Hi all,
Currently building up a 2016 Stumpy Carbon, but I'm missing a crown race for the headset.
Bit baffled about what I need to order. The bearing specs are:
Upper - 41.8mm x 8mm x 45deg
Lower - 52mm x 7mm x 45deg
Have a Works one on the fork, but I don't think it's right as it rocks about like mad.
A full headset looks pretty cheap as it's an integrated one, but still no idea which is the right one.
Anyone? Please 🙂
I'm guessing the 45deg bit is the contact angle? So I guess I just need a 1.5 crown race with a 45deg angle?
I think the Hope CR is angled at 45 degrees. Not sure how the seal will play though. Cheap enough to try and split too
Thanks, I'll look at those.
We have a Hope bearing in the bottom of one of ours and the Specialized crown race fits it OK so I would have thought that a Hope one would fit the other way round. Bike Scene or one of the concept stores might have a Specialized one lying about. I have a box full of Specialized stuff that has come with bike frames but I dont remember seeing one in it that hasnt been used.
This may help

Thanks for clearing that up Tracey, I'll have a check round 🙂
