Fitting a bottom headset race – with no tools!
I’m sitting in my flat trying to fit a pair of exotic carbon forks to a road rat. I have Allen keys , screwdrivers and a hammer. The bottom race is off the original Cotic forks and now I have to try and seat it on the new forks.
I could try and seat the race by tapping around a the inner edge with a screwdriver
I could add extra spacers under the stem and then hit the top of the stem / steerer with a hammer. With a block of wood in between
Or I could take it to the local German bike shop!
I also have to lengthen the hydraulic hose on some magura brakes as well. Are they easy to bleed tool less ?Posted 4 years ago
Or is the LGBS the best option?
If you have a cylinder hoover with an alloy tube then that will slip over the steerer tube and seat the race just right, my hoover is a 20yr old Electrolux dolphin and the suction tube is an exact fit for a 1 1/8th crown race but i have used the tube from a Henry before with similar success. 😀Posted 4 years agoSteve-AustinMember
you ‘can’ seat a headset race and headset cup for that matter using the forks and tightening the top bolt… you should not compress the bearings, and may have to use some extra washers, spacers etc to get the right pressure distance. its bodgetastic but it’ll work if you got no toolsPosted 4 years agoMogMember
The metal tube/pipe from a vacuum cleaner (or other bit of pipe) works well.. slid down over the steerer and tapped with a mallet..
Yep, used the ‘Henry Method’ last week on a pair of carbon forks (& steerer). Slightly dinked the end of the pipe though as I turned it upside down and knocked the pipe end against the concrete garage floor. Currently using pliers and file to get the flippin’ pipe to fit back into the hoover!
Still, crown race seated a treat.
I imagine the result will be me spending more money to fix the problem I’ve created as a by-product of saving money in the first place.Posted 4 years agoNorthwindSubscriber
What headset is it? If it’s a decent one it’ll most likely have a sealed bearing, which means the crown race isn’t really a race- the bearings don’t sit on it. And if that’s the case, then you can just cut across one size to split it (like many are from the factory) and slip it on effortlessly.
Failing that, I have an ancient, massive crown race off some old wreck which I drop on top of the new race, then using my #1 favourite whacking tool combo (a Thor hammer my grandad stole from the RAF after the war, and a rear axle out of a Suzuki SV650) I pummel it.
The rampant bodginess of method 2 shouldn’t put you off using method 1 😉Posted 4 years agovincienupSubscriber
I was just about to ask a similar question…
‘old standard’ 1 1/8 Hope Headset with split crown race.
I’ve fitted it with finger pressure and mounted the fork experimentally to the partially built bike.
I was going to ask if I should give it a good bounce and adjust/thump it with a tube of some sort but I gather from the above this will not be required! 🙂Posted 4 years ago
Much as hate my Henry, with a vengence, (how such a shit awful piece of design can still be sold is beyond me), I thought brutalising the hoover pipe will cost a lot of money to rectify.
So it was down to the DIY store – and 1.18 euro and a waste pipe later ….
Job done, race seated.
The waste pipe will never see active life in plumbing again, but will be a great “race twatting” toolPosted 4 years ago
Thanks for the suggestions 8)
