Help needed fitting headset race.
Got my new kinensis 12K forks and headset today and was looking forward to fitting them. but I hit a problem straight away!
How do you get the headset race to sit fully at the bottom of the forks? It drops right down until it hits the last 10mm which is a fraction thicker. There is no way of pushing it down by hand and I didn't want to try hitting it with a hammer.
Anybody help me out?
Thanks.

long copper pipe.
or a crown race fitting tool."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

just been googling and the tools cost a whopping £84!!!
I like the idea of the copper pipe. i guess you just line it up and whack it down with a hammer.
what size pipe will i need for the 1 1/8 steerer? 28mm?

well the pipe needs to have the inner edge chamfered and that edge sit smoothly on the race.
size. sorry i use the correct tool or a headset with a split race. but an ID of about 34mm considering that the base of the fork is 30mm"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

I used a flat head screwdriver and a hammer! Not ideal I know but it worked. Just need to work as gently as you can whilst still hitting it hard enough to move it down. Work around it until it sits flush at the bottom. After my first and last try I'd wrap the end of the screwdriver in some tape to blunt it further still and prevent any marking of the race.0

Inch and a half grey plumbers drain pipe (no more than a couple of quid). Leave about an inch longer than the steerer locate and tap home. Alternatively turn the whole thing upside down and tap on the floor. Dont use anything metal, or you might be sorry... who said that, internet forum people ?0

When replacing a headset I've turned the old bottom cup (or head race) upside down and dropped it onto the race. I then tap that with a rubber mallet, the type used camping. If that doesn't work I've held an adjustable wrench over the top of this to provide a flat surface and attached it with a proper hammer. I'd feel nervouse about this if it was an expensive fork, but it has worked when I replace a headset and kept the old forks.0

You can make a headset tool with a 1/2" all thread rod, 2 nuts, and a couple of large
washers. The hammer, screwdriver, block of wood idea will work but can easily
damage your frame and or headset. Take it to the local shop if you have doubts.
It's not an expensive thing.

Thanks for the advise,
I've gone for the plastic tube route and got myself a 40mm plastic waste pipe from B&Q for £1.58. The fit is perfect. Will see if it'll work later on after work.
I could have easily taken it down to the lbs but I wanted to have a go at myself.
Thanks.0
