    Stem options for 1 inch steerer

    Almost all the stems available are made to fit 1 1/8 inch steerer tubes. I have two bikes with 1 inch threadless steerer tubes. One currently uses a Ritchey Pro 1 1/8 stem with an insert. The other has an older 1 inch Deda stem

    I want to buy a shorter stem for each bike but cannot find either inserts or 1 inch stems. Can anybody recommend my best options.

    Thomson and VO makes a shim. I cant really recommend any good 1" stems.

    I second that. Get a shim. I think I saw one on Wiggle.

    shim... and also a 1-1/8" top cap (unless you use a spacer above the stem). Watch the stack-height of the stem vs the height of the shim too; Thomson makes more than one size. Ideally, you want a shim that is a mm or two below the stack height of the stem or the top-cap may not fit snugly.

    Any good shop should have shims. There are no 1" stems available anymore.

    Some stems come with shims too, the last Ritchey I got came with a shim. Your LBS will have them though.

    10 years ago, just about every 1-1/8 stem came with a 1" shim. Back then it was still possible to get a 1" stem. They were beginning to become rare. (they looked "skinny" compared to 1-1/8 stems)

    Buying parts to hang on your bike is always easier than getting fit.

    The problem with finding a 1" stem is that is most likely going to be NOS and be sized for 26mm bars not 31.8mm bars, unless that is what you want. Then Ebay is your friend.
