Make your own crown race setting tool for $5

What you need.

A trip to Home Depot or your equivalent local hardware building supply store.

For a 1.5" fork or tapered steerer tube forks:
  1. PVC 1.5" cap
  2. PVC 1.5" coupler
  3. PVC 1 1/4" to 1 1/2" adapter
  4. PVC 1.5" (40mm) pipe, (3 feet long)


All this I got for $5 + tax.

For 1 1/8" Steerer tubes:
  1. PVC 1 1/4" cap
  2. PVC 1 1/4" pipe (3 feet long)
This is even cheaper, $4!

These two setups work wonderfully as PVC being much softer than aluminum or steel, will not mar the crown race. Nor will it warp the crown race as the PVC will give under impact instead of the crown race. All we are trying to do is drive the crown race to bottom out with the fork crown. For home use these solutions works beautifully.


  1. nice tip, but what do you need the coupler & cap for? Is this just for a surface to hammer on?

  2. I too wanna know why... & why so long (3 ft)?

  3. Hey Guys,

    Up the cap just makes it easier to hammer on. You could do with out. I just usually flip the whole thing upside down and slam it all against the floor.

    For 3 feet... that is just to make 100% sure all forks can be accommodated. An uncut fork for mountain bike can be quite long. I like to install the crown race and everything setup on the headset/headtube, with spacers, stem etc and then score the line onto the steerer tube 3mm below the stem protrusion then cut.

  4. Why the 1.25 to 1.5 adapter?

  5. This was a great tech tip. It worked great on my new Rockshox Reba 29. Thanks for the tip!
