I'm looking for a new crankset and have come to the conclusion that going full XTR isn't worth the price compared to the XT. So in making that decisssion and looking at cranksets in this price range I was just wondering if you would definitely go with the XT or maybe the RF Deus X-type crankset (roughly same price). Any other suggestions would be welcome, these are what brands I know and have used.

Bought the RF Deus because i liked the cnc look of the crank but prefer the XT mounting system over the "shim-and-guess the amount of endplay" of the RF system. The best bargain of the outbound bearing cranks are the M580 Lx cranks

The hollow XT cranks will be stiffer, more surface area than RF can get using their I-beam.

Apart from that, I think the biggest difference is the mounting. To take off the XTs you just loosen the two little pinch bolts and the cranks slide off and out.

To take off the RF cranks you must use a huge self-extracting bolt and the crank is basically "pressed on" just like older octalink/isis cranks. This means every time you take them on and off you are wearing out the interface. This won't wear them out or anything with normal use, but with the XT you can easily take them off frequently to clean them or whatever. Less steps and effort invloved with the XTs.

FSA Crankset Opinion

Hey there, I also was recently in your same shoes... deciding between the XT or Deus Crank and I got neither one. I came across the new FSA V-Power MegaExo and checked it out before purchasing. Found out it's a stiffer crank, lightweight and made to last longer than XT or Deus. Like ISIS design which make the lower end of the bike feel really stiff, no play at all, there's no Bottom Bracket, just a hollow solid thru axle with oversized bearings. I came out of an older XT Hollowtech crank to this and in my opinion, for the price, you can't beat this crankset. Make sure you look at the MegaExo and not the standard V-Power, big difference, most of the reviews on MTBR are from the lower end version. Hope this helps.

I'd go with the Shimano Deore XT cranks, a solid crank. Shimano makes things to last, I know somebody that is still using 3 year old Shimano Deore XT octalink cranks, and they're still good. If this is any testament to the strength and durability of these cranks.

The Deus cranks look to be between the XT and the XTR in weight. How do the FSA cranks mentioned here compare? They are almost half the price, so I'm on the line.

EDIT

I can answer this now. According to this page

http://www.weightweenies.starbike.com/listings/components.php?type=cranksets

The FSA V-drive megaexo (who remembers Voltron?) cranks, at about 986 grams are about 167 grams heavier than the RF Deus and about 100 heavier than the XT cranks. Actually, now that I look, they are 51 grams heavier than the LX cranks.

Somebody had to get obsessive/compulsive about this. I broke the seal, now have at it.

Personal Experience

I went with the FSA because it's a solid design, no BB, lightweight (even though not as light as other more expensive cranks, but what's 100-200grams when they're more durable) and the price was just right, the look sweet too. You'll feel the difference the minute you start crankin', I've included a couple of pics of mine. I hope this helps.

M580 vs M760

Can anyone explain the large price difference (about $100) between the LX and XT. Only difference appears to be the steel inner ring...this is easily replaced for <$20. Are the bearings identical???

Well I think its time for a reality ckeck but the outboard bearing system those FSA cranks are using is the same one used by Race Face, FSA, Truvativ. Take a wild guess who designed it. That particular standard was designed by Shimano and introduced with the 2003 XTR cranks. The particular design used by FSA is virtually a direct knock off from the Shimano design down to the pinch bolt and lock ring.

You seem to not be aware that not only do the 760 XT and Deus cranks use the same integrated spindle design and outboard bottom braket but that Shimano designed and Race Face was the first other to adopt it. The BB is compatible among all brands.
BTW I'm not sure if you're aware or you did it to change the chainline but your spacers are wrong. The two spacers go on the drive side. You can put them like that to reduce the chainline inwards by 2.5mm but the cranks will be off center.

I don't dispute that, but the FSA design is an improvement on Shimano's. My point was more that it is silly arguing about where a particular design came from and who "stole" what etc etc. At the end of the day, as consumers, we're better off buying the best solution available, which is currently the FSA Megaexos ;)

Except the V-drives are not hollow, so they don't have near the surface area that the shimanos do, so not as stiff.

Not particularly light either. 986 grams? Geez! Thats almost Saint territory. I've been looking at the new FSA external BB cranks and can honestly find little redeeming qualities in them. The only thing I can see saving the V-drives is they are cheap. But compared to LX they cost about the same and the LX is still stiffer, have better chainrings and are lighter. The K force carbon models are heavier than the XTR's, more expensive, and not likely to last as long. I find absolutely no point in using carbon on a crankset. It has absolutely no advantage and is just a matter of time before the metal pedal thread insert comes loose. Anyway, I'm getting carried away. I still think Race Face or Shimano are the only way to go when it comes to integrated cranks.

Yeah, I don't quite give them their due most of the time. I've used em and worked on em. The difference between the race face and the shimano ones is not huge, little easier to work on the shimanos, and a little stiffer, but it's not a huge difference and the race face models are very nice, there's no doubt.

OK, I was figuring the Shimano's are the better/stiffer bet and was maybe considering the LX version even for the almost 2lb weight.

Question for you guys - Would you buy a set of the older style XT cranks and BB used for $125 US? Does anyone know the weight of the old XT cranksets. The BB is sposed to have only been used for a couple rides (not sure about this) but the crankset has definitely seen some good use.

Saying that RF and Shimano Integrated Systems have the same integrated spindle system would be incorrect. The RF use splines and an oversized bolt to put the cranks together. Shimano uses Pinch bolts to put the system together.

No, I would not. That's a pretty big chunk of money, and for $200 or less, you can get the new LX cranks with the integrated bottom bracket. Even though they are a little heavier, they are much stiffer (so better power transmission) and you could save your pennies and get lighter rings later on perhaps.

The old XT cranksets+bottom bracket weigh almost exactly the same as the new ones, there isn't much difference there. The new crankarms weigh more than the old ones, but then the old bottom bracket weighs more than the new one.
