I have had it almost a year. Just maintaining the thing. Dont want it to start spraying oil everywhere and further contaminating my brake pads.loco said:
Brake parts cleaner on a rag is great for discs. If you have the pads out, spraying them with it helps a lot too.BurlyShirley said:
What's ****ty about them? Too heavy? Not strong enough? Feel stiffer than hussefelts and definitely lighter. Cost $160.stinkyboy said:Karma for buying ****ty cranks...
Yeah, I know they're LXs. Isnt that exactly the same as XT only with less material taken away for weight savings? Is XT just lighter crap?stinkyboy said:
Not faced, and dont care.syadasti said:
Oh, I know. Ive run XT cranks for a long time. DH'd and everything on them and never had an issue. Im just prodding for weak points in arguments at this point.johnbryanpeters said:
Don't worry. You will be fine. If they die, get some RF cups.BurlyShirley said:
thats what i said. They arent expensive. Screw it.johnbryanpeters said:
If I bend them, Ill gladly eat crow right in the lounge and say stinkyboy knew better all along.stinkyboy said:

Hey dumbass, you're whining that LX cranks suck. Maybe if you run them on a dedicated downhill bike they will fold, but somehow I doubt that most users will trash them, unless they're 400 pounds bombing down trails all day at whistler.stinkyboy said:
Because the uneven surfaces of a bottom bracket shell that hasn't been faced put undue stress on the bearings-the bearings are not perfectly parallel and thus can bind.Ciaran said:
If there's enough crap in the BB threads to cause the cups to go in at an angle of sorts wouldn't that be enough crap to prevent installation? In my limited (very limited) experience the threads of a BB shell are pretty darn fine. I've never taken a frame in to be faced but I do clean them really well and use a little grease.Dogboy said:
Well if BS was using a used frame, it would probably already have been chased by the last user (or at least somewhat clean from a BB being used in it before). You are suppose to chase and face a frame before installing any BB if you want to follow the recommended steps. Its much more important for external BB cranks though since they align on the outer face.Ciaran said:If there's enough crap in the BB threads to cause the cups to go in at an angle of sorts wouldn't that be enough crap to prevent installation?

I'm wondering if these failures aren't caused by a combination of things like the shell not being faced AND over tightening of the BB.
Just some thoughts, like I said my experience is limited. Thanks for the info!
Some higher quality mountain and road frames do come faced and chased at the factory every place (BB, head tube-for HS bearing alignment) and seat tube properly reamed (so your seatpost fits and doesn't scratch the hell out of your post). I doubt few if any companies face disc tabs on frames or forks. Some disc brakes have issues due to lack of alignment and Hope and some other various companies have tools to face the disc tabs too. I suppose if the powercoat was thick you could have to face the dropouts but over time hubs tend to bite in and eat the extra paint off but alignment issues can cause problems so you might have to at least bend them into alignment (park makes a tool for this).Ciaran said:Ah HAH! That makes mucho sense!
Thanks again. You have taught me somthing about bikes.
The XT external BB cranks are one of the best products that I have used. I raced them all year on my DH bike. In a year in which I cracked a frame, blew up wheels, and lost a couple derrailluers, the XT cranks held up all year.binary visions said:

I am now putting them on my slalom/trail bike I am building.
Light and strong.
LX's are Nice, I ran the older LX cranks, and XT cranks for years and really couldn't see or feel much of a difference between them. If they held up to me when I weighed 225, on the terrain out here I'd bless them for anything short of full blown freeride.robdamanii said:
My LX's are damn nice for the price.
Howabout XTRs? Any noticable difference in stiffness, or are you just saving half a pound in weight?Reactor said:
