wierd crank problem(7 posts)

Bike has been doing this for a week. When I am off it and pushing it forward, the freewheel doesn't engage. The cranks will rotate as the bike goes forward. If I touch the cranks, they stop moving, so it doesn't take much force at all to make the freewheel engage. Is it just tight pawls on the wheels? (Mavid Ksyrium sl wheels BTW) Other than that there are no problems with the wheels. They engage just fine while riding, and they coast fine while I am on the bike. Could it be a loose BB? (Dura Ace BB) I haven't had time to check either, but was looking for a tip before I take either apart. Haven't had the freehub off the wheels, but have on my other K's, so it isn't a problem to do if needed. Too lazy to fool with the dura ace BB unless necissary.

It's the Ksyriums. Apparently some of them do this. I don't recall what the fix is but you might be able to find it by doing a search.

I can live with that as it will prevent slipage, which they suffer from late in their life.

dirt in your freewheel body. fix it, or later on you won't be able to coast and the chain will go slack and hit your spokes, yes that happened to me on the old 7 speed type of freewheel. Where you be ridin'? That must be aweful lot of rain and dirt rides. My shop puts it into some kind of solvent (similar to wd40 i think), then they pump some slick honey through it, and its nice and perfect.

woof the sprocket... no wait... i mean dog.

Won't Slick Honey grease get too stiff in colder weather? I'm not even sure about how well it work in regular temperatures, it will depend on how well it displaces I guess. In my opinion regular 80-90wt gear oil works best. Makes it run and sound just like a factory prepped hub. From the feel of it the original Mavic gear oil must be almost identical in viscosity.

Poster mentions Mavic Ksyriums. That is a cassette hub body. This is likely in the hub body and it isn't supposed to be there. It has NOTHING to do with the crank. How would the crank move unless something is causing it to? Crank bearings aren't built with drag in them to stop the rear wheel from rotating! Your hub body is likely at fault. (Although I've seen situations where a poorly fitted spoke protector caused this problem by touching the chain when it was in the largest rear cog.)

but since i ride a 7 speed for a training bike, it is all freewheel to me ;-)

If you live in warm climate where it doesn't get below 40, you can get away with slick honey, some bike shops do it even here in New England. Some just put a little bit of slick honey around the seal after flushing the freehub with light oil. shimano recommends oil, no grease. So just do oil yeah!

sorry for the confusion

woof.
