I got myself a bike to fix up. I changed the freewheel on it but I don't know how to position the nut after I put on the new freewheel.

If I screw it on too deep the chain will be too close to the frame so I am wondering if I am missing something.

The wheel is a quick release and I never worked with the quick release. I tried to watch some YouTube videos but nothing really helped.

    I wonder they mean the axle nuts?

    @Criggie: I just wonder about the 'freewheel', could it be a cassette?

    Does the chain actually get so close to the frame that it touches the frame?

  • Have you tried fitting this to the bike ?

Definitely a freewheel, and a brand new one too. I can only see the 6 sided axle nut, and no axle locknut.

Some designs have the cone nut buried deep inside the freewheel and then a spacer, and finally another nut on the outside, something like this:

Is it possible you replaced a 6 speed freewheel with a 7 speed freewheel, which is one cog wider? This may require rebalancing the spacers on the axle. You might be able to move a spacer from the left to the right side, and still have the required amount of axle body poking out.

Do note that a QR axle should end before it exits the frame - the QR's nut should be clamping on the frame not on the end of the axle. If in doubt, get it checked over in person.

    Hi criggie Thank you for your reply the original freewheel was a 7 speed but was all rusty and I put it the way it was. I think I am missing something Jun 14 '20 at 12:19
  • @PatriceSouef did you remove or move the axle nut? The chunky-looking six-sided one in the middle of the freewheel. If not, then the chain should be fine on the new freewheel.

  • @PatriceSouef second thought - did you screw the freewheel onto the hub completely? Did you put any kind of spacers behind it?
