It is ages since I had to fit a head set and feel a bit lost with the new sizes. Anyone expert enough to point me in the right direction.
I have measured the top bore of the headtube 41.9mm with a 3mm recess bore. Bottom bore 51.8mm with 7.5mm recess bore. See pics. Had a look at the Hope size guide, but could not match anything. Charge say use an FSA set, but the one recommended takes a tapered steerer and I have a straight 1 1/8th steerer.
Can anyone point me in the right direction? Thanks

Use the recommended fsa one and a hope crown race reducer for £8 bing

Recently done this with Cane Creek. Top and Bottom are different headsets so you cant buy one and it fits both parts. I bought the following:

Upper:
Cane Creek is42

Lower:
Lower Cane Creek is52

Brilliant, Thanks!
