XT Cranks for DH???
- Thread starter spoke80
- Start date
I think for DH they'll be fine, if you're going to be doing big drops, you should look for another crankset.
I'm tempted to. I've been running them on my jack-of-all-trades hardtail and after putting them through the paces of dirt jumping, super rocky trails, and drops in the 3-4' range I'm beginning to think they'd be up for the task for my big bike. My XT cranks have been rock solid so far.
Drops to flat you're probably right. If you're hitting tranny they should be good to go. I've had the same set of XT's (the old '02 model without the cobra-flare thing at the spider) on three different frames in almost three years now. Pretty much our entire team ran those cranks on their Foes bikes last year, the only problem they had was the cranks bending when they'd hit something. If your bike has a low BB and you're racing a lot, I'd probably pick up something a little more burly. But if you're not trying to pedal through rock gardens or your BB is more average, I wouldn't hesitate to recommend 'em.Brian HCM#1 said:
I've got an older set of XT splined drive hollowtechs on my Bullit right now...holding up find. I'm only replacing them because the shop that installed the initially forgot a washer on one side and crushed the splines.
The new XT cranks with the integrated BB should hold up to a lot of abuse...that being said, the Saints are only a little more money but are way more burly. Depends on what you want, lighter weight or strength...

And that is the quandry. The saint cranks are cool but they are heavy. Lord listen to me, I'm starting to scared myself with all this weight hubub. I blame Profro, he started it!
James,
I have a DH9 so the bb is low but do you think it would be an issue?
James can't talk now, I was just on the phone with him. He talked straight and I just bought a Thomson Elite stem, a ProTaper Bar, and a flat crown for my slider plus.
BTW these are the weights I figured up. Let me know if I'm wrong on any of the numbers...
New XTs - 860g
Profiles with Ti Spindle - 926g
Saints - 1027g

Yeah the DH9 is a pretty low bike. If you've had a problem hitting your pedals in the past then I would probably look at the new 2-peice 760 XT cranks rather than the '03 guys we're talking about. Actually I would probably just buy the new ones anyway if the money part isn't an issue. The only downfall to the new Octalink2 stuff is that the bearings aren't as well protected from the elements, but I think new bearings are about $4 a side, which isn't enough in my mind to justify not running the new setup.
Anyway if you don't want to shell out the $$ for the 760's, I think the 754 style arms will be okay as long as you go 165 length.

No BS, just a guy talking about experience that he REALLY has. No local bike shop smoke screen. Plus he called me back to ask if I had bolts for the crown. Most places wouldn't even care to look, let alone call me to ask.spoke80 said:
Ben, I could give you my cane creek ad-10 off my broken sugar. You might loose some travel and slacken out your bike, but just the offset of your new fork...as well as dropping some serious weight. Plus I've got the older XT's you could run, as long as you like using time ATAC carbons for DH (cause der stuck on).
But sarcasm aside, I do like the new XT's on the xc bike. And seen photos of pro's racing 4X on them. Maybe get a lighter bb instead of the big one you have? I know mine is a tank and your not big enough to need 4 bearings.
Side note: Gonna try out the shoulder today on an xc ride, the chain saw incident didn't slow down the recovery too bad. And I've been cleaning the office and found all these little people muck boots. MAybe we can hit up a ride this weekend?

my xt hollowtech 2's have kicked ass all season and have taken every huge drop and jump iv thrown at them. imo way stiffer than my old truvativ set up. oh and btw save some money, order the crnk arms through qbp then get any of the cups for the race face outboard bearings (can get gold bling bling) and your money saves about 75 bucks at cost

spoke Im glad you askd, I had the same question... 
I'm running the '04 XT 2-piece cranks on my Turner DHR and have already knocked them on a few things and they're rock solid so far. I'd need way more ride time before I'd recommend them 100% though.
PS - I'm a weight freak too. Mine weighed in at 682g with supplied XT bearings and a single Blackspire 40T chainring.

what are the individual weights on those. most places i have seen say the holzfeller dh cranks which only have 1 ring weigh 680g i think. most bottom brackets are like 290-300 arent they. atleast the listed weights.profro said:

I've run the new xt cranks all season with zero problems. I'm about 205lbs with gear and I'm not super smooth but maybe a little smoother than average. I've used them only for downhill racing no big hucks, but I do jump everything I can on the downhill course.
I usually run Profiles. Not because I bend cranks, but because I like to pedal thru rock gardens when I shouldn't. I ripped pedals out of 2 cranksets last year before going back to my trusty old Profiles.
Decided to give the XT's a try this year when I got my new frame. Gotta say, the new BB setup is slick. Chainline adjustment was a snap. Works great with a E13 guide on a 04 Turner DHR.
Two weeks ago I hit a rock with a pedal stroke, hard. I knew instantly I had to have ruined them, but they felt fine. Checked at the bottom of the run and they had a tiny nick in them. That was all.
If they make it thru all of next season. I think they'll be a winner.
Profro... In regards to the weight. I think your 860 gr includes all 3 chainrings and inner chain ring bolts. You could deduct 60 to 80 gr for the extra 2 rings and bolts. So your looking at about 790 gr with bottom bracket. Thats pretty light. Also I think you need to add the weight of the spider and a chainring to your Profile weight which will make them pretty much the heaviest, even with the Ti spindle. The Profiles are amazingly strong and worth the weight penalty. Especially if you've ever ripped a pedal out on your race run. If the XT's don't hold up then I'll definately go back to the Profiles.
I say for the XT's if you're worried about weight and the Profiles if you need indestructibility.

Just now seeing this. Gonna be in the hood working on some grant stuff in the rain all day but I'll give you a shout when I get back to the office.spoke80 said:
Short ride yesterday, Toby isn't a trail riding dog, he just saw the water at concord and took off towards it. Then he kept running infront of me and stopping. Then randomly took off towards the water again while he was behind me and it took me 20 minutes to find him. Chili is a much better trail runner. But, I can pull up the front end and I can take a mild crash on it. CAmelbak digs in though.
yo - buy/sell??!!
you've put the new V10/VP-Free/keep the old V10 debate in my head. I'm loosing sleep.

what about those new HONE cranks? Aren't they supposed to be 'all mountain' and the xt's xc? 
Are those weights with or without rings? That'll change things a little bit. Profile are seriously tough cranks, but all depends if you do your mechanical work and if you're prepared to spend alot of time setting them up initially. If a shop installs them, well, that'd be a good optionprofro said:
The XTs are with rings.
The Profiles were without spider or rings. The only place I could find the weight was danscomp.com and I didn't think to look for the weight of the spider or rings. maybe I was hoping too much. I am running Profiles because they are so freakin tough and stiff. I was tired of stripping pedals or bending arms. Oh well.
The Saints were with a single ring.
The Hollzfellers were with a single ring.
Its a tough decision that Spoke and I have. We ride at a place that really abuses equipment. So having Shivers and Profiles really saves days and lots of money to replace broken stuff, but we are racing too much and outside of Windrock that stuff becomes a liability rather than a plus.

On a side note, my sone stripped out hte threads on one of his Profile cranks. I know there are kits out there to Heli-coil in new threads on aluminum cranks but has anyone tried it on a Profile?
He also wants to ditch his Profiles on his 20" for some Saints. But I was thinking getting the XTs instead. As far as price goes, the shop can order just the arms, cups and bearings seperately for less than getting the whole set up w/ chainrings.
I'm still leary of the external BB set up. It appears that the contact between the BB shell and the cup is on an edge. The load from a big hit would transfer from the bearing to the edge of the cup where it contacts the shell. It stands to reason you would have cracks develop in the BB cup on the circumference of the threaded part.
I've been using the same LX Octalinks for the past few years with no problems. But I pretty much ride once a week.

Peete, I think Profiles have a warranty against stuff like that. Give them a call and see. Worst they can say is no.
Are you saying that Shimano is compatible with another company? Crazy...dexter said:
Then you can run RF BB cups with Shimano cranks/spindle? Are the bearings the same size and all? That would be great if it were true and you could save some dough.
Thanks, I will. I'm pretty sure it's from Peter installing his pedals hand tight when he's a) too lazy to look for the pedal wrench he didn't put back from the last time or b) in too big of a hurry to look for the pedal wrench he didn't put back.profro said:
Either way, I'll be surprised if Profile has a warranty that covers teenage stupidity.
OK, I'm surprised. Just got off the phone w/ Profile. Very nice. Ship it to them w/ $10 for return shipping. If they can't repair it they will send out a new arm.
I think we will stay with the Profile cranks.

im positive that its compatable. lets just say i hate shimano but these cranks are making there way onto my street bike in a bit and nthen a set of hones for my 575 nixon combo droooool
That should be right, a lbs mechanic weighted them for me on a digital scale, and they are around that weight. With cups and all stuff. It was more like 1.1 kg.profro said:
