I have wanted a Chris King bottom bracket for the last 10 years. I am now the proud owner of a blue one, mounted on the Mojo SL WTF NE (New England). :thumbsup: As an extra post-Christmas treat, I purchased both the grease injector and the supah special CK BB removal / installation tool. The tool is a whopping $80 (flame away - I wanted this more than a Lopes Link, which you will notice is absent from my bike), but it fits on the BB cup with an ethereally eerie lack of friction.

The attention to detail and quality of machining on both the grease gun fitting and BB installation tool is far beyond what is necessary and IMHO qualifies yet another example of CK art.

In response to a few inevitable questions:
1) No, I have not ridden the bike with the BB installed, yet. Note the copious amounts of snow and snowboard racks mounted adjacent to the bike tray and lack of Nokian 296 studded tires (which are currently on the Ti hardtail). Not that I could tell the difference. The real test of this BB is the service life, and this Mojo is only 3 months old... It does seem to spin a little better when you rotate the cranks better than the XTR

2) No, I do not have King hubs on my bike. I had them on my previous bike, and loved them. However, I ended up with Hope hubs because they were easily orderable from Notubes.com when I ordered up my wheels. So far, I can't tell the difference between the hubs, BTW - both are loud and colorful and seem to be built in a bombproof fashion.

3) I have not yet tried the grease injector.

4) I did not install the unit. I couldn't comment on how easy or hard it was. I dropped it off at the shop, and it was done 90 minutes later while I ran other errands.

5) Yes, the my "old" XTR unit is for sale. PM me.

Of course, this thread is worthless without pix, so here are more than are probably warranted...

Best looking grease fitting evah...

not corrosion

Very Nice bottom bracket. Show that lower linkage some love. Got a little corrosion going on down there. Check out the 4th picture.
Hi,

Thanks for inspecting the pictures! And it's cool that this may be the only time I can provide an authoritative answer on this subject. :D

First of all, I do live in New England, and unlike other climates, I am regularly fjording rivers, Barney Holes (so named after the Massachusetts representative to Congress for his mud slinging propensities) and the like, so this area gets alot of abuse, and not much love. This is why I have been pining after a King bottom bracket for years, although to be fair, my previous sealed XTR M751 sealed unit was going strong after 7+ years of service.

Anyway, I digress... I did check out the section you mentioned, and it is definitely dirt. I applied the HID lamp at close range to it and picked at it with an awl just to be sure. I guess I need a new digital camera with better color accuracy, now.

color match and price

I doubt Chris King is concerned about color matching our bikes. I have four separate non-matchin anodized blue colors: links, King BB, Hope II Pro hubs, and anodized blue spoke nipples. I would love for them to match, but after a typical muddy ride no one can tell the difference, anyway. :D

I have lost track of the crazy money spent on this King obsession. I think it was 100+ for the BB, 30+ for the grease fitting, and then $80 for the installation tool that I'll never use.

Where did you order the cup tool and grease fitting? I can't find anyone that sells it...does King sell it direct?

Also, when you installed the center sleeve, did it click or sort of pop in? Do you have to apply pressure to it to get the o-rings to seat? I just got mine and it feels like there is a channel in there for the o-rings to sit in. Thanks

The cup tool and grease fitting were order from my LBS, Ace Wheelworks in Somerville MA. I think that any shop that is an authorized Chris King dealer can order that for you.

I did not install the BB myself, so I have no idea whether that sleeve clicks or pops in or it's assembly relationship to the o-rings. I have only called Chris King customer service once (ring drive hubs apparently are not greased to work at less than 32 degrees farenheit...), and they were very helpful. I would imagine you would have the same experience calling and asking them about the BB assembly.

there are videos in the mtbr interbike coverage showing how the injector works. a surface on the tool pulls the delring ring open inside the cup and injects the grease from there. The purging grease exits from under the rubber seal ring on the outside of the bearing. No fuss, no muss, no disassembly.

I just wonder if the spline pattern on the cups is the same pitch as Shimano as I already have the socket style install tool.

just replaced the grease last night

Quick update (sorry no pictures)...

I just replaced the grease last night. Gosh that was easy.

Step 1: remove cranks

Step 2 (one time only) - load the grease injector with grease

Step 3 - insert grease injector into non-drive side. There is a rubber seal, and you can basically snap it straight into the BB

Step 4 - attach grease gun and squeeze. The old grease comes oozing right out

Step 5 - repeat steps 3 & 4 on the drive side

Step 6 - reattach cranks

Total time for steps 2-5 was about 5 minutes. I spent most of the time reacquainting myself with how to remove and install the XTR cranks.

For those of you who have regreased bottom brackets in the past, this is a comparative heaven on earth...
