    Mountain bike head tube

    Hello, first question here..
    I have an older mountain bike and was thinking of cutting the head tube off it, and welding on one sized for the newer 1 1/8" steerer tubes and related hardware as well. Actually I would set everything up, then have it professionally welded.

    My question is, one would this be worth doing?
    And two, what are the ID and OD dimesions of the tubing I should use, or can I simply buy something that is sold specifically for this purpose then just cut it to my desired lengths?

    Thanks

    Unless it's a VERY high-end bike (and made of steel, NOT aluminum), it'd cost more than the frame is worth. And if it IS a high-end frame, you'd destroy any value it has. Not to mention the nuts-and-bolts issues (alignment, geometry, etc).

    Short answer: dont' bother.

    If you are looking to fit a more modern suspension fork onto a 1" steer tube frame, there are 1" OEM and "franken-fork" options that are a lot better than hacking your frame apart.

    Also beware that if you go stick a 120mm travel fork onto an old frame with geometry designed for 60mm travel, the steering/handeling will most likely suffer.

    Thanks guys
    I was halfway thinking about the fun of doing it more than anything. One of those learn as you go things. My uncle runs the steel shop of a commercial construction company that works throughout the US, so the welding would be next to nothing if I had the setup ready to go.
