This is the Serotta headsup spacer which is no longer being produced. I've read
in the the archives that it's unnecessary- that the change in geometry is small
and some say it's even preferable to have the shorter crown on a standard fork.

someone said i should use a spacer from serotta in the lower part of

head tube to correct the length of new fork against original ones but

dont know what depth to get this should keep geometry correct ?
