For sale is the upper headset bearings (from Specialized), shim and cap, for an the Allez sprint range from 2016-2020. This came with a kit which I only needed one of the bearings for, therefore this is surplus to requirement. This is a perfect replacement, as it includes the whole unit, rather than the bearing, which if bought from a 3rd party, would need to dissect the new bearing, and place the inner shim and balls, into the old unit. With this, you can knock the old unit out completely, and put this one in (more smooth bearings as a result). They will be sent royal mail 48, and if you have any questions, I am more than happy to answer them.
