Video: Kirt Voreis & His Drone Buddy
I once rode with you Kirt. It's was about 10 years ago now. I was at a Western Open race at Kicking Horse bike park. My buddy was the event photographer and you invited me to session the shoot with you. You didn't know it at the time, but I grew up watching racing and despite being 27 at the time, I was star stuck and feeling like I was living a MTB dream. You pointed out this weird bank on the side of a fire road and started doing drift/brake slides up it. I wasn't sure about the choice, but who was I to argue? We went back and forth and it ended up being a great thing to session and great photos came out of it. Yours ended up a Specialized Ad, mines on my wall at home. That day is one of my fondest memories of riding, Thanks

First Look: Shimano's New XTR is More Than Just 12-Speed
@tacker: Agreed, but one of the premises of my argument is that IF you do maintenance (yearly for example). The chances of you ever needing cones goes way down.

First Look: Shimano's New XTR is More Than Just 12-Speed
@bman33: Well, we shall have to agree to disagree on a few points. I claim that I can indeed clean and re-pack a loose ball bearing hub faster than you can whip out your slide hammer and bearing press tools. However, we will never know as this contest of re-building speed will never happen. I'm making this claim because I also worked in a bike shop (not a wheel shop, but I've done a 'few' hub rebuilds as well). My second point is the 'IF' part of your statement. Why 'IF'? If you are willing to press in new cartridge bearings from time to time when they fail, why would you not be willing to do preventative maintenance once in awhile? In my experience working in shops it's because people do failure replacement not preventative maintenance. I suppose I am making an argument in your favor here...cartridges are better when you are addressing failures instead of checking your parts once in awhile to see if they are good to go. Maybe companies should make us both happy and just use these? http://www.skf.com/ca/en/products/bearings-units-housings/ball-bearings/angular-contact-ball-bearings/single-row-angular-contact-ball-bearings/index.html If Shimano went this way they could continue to claim superiority AND make them adjustable/failure replaceable.

@bman33: Shimano hubs are "sealed" bearings. I'm guessing you are referring to the angular contact design over single row ball bearings? Angular contact bearings are, and always will be, superior to single row cartridges for the bicycle hub application, which is why Shimano continues to stick with it. (unless of course they cave to consumer pressure for "Sealed" bearings or cartridges etc) They can handle more force from more angles, and the pre-load is adjustable. The reason the whole bike industry went away from them is money. It's much easier (read cheaper) to machine hubs and axles for 68XX series single row bearings (no need for threads or other methods of pre-load adjustments). No need to machine an area for seal sets either. The preload is basically done with the shoulder dimensions machined into the axles or specific spacer widths between the bearings. It's also arguably, a sort of hack, which some companies mess up from time to time. Some hubs always seem to have some 'play' despite being assembled properly, are the result of the two bearings being perfectly centerline with the inner and outer races. It's technically correct to have the centerlines this way but in a bike hub application it's no buenos to have any play at all. (Which 68XX have from factory, play with the inner races of some in your hand and see) Hub manufacturers actually have to have the inner and outer race centerlines a bit offset to provide the preload neccesary to make a hub with no play. This is technically incorrect, but it works and isn't really causing enough force to cause 'very' premature bearing failures. This is the reason that cartridge bearings only last a season or two under lots of ride before needing new ones. Shimano's bearing setup if cleaned once in awhile will last years if not decades. The seals on the other hand just went from hub seals made or specified by the hub manufacturer (Shimano) to the third party seals that can be specified by the hub maker when ordering bearings. (The 2RS part of the bearing code 68XX 2RS is 2 rubbing seals) Shimano hubs have great seals. As good as any seal that comes in an off the shelf bearing. There's plenty of old shimano hubs rolling around out there for decades that just need a fresh re-pack and a quick adjustment then they are good for another decade. I'd have to agree with the crowd about dropping the ball on the free hub splines. However, XTR has always been a group for rich early adopters and the most tech savvy or elite XC folk. If by the time the XT version of this stuff comes out, Shimano hasn't opened up the licence, they will have an issue.
