    It's custom build. Carbon frame headset tube bottom is 1 1/4 ID is 47mm OD is 52 Top is standard 1 1/8. I need to fit 1 1/8 fork in this 1 1/4 bottom head tube. I need link to crown race for the bottom. Bottom bearing size is OD 47mm ID 34.5mm 45*. Standard crown race doesn't seat nice on this bearing.

    Framesets are generally designed/manufactured with a specific headset specification/type in mind, so when you say the crown race doesn't 'sit nice' - are you saying it's the wrong type for the headset?

    It's custom build non standard. Parts doesn't fit by standard catalog number.

    Usually the crown race comes with the headset you buy.

    I'd suggest you ask whoever custom built it.

    It sounds like you need a crown race reducer. Not easy to find for 1 1/4 to 1 1/8 which is what you'll need. Something like this r2-bike.com/CANE-CREEK-Crown-Race-110er-Serie-EC-ZS-IS47-30-1-1-4-Reducer-to-1-1-8-Aluminum might fit

    Thanks majster. I've just bought standard crowne race and rub it to 1 1/4. It's not perfect but will work for now. If someone needs quick cheap solution to fit 1 1/8 to 1 1/4
