They Work

I recommend this product

ConsExpensive

ProsThey fit well

Not much to say, really.
The fit well and do the job of reducing the inner diameter of the head tube.
I think they are expensive (£18) for what they are, though ( alloy rings) but there's not that much choice.

Can I fit this shin to 1-1/8” fork steer to fit with the existing bearing race.
Thanks

Hi, I'm not sure I understand your question. These reducers fit to the frame not the fork. Thanks

New Fork!

Hi
I have a specialised secteur frame and a new fork which has a 1" steerer. Will this made the fork fit the 1 1/8 headset on the frame?

SJS Customer Service:

Hi,

These shims are indeed what you need. They are designed to fit into the frame first then allow you to fit a 1" headset and a 1" fork.

Thanks.
