Title: Tantan GR201 headset bearing depth
Post by: nicptx on January 24, 2025, 11:44:55 AM

I’ve ordered a TanTan GR201 and chose to run a Ritchey integrated headset that will fit the frame’s 52mm headset bearings. My questions is…
Does anyone know the top bearing insertion depth?
Ritchey recommends 8.7mm for a close fit. I’m assuming any deeper and the headset cover will contact the frame.
The frame is still in the mail for another couple weeks at least, just trying to avoid potential problems with the build.
Thank you!

52x40x7 but it depends on the integration system
I am using 51.8x40x8 bearing for FSA ACR

It depends on the top cap. It is very hard to say when you use other aftermarket parts. Maybe you have to grind or add something like a piece of rubber.
