    I want to fit a tapered fork to a bike with a crown race reducer fitted.

    Hello everyone - first post - I've been a lurker for a while but I need help to fit a tapered fork to my bike which currently has a fork with a straight 1 1/8" steerer tube. My bike has a tapered head tube and a crown race reducer in order to fit the straight steerer. The bottom bearing is caged and seems wide enough to fit a 1 1/2" steerer (ID of bearing is 44mm). Do I just need a crown race and if so, which one will fit the caged bearings? Or do I need a new headset? Thanks.

    If it's a 44mm head tube you will need a new external lower cup and race.
    I got some bad ideas in my head.

    He said the ID of the bearing is 44mm, not the ID of the head tube.

    It kinda matters what the headset is which crown race will fit best.

    Thanks guys, I think I have found a 1 1/2" crown race to replace the existing reducer race. I contacted a dealer who sold my make of bike (XDS) and he thinks I will be able to use the existing caged bearings. It's being sent to me in the post so I will have to wait a few days before I will know for sure. Cheers.

    Yes, all you will need is a regular 1.5" crown race that fits the bearing angle of your current bearings, no need for anything else unless by some weird reason you can't find one to match.
    One day your life will flash before your eyes, will it be worth watching??

    Yup, think I read that and thought I was reading wrong, seemed a bit weird. If this is the case, unless the shop he got it from has the race for a tapered steerer to fit the caged bearings, probably easiest thing would be to buy a new bottom cup complete. Didn't say which HT standard his frame uses, so if he can figure that out, will make finding something easier.

    Thanks LyNx. Trouble is there are no markings on the bearing cage whereas the upper bearing is a cartridge type and shows 45 degrees. Itís a neco headset - I have looked through their range but cannot see any with lower caged bearings. I donít know how to determine HS standard. It doesnít appear to have cups so that would make it integrated I guess?

    Why not just pick up a new tapered headset? The NECO ones are only like 15 bucks, and bikewagon had some takeoffs that were 10 bucks.

    If the head tube of the frame is tapered, the bearings are likely sitting in a "zero stack" or internal cup. Integrated headsets will typically use a cartridge bearing, so that the bearing balls themselves aren't rolling around (and wearing out) the frame.

    I have seen manufacturers mix upper headset parts and lower headset parts. For example, I have seen with some frequency lately bicycle manufacturers using Cane Creek 40 uppers, but Cane Creek 10 lowers. And then in the spec sheet for the bike, they list the headset as "Cane Creek 40" rather than being specific about what they did. Kinda slimy if you ask me.

    Yes I looked at that but there is a bewildering array of headsets. How would I know which is right for the head tube on my frame?

    Yes, I have looked but there is a wide range of headsets and it is difficult to know which one would fit the head tube of my frame.

    1. Consult Cane Creek's headset fit tool.
    2. Ask a bike shop.
    3. Consult frame specifications from manufacturer for head tube dimensions.
    4. Remove existing headset and measure head tube.

    Let us know what frame it is you have, maybe someone knows the headset standard it uses, or try the Cane Creek headset finder as Harold suggested.

    Thanks Harold - I'll work my way through those suggestions.

    If you have some pics, or a link to the bike in question, it might be easy to ID.

    If itís any help itís an Air x6 frame made by XDS. XDS Boss 4 (2018) is the name of the bike. XDS make frames for others too and have different names - e.g. Flight Trail 1 has the same frame and is sold by Rebel Sports in Australia (which is where I am). I did email XDS a whilst ago but they didnít reply. Thanks.
