IceToolz Crown Race Remover

Product Information

Put the fork on a wooden plank/surface, so it doesn’t get scratched or damaged. An old towel can be added beneath – just in case.

Use a caliper to measure the outside diameter of the cups. Next, measure the inside diameter of the head tube in two places, each 90 degrees from the other. Average the two reading. If the head tube more than 0.25mm smaller than the race, it may be reamed using the HTR-1 Headtube Reaming and Facing tool. If the race is between 0.01mm and 0.09mm, a different headset with a larger press race should be used. It is also possible to use a retaining compound such as Loctite® RC609. If the race is equal to or smaller than the head tube, a different race should be used. See discussion of press fit standards below. A Deda Elementi stem happened to be hiding in a corner of the workshop—glorious find … had completely forgotten that this piece of goodness was there. So, on it went. Way more elegant that the original piece of ugliness, you have to agree! You want the whole headset unit to be compact with no play, but still easy to rotate left and right.

Blade Replacement

What’s in a headset? This is an external cup headest. Right to left: crown race, lower bearing, lower bearing cup, upper bearing cup, upper bearing, cap or “dust seal”. After crown race has been pulled, loosen plunger assemblies and remove the CRP-1 and the crown race from the fork. Removing and installing threaded headsets requires specialist tools. Successful removal and installation depends on using them correctly.

It is also possible to replace retainer ball bearings with loose bearings. Grease cups to hold bearings, and place balls into cup shaped races. Leave a wide gap the size of two ball bearings, do not attempt to fully fill cup.We researched other brands and found that they were appalling quality straight out of the box and often more expensive too. A threaded top race screws onto the fork threads, then tightens onto the bearings which are either caged in a retainer or run free in the race. Having dealings with a paint shop in Taiwan is handy. You can usually convince the owner to do a custom job for you. Matching the Nishiki’s color is no problem. And it’s monochrome. No two or more color combos to complicate the spray. When replacing the headset (i.e. fork, or steerer bearings), removing the fork crown race (fork cone) can be problematic. Especially if the fork crown is wider than the race, so it can’t be punched off from the bottom. This post will explain the short and simple procedure and note the needed tools.
