SLX double and I swear I can tell a slight difference in stiffness. Could be NBS, but I swear I can tell the difference.

    I am now making it more difficult by including the desire for 180mm cranks. This leaves only a few options including the Altas AM and the Shimano XT. Not to thrilled about the Middleburn or Zinn stuff nor do I want to do a BMX conversion thing.

    Atlas AM are a lot stronger than XT. Race Face Deus is the crank that's on par with XT (strength and weight). The Atlas AM is closer in strength to a DH crank than it is to an XC crank...

    Just get the XT's, I"ve got them in 180mm and I'm 270 pounds. After trying all sorts of other stuff over the years from profile BMX cranks and all sorts of DH stuff, have come back to XT's and they can't be beaten. They are boring and common, which I don't like (ha ha) but there's nothing better out there.

    Of course, for every XT vote I will get an Atlas vote. Perhaps I can use parts from both and rename the mess Frankenstein or King Solomon.

    i would put money on that the XT cranks are actually stronger than the Atlas AM cranks. one thing that many people forget is that the cranks strength has much more to do with how it is constructed than how much it weights or what it is made out of. right now shimano has the best crank tech on the market and they are using all the right materials as well. there are many DH people that are running the xt crank and i have only heard of one or two issues and i get those issues are caused by and extreme case even by dh standards

    I have always had good experiences with Shimano stuff and have been leaning that way. I also spoke with one of the guys at the LBS and he suggested that using Xt cranks, cassette, deraileur and a better chain will help the whole drivetrain. Last season I went through four 22t cogs, three rear cassettes and five chains. I was using a FSA crankset, SRAM cassettes and some chains kept in a barrel full of oil. Perhaps making a comprehensive draintrain will help some of these problems go away. Any thoughts on this theory?

    There are only two (reasonably priced...) cassettes clydes should consider: Sram 990 and Shimano XT. They both use an aluminum carrier and stronger pinning system. XT drivetrains are nice. I only run either Sram X9 or XT stuff for drivetrain, period.

    Cranks? Hard to beat Atlas AM or XT.

    I actually know some people (engineers) in the industry who did strength tests with XT and Deus. The Deus spindle was stronger than XT and the arms tested the same. Atlas uses a heavier walled spindle and thicker arms than Deus, so Atlas AM is absolutely stronger than XT. XT uses a proprietary 6000 series aluminum where Race face uses 7050 or higher. XT's are nice, but I personally know 2 people that have ripped the pedals out of their XT cranks because of the 6000 series aluminum. XT's are primarily an XC cranks (no matter what people use them for) where the Atlas AM is specifically all mountain. A bunch of Race Face's pro riders were riding the AM before the Atlas FR came out. The FR is basically the AM with and even heavier spindle and slightly beefed up arms...

    I use xt's and slx's they are very good.I weight about 235lbs with kit.I would go slx for price and they are only about 75g heavier than xt and 100% stiffer and stronger.

    The SLX were my first choice two months ago but I could not get them in 180cm. I really had only six choices and the two of them were unrealistic, two I did not like and therefore I had to choose the XT's. Listen to me-*****ing about an upgrade!

    The XT's are working fine so far. They are very stiff, installation was easy enough and the 180mm does let me drop the seat a little. And they are very shiny.
