    Moving components from one frame to another

    Hi there,

    I've got two mtb frames. One is too large, but has a front shock and better components. The other is better sized for me and lighter, but poor components. Oned has a threadless headset and suspension fork. The other is threaded and has a straight fork. I am wondering how difficult it would be to move the fork over to the better frame? What issues might come up? If anyone has experience in projects such as these and would care to comment, I'd be grateful for any advice offered.

    Thanks

    Charles

    Frames don't care about threaded/threadless headsets, that only concerns the fork.

    The frame does care about the diameter: 1 inch, 1 1/8, whatever. If both frames are the same in that dimension, this will work fine. If the frame you want to use is for a 1 inch headset, you can only use a 1 inch headset in it. If it's for 1 1/8", it is possible to get adaptors to use a 1" fork.

    A very few MTBs use 73 mm bottom bracket shells, but most use normal 68 mm shells.

    Seatpost diameter may be different between the two frames.

    Seat tube diameter/front derailer mounting may differ between the two frames.

    Those are likely the only issues you'll run into.

    Thanks, Sheldon

    I did go and took a look at your website. I was worried about how the head tube would be with the headset, and you have put my mind at rest. I'll have to take them apart and do some measuring. Would I need specialized equipment to make the switch, or, could they be knocked out and pressed back in with a mallet? If the tools are needed, I would probably take them to a bike shop. Otherwise, I'd do the job myself.

    Cheers
