Rear Wheel Problem

[Bugner]

Daft question time

I have normal derrailluer gears, obvioulsy when I spin the wheel forwards this engages the chain ie, connected to the pedals, but when I spin it the other way, shouldn't it just freewheel?? mine seems to catch and rotate the pedals backwards. Is this right?

When cycling home last night, there was an intermittent rubbing sound, when I got home and turned the bike other and spun the pedals, no sound eveything seemed OK, as soon as I staretd cycling again this morning, same intermittent rubbing sound.

Any advice appreciated. Cheers

It is fine

If you are going forward and you can not freewheel that is when you will have a problem.

If you lift up the rear of the bike and spin the rear wheel forward it should freewheel. That's the equivalent of rolling along with your feet still. If you spin the rear wheel backwards it will turn the chain and the pedals.

This sounds like you have a stiff link in your chain. Put the chain on the smallest sprocket and move the pedals backwards slowly while watching the chain over the sprocket. You should find that it will jump as the stiff link hits the sprocket. When you have identified the link at fault, grasp the chain with both hands with the sprocket between your grip and twist the chain from side to side. You should use a cloth to do this. This should free the offending link but if not then it used be eased using a chain tool.
As for the sound then it could be many things and you would have to specify what kind of sound. It may be the chain rubbing on the cage of the FD in which case the cable tension to this needs adjusting.

What dose this have to do with the freewheel?

When moving the pedals backwards the chain should cause the block to rotate backwards also. As his doesn't, it seems likely that a stiff link may be causing this. That's usually the case and I see an awful lot of them these days what with the salt solution now being used.
