another headset question cube reaction GTC

bladeone

Evening,
servicing the headset today and its gone beyond servicing, the bike is a Cube reactionGTC 2012 fox float32 100mm currently with fsa headset, cant read the numbers due to bad pitting I've measured with verniers and know which size I need I think :roll: but not sure of the angles of bottom bearings tried the cane creek finder but that didn't seem to show angles either think it may be the following link could anyone confirm this or link me to correct bearing
thanks

thanks nick does the 52/40 refer to the sizes and are all the angles common it that size bearing.

Theres that many fsa types im confused I wanted just to replace like for like if I went CC would I have to replace to the bottom bit which is fitted to bottom of forks

Thanks Again

You usually need to fit the 'bottom bit (crown race) when fitting a new headset, 5 mins job, so just change it then you don't have to worry!

Just to let you know I contacted a bike shop uk bikestore, very helpful guy there, I told them what I needed and I was correct in my OP the fsa 073 bearing the two numbers referred to the angle of the bearings and not the size the cane creek headfinder came up with 52mm and I needed 51.8 to be exact as my bearings fit directly into the carbon frame and are not pressed in.

Anyway thanks for the replies
