Hi folks. Having an issue with the above. I wanted to replace the bearings that were fitted on a used frame i purchased. Went onto ebay and got the below..

Removed the lower bearing that was in the frame and it seems higher than the bearing that i received.. ( i would add a pic but not sure how too!)
Been a while since I replaced my Hightower headset bearings but from memory there are 2 different bearing heights for the same type of bearing. You need the smaller one. It was a minefield trying to work out what I needed but ended up going with a Hope pick and mix
From Santa Cruz bike archive:
Hightower 1
Headtube/Headset:
Tapered - Integrated Headset. 1-1/8" Upper bearing and 1.5" Lower bearing. S.H.I.S. IS 41/28.6 IS 52/40
Hightower 2:
Headtube/Headset:
Tapered - Integrated Headset. 1-1/8" Upper bearing and 1.5" Lower bearing. S.H.I.S. IS 41/28.6 IS 52/40
The IS52/40 matches the ebay listing. It is possible that the seller sent you the wrong thing. How tall is the bearing?
I fitted a Hope J to my girlfiends bike this summer. It uses a crown race seal which the old one didn't.
The one i took out was 8mm and the replacement was 6.5..the seller says the one i took out was the wrong one which would tie up with what boardinbob says, there's also about a 2mm gap between the race and the bearing, is this normal?
That doesn't look right I agree.
