I've just installed OS-Fit cups to my new frame and now have a question before installing crankset. I have SR Ultra Torque crank with CULT bearings, which I think requires no greasing before installation. But after watching this (http://www.youtube.com/watch?v=gjxEPtjk3yY) Campy video, I have a doubt, maybe this white substance applied inside cups isn't bearings grease.

Could somebody clarify this for me?

When you are greasing the insides of the cups, you are not greasing the bearings, just the cups and outer race. Greasing the cups is recommended.

Thank you for the reply. But cups comes greased inside with small amount of some yellow grease. Should I additionally grease them before installing crankset and if I should, what kind of grease should I use?

don't worry, finish the assembly per directions and go ride. This board is full of campy stuff lasting years with no extra grease/lube/oil/maintenance.

I would guess/bet/ that you would have to run the SR cranks under water with sand mixed in for a year or two before anybody could wreck them. Normal every day riding SR is over kill.

As uraqt implied, it doesn't matter really. Yellow grease or white grease, as long as there is a little bit of some sort of grease there it doesn't matter. Even if there wasn't any it probably wouldn't matter.

Most important thing is that you get the two ends of the crank fitted together properly with the little clip in the two holes on the right side, the wavy washer under the bearings on the left side and the bolt torqued up properly. And if you have the version with the Ti axle, remember it tightens anti-clockwise! You will completely forget that it untightens clockwise when you next want to remove it though - this is normal.. :wink:

While I am all for expousing the longevity of Campagnolo components, they still need to be treated right to make it to old-age.

For the Ultra Torque bottom bracket, you should be liberally applying grease to both the inside of the cups and the bearings themselves (make sure that you spin the bearings around to ensure that it gets inside the races). With respect to the grease, I really like the factory Campagnolo grease best (plus is smells soooo good). it is no secret that the factory Campagnolo grease is made by Kluber, so that is another good choice. I have never found a Kluber grease that is as good as the Campagnolo-version for bicycles, but it is probably way cheaper.

errr Geoff, OP has CULT bearings, where C stands for Ceramic

But that's not all. Friction of the wheel and crankset is extremely reduced thanks to the minimal lubrication system required by CULT™: only a thin film of oil in the place of the grease traditionally used.

Thank you, guys. Crank successfully installed. But i have another question. There is a small gap (1.5 mm) between left cup and crank arm. Is this ok? Crankset was installed using torque wrench with recommended torque.

Well if there was no gap you'd have a problem.

It's fine.

If you ride in wet weather, pack them full of grease, not the bearings, the cups and bearing interface. Youd want to keep as much h2o out as you can.
