I'm willing to bet that Cannondale has some design tolerance issues with their Prophet lower swingarms pivot seats. New bearings will not correct this.

My right side bearing fit was so tight that I had to make sure it was percisely perpendicular while being tapped back into the swingarm. It actually took some major skill to get it in & out.

The left side bearing popped out like a seed from a ripe watermellon.

Something ain't right here.

Exactly. My feeling is that my swingarm was milled incorrectly. The new swingarm was delivered with the bearings already installed and so far has been silent.

I wonder if I should buy roller bearing in the same size, well maybe next time if the SKF blows up

As far as roller bearings go, I don't think they can support a side load.

I don't think so, this is from SKF website:
SKF single row cylindrical roller bearings can accommodate heavy radial loads and high speeds
I think thay may be better suited for this application, but I don't know if they are available in the right size (I'm talking about roller not needle bearing)

Yep, I was thinking needle bearings. Sorry.

Is it me? or I think you're both confused!

A radial load is one that eminates from a point, like the spokes from the hub of a wheel.

An axial load eminates along the same line as an axis (coaxial) or centerline: parallel (geometry), contrary to radial or perpendicular.

A radial ball bearing uses inner and outer races that are shaped so a radial load passes radially through the bearing. Most radial designs also support modest axial loads.

tapered roller bearings ? overkill !!!
Wonder if my bike will be making noises soon

Son of a....

Mine's making the noise, too. It's been making it for a while, and I just figured it was the bottom bracket. It's definitely the pivot though. I can stand up and pedal, it creaks. I can seat on the seat and pedal, it creaks. I can sit on the seat, take my feet off the pedals, move the bike side-to-side (shifting my weight), it creaks. Definitely the pivot. Great.

I have heard...

That C-Dale is recommending a new bearing kit & a gap filling loctite adhesive instead of grease in the lower pivot.

Mine is on order, I'll let you know how I make out.

At least, it's an easy fix.

Must be nice, the bike shop I got mine at doesn't want to help me out at all. They just told me to replace the bearings and put locktite on it. Seems they don't want to take the time to make it right. O'well such is my luck.

 

[Dan Gerous]

Are you serious? Change LBS...

I wonder which Loctite adhesive they're recommending. Depending on the type, it can make things very interesting if you'd need to replace the bearings again later.

I don't think they mean adhesive as in "glue", you better use the red Loctite, a sealant. Otherwise you'll need to replace your swingarm along w/ bearings.

You need to demand..

You need to demand that they contact their cannondale regional rep.
If they won't do it then you need to call or email Cannondale Customer Service.

I believe it's Loctite-262...

The Red type...And it's not something that the consumer should be doing themselves as there's most likely a process that they are trying to prove out before they end up recalling them.

Take it to your dealer & have them do it.
If they re-use your existing swing-arm then all the grease needs to be purged from the bearing seats and while they're doing that they might as well install a new set of bearings. This is a warranty/design call, not a worn out part.

That's what I'm going to do here soon. This ticking sound is driving me nuts. I know there is another Cannondale dealer somewhere close, so I may give them a call and find out what they can do for me.
