Q & A

I just installed an IS42/52 40 headset on a DJ frame I’m building up. The compression adjustment knob on the fork just barely touches the frame when rotating. I think an extra 3mm underneath the headtube would solve the issue. Will this work to replace my crown race? Thanks Chris asked on July 4, 2024

Hello, yes, the +3mm crown race is designed to push the fork uppers away from the frame itself.

My understanding is there are 2 types 36/45 and 45/45. Is this the 36/45 or 45/45? I bought this product and it doesn't fit my 45/45 bearing so I guess it is 36/45, but how can I tell? How can I order the 45/45 crown race? Hugo asked on September 3, 2023

The +3mm crown races are designed for 36°x45° bearings. You can replace the 45°x45° bearing you have with a 36°x45° bearing and it will work great.

Often bearing angles are etched into the side of the bearings.

On your website you don't mention if a product is 36/45 or 45/45. I understand that I need matching stuff, but it is a lot easier if Cane Creek would mention 36/45 or 45/45 on every crown race and bearing. I cannot find this info anywhere.

On the bearing product page the bearing contact angles are listed in the drop down menu for all bearing descriptions. https://canecreek.com/product/headset-bearings/

The crown races will always be for a 36°x45°, unless its noted in the description as being 45°x45°. All of our crown races that take 45°x45° bearings have that noted in the description. We'll see if we can add 36°x45° to the crown races as well to ease confusion.
