Headset problem fitting new fork
Moderators: robbosmans, Moderator Team
I am replacing my 3T Funda Pro fork with a new one on my 2008 Cervelo R3 SL. The steerer won't fit all the way through the head tube as the bit of the headset that fits into the bottom of the head tube won't slip down all the way to the crown of the fork. I.e. the steerer around 30mm-40mm from the crown is too wide for the headst to fit all the way. The steerer fits snugly but easily through the upper part of the headset

No, don't buy that tool, don't waste the shop's time.
Make one yourself, save your money.

You could also cut the crown race open and never have to worry about this any more.

I have a sneaking suspicion that Cervelo still used a straight steerer on that frame. Pretty sure tapered steerers came in a year or two later. That may be the OP's issue.

Yep. The ST were straight back then.
Do NOT use the hammer yet. Show us a picture of your fork first!
Assuming it is not a taper mismatch, and is just a "tight-fit" problem:
1. You can smooth off the steere tube a little and make it very slightly smaller by rubbing with 600 grit sandpaper. It really doesn't take much to go from "won't fit at all" to "slides right on".
2. Add some grese.
3. You can find a PVC tube of the right diameters at home depot very inexpensively. No need to buy the special tools.
? That sounds risky. Has it worked consistently ?

Actually many headset manufacturers deliberately make it that way. A properly tightened headset has the lower bearing pushing against the race from the outside (albeit at an angle) so all you need is at least 3 points along the circle that support the bearing. No problem whatsoever.

I've cut the crown race on a number of occasions, never had any issues.
