Crown race installation- Freezer method?
Has anyone tried freezing their fork and heating the crown race prior to installation? I saw this idea here:

I was thinking it may help a little, but was just curious if anyone had tried it before.

I've put a ring gear onto a flywheel using that method . It worked just fine.

I just use a large crescent-wrench. Drop crown-race onto fork. Place adjustable-wrench jaws around steerer-tube. Tighten it up so that it is tight on the steerer. Slide wrench down steerer until it's resting on the race. Make sure jaws of wrench is at right-angle to steerer. Then slide hammer down next to steerer-tube and hit the wrench right in between the two jaws to push on them evenly. Usually takes 1-2 blows with the hammer and that's it!

Haven't tried the freezer method. But as many have recommended, I took my fork to the local big box and found a piece of PVC pipe into which the steerer tube just fit. A five-foot piece was the smallest you could get, and it was $3.24. Cut off a one-foot piece, put the race on the tube, put the PVC on the tube, and hammered the race home. Very easy.

An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

The crown on my Colnago Starr fork had to be faced with a special tool before the race could be hammered on.

hello
Do not hold the fork with dropouts resting on the floor. They may bend while pounding the race. I've always simply wedged the fork between my hand and body and pounded the pipe with the other hand using a mallet......even on carbon fork/steerer...

1¼" galvinized pipe is $1.88 for a 12" peice, although threaded on each end, at ACE Hardware. I hold the fork in my left, and hammer with my right onto the pipe. I've never done this with an expensive carbon fiber fork.
