    RDO fork

    Does the RDO fork comes with a crown race ?
    If not, what crown race is recommended, including the diameter I need please.

    Any other items that I need in order to install it in lieu of my SID on my Hydro One 9 ?

    No because the crown race depends on wat bearings you use.

    I think you mistake a crown race for an expander. The fork comes with this expander plug.

    You have to remove the crown race from your sid and place it on the rdo.

    Thanks,
    No I am not mistaken. I know what is a compression plug.
    If it require a special tool to remove it, I rather leave the crown race on the SID
    I am planning to alternate between the 2 forks.

    the crown race needs to be compatible with your headset (specifically the lower bearing as sandokan said). there is a specific crown race remover tool or you can remove it the ghetto way but if you want to quickly swap forks your best bet is to buy another compatible race since they are cheap and stick it on the RDO.

    I don't have the exact part number handy, or the price, but I know we have them at the shop. Just email me at mark@probikesupply.com and we can get one out to you on Monday.

    Been getting a lot of emails about replacement base plates for Niner's so we created a product for them.
