    Raceface Diabolus, No flex, no fussing around.

    Incredibly strong actually, but also discontinued. 1400g w/bb as I recall.

    Bearings are just ok, seem to last about 1-2 years, but quite easy to replace a bottom bracket. For the record I successfully replaced the bearings with higher quality ones, but at $25/bearing it's not much cheaper than a new BB which is much, much, simpler.

    Schwinn made a U.S. manufactured 1 piece forged steel crank that was probably stronger than anything you can buy today, and it weighed less than half a ton.

    I've reamed the sleeve out of two sets of hussaffelts! Getting a little tired of it, just looking for something better!

    Without bagging the cranks, Hussefelts are cheap and heavy.

    They are decent cranks for the cash but I would say if you went a reasonably priced set of current offerings you will certainly get lighter and possibly stronger.

    Just looked at the receipt and I paid $56 for my set of Truvativ Hussefelt 3.1's (plus $30 for the 100mm BB)

    I keep seeing profiles thrown out but all I can find is BMX cranks.

    Profile Racing E-Store

    I looked at them, and ... It's a pick and choose thing with Profiles.

    Have you thought of Holzfeller's ... That way you can keep your current BB.

    They make several different lengths of axle. The wider axles are suitable for 100mm bottom bracket shells. They offer all different kinds of single ring or multi-ring MTB spider options to fit their arms. Several here are using them.

    I use Profiles, incidentally because I can set the chain line to whatever crazy number I want.

    If you're going extremely fat keep in mind the shape of the crank - the axle ends *really* stick out unlike more conventional MTB cranks.

    I also like them for their simplicity in spirit, wish they'd make a lighter MTB specific crank though. I mostly just like the spindle design. "Here's a spindle, and some bearings, you put the spacers in it and cranks on it however you want."
    Disclaimer: I run Regular Cycles (as of 2016). As a profiteer of the bicycle industry, I am not to be taken very seriously.

    Been pretty happy with RF Atlas. Maybe not the absolute strongest, but good balance of weight/strength.

    I couldn't use Profiles on my Sandman, even with the longest spindle, because of the "straight arm" design. The arms interfered with the chainstays at their mid point. The bikes needs curved (ie, forged) arms such as the Mr. Whirly, et. al. due to the wide chainstay spacing. Other frames that will fit a BFL/100 combo may run into the same problem.

    I'd trust the e.Thirteen cranks for pretty much anything a fat wheel can handle.

    Profile cranks are by far the strongest, burliest cranks that I have used. Being a BMX rider at heart, I have always loved Profile. I got Profile cranks, BB, chainwheel and hubset for my 29er and it has been bomb-proof. However, like Andy said, they usually do not fit fatbikes. The longest spindle they offer is 6 7/8 inches long, or 174.6mm long. With a shell width of 100mm, an external cup BB, chainwheel and required spacers to get the cranks past the chainstays it could get a bit sketchy! I would love to try it though. Here are a few pics of my 29er with Profile gear. Other than Profile, the Raceface cranks look great or the e.Thirteen cranks for lightness and rigidity. They used to have problems with creaking a bit, seems to be solved though.

    Not sure if they’re “the strongest”, but I’ve had my Raceface Atlas setup on two fatbikes so far, it’s on the second set of bearing cups. 1,410.3 miles on my Surly Pugsley, at which point I transferred the setup to my 9:zero:7, which currently has 3,631.3 miles, so just over 5,000 trouble-free miles. Not bad considering I am always grinding up steep climbs (20%+ grades), bombing up/over rocky stuff (lots and lots of pedal/crank strikes against rocks), and riding through rain and mud throughout the winter. What’s more, they come in an array of anodised colours: blue green orange red purple.

    Middleburns with a Phil Wood BB. I've yet to do any maintenance on them after five years on my Fatback--which has seen everything from snow, beaches, desert, and dusty/silty gravel roads. Considering how abusive of a rider I can be and my genuine disdain for working on my bike, they were money well spent.

    Well, I'll say this then. Having bent the hussefelts back in the day, the holzfellers are quite a bit stronger and much harder to trash due to the alloy being better. I've had them come on a few bikes now and they are hard to fault, save for the extremely heavy BB. Otherwise, look at the cross-section of material and you can get a pretty good idea of what is going to be strong and stiff. Best would be a hollow structure like the profiles, as shimano doesn't really make anything hollow-forged for this market. Other than that, it's just varying degrees of "decent" cranks and nothing is going to stand out really. The ISIS BB is the biggest let down for most of these cranks (that use it) IMO. It's an ill-thought out attempt at matching the shimano octalink drive that used needle bearings to fit into the bb shell, but that's what cheap buys you. At least with the "gigapipe" versions they bearings doing fail much, even if they are heavy.

    The bottom bracket issue can be helped alot by using EnduroForkSeals replacement bearings or complete BB units. The key to his success it seems is larger ball size with better seals and slightly larger non-standard bearings if the bracket will allow it.

    No, that's not the issue. Enduro bearings work fine and I've used them before.

    The issue is the ISIS BB doesn't leave enough room for bearings IN the BB, when that was tried, they failed all over the place. They had to go to much bigger heavy external bearings and quad bearings. It's a heavy BB and the durability for the first units that used internal bearings was crap, while shimano didn't suffer from the same problem with internal needle bearings and ball bearings on the outer portion. This is why you don't see very many, almost no, lightweight ISIS BBs. If you look hard you can find a few that were produced many years ago, but they stopped due to extremely poor reliability.

    At this point, replacing ISIS external bearings with enduro isn't really necessary, the gigapipe ISIS stuff is plenty reliable, just heavy. Enduros are great for your shimano, race face and other sets if you manage to toast the external bearings.
