How to Determine if Freewheel is not Dragging

[Splash]

How to determine this on a CK R45 rear hub?

Does it try to push the crank forward when coasting?
I fixed one that the complaint was the chain would slap the chainstay when the rider first let up on pedaling.

Thanks.

Don't know the answer to your question yet - but will look out for it when next i ride.

Is there a way to determine this without riding and just picking up the bike and spinning the wheel?

Also, how can i tell if wheel bearings undergo unwanted side loadings as the spindle is compressed form skewer tightening?

With the bike on the stand, if you spin up the wheel and backpedal, your rear der jockeys will bounce. If it's really bad, the freehub will even drag the cranks pretty hard

Does skewer compression affect freewheel action?

Do you think you have a problem?

CK hubs typically have a bit of drag from the seals when new. This decreases as they break in, but it takes a while. Also need to check the bearing adjustment frequently when new, and adjust accordingly. All of this is covered in detail on the CK website, and in the owners manual.

If you are spinning the wheels, or the freewheel by hand, and thinking they are not spinning freely enough - it is not a very useful evaluation of how the hub performs under load.

Do you think you have a problem?I can't say, but I suspect the best course of action is probably to 'ride more, think less'. :rolleyes:

1)Bike in stand, pedal bike, let go of pedal..does the spinning wheel turn the crankset? FH drag.

2)Adjust the rear wheel so you have just a little play in wheel in bike..take out and tighten hub bearings a RCH..then put back in frame and check for no play. PM for what a RCH is and I hope you are a guy.

Thanks guys.

Will play.

Yep _ I'm a guy :-)

Oh my God, I get it now. Actually, I have heard this before somewhere way back. Good advice though with this:

"Bike in stand, pedal bike, let go of pedal..does the spinning wheel turn the crankset? FH drag."

With CK hubs, adjusting hub bearings has little effect on the freehub drag. The freehub mechanism and the hub seals create a bit of drag even if the bearings are perfectly adjusted.

With your bike in the stand, turn the cranks and let it freewheel. If the chain over the top of the chainstays bow down a bit that's the drag showing. The cranks might not turn. If the cranks are turning because of the drag, it's really bad.
