Crown race without chamfer on fork side

As per the title, I am looking for a crown race with no chamfer on the fork side. Does anyone know of one please?

I have just bought a Stiletto UMS light fork, and its got a very narrow lip for supporting the crown race. I have had a look at a Cane Creek 40 which I had sitting around, and its got a chamfer which means the race will not sit square on the lip, but the chamfer will be resting on the lip and potentially destroy the lip.

    Looks like you need an aerocover http://34773.com/storck/?page_id=470 that's installed on the forks before the crown race is fitted -so the crown race rests on the aerocover rather than the fork. I've no experience using this.
  • Thanks, but I have an aero cover. Its just a carbon fibre shroud, and its not structural. I am looking for a crown race without chamfer.
  • I know its an ec34 type headset, my problem is that a Cane Creek race has a bevelled edge where it marries up with the steerer.

    The bevel is large enough/the lip on the fork crown is small enough that its possible that the crown will work its way over the edge.

    I need to find a crown race which does not have a bevel/chamfer on the underside. The alternative I guess will be for me to take a standard Cane Creek fork crown and have the bevel machined back to flat.

  • Not to worry. I discussed this with an engineer neighbour who said the bevel on the lower part of the crown race is essential. The lip on the fork will have a radius on it to avoid stress risers. Putting a crown race without a bevel on it would lead to the fork being damaged. So, no issue with the bevel on the crown race.
