...or is it the sign of a problem?

I had to push my bike for about 200 yards yesterday (due to getting lost and finding myself in stuff that wasn't rideable :oops: ).

Anyway I noticed that when doing so the cranks keep turning...I cant remember it doing this before and just want to catch any potential problem early.

Could it be a casette/freehub issue?

Thanks!

    No, they shouldn't turn. Can't think of what that might be. Freehub? Possibly not even an issue. Any play in the cassette? How does the cassette feel turning it by hand when off the bike?

    Why was it un ridable? Was it mud? If mud that could get into the chain, cassette, FH ect and cause it to gine more than usual.

    Thing to check is with it all clean, just riding down the road and take both your legs off does it spin?

    Doesnt mean theres a big issue, probably just a bit grungy in the cassette, which is causing it to stick. Probably time to strip down and clean (the cassette, not you).

    The freehub bearings still create friction (doesn't matter when your peddling as its doesn't spin!), a number of my bikes have doen this, some crud between cassette and spokes/hub will also encourage it - no worry.

    cheers guys, think I'll give it a good clean tonight and see if that sorts it.
