i think it was a certain headset for a 1' frame that allowed a 1 1/8" fork to still fit thru the cups and bearings. anyone know for sure how to do this? thanks,matt

just gotta find a headset with bearings that are compatable with both your headset cups...just look to see what you have laying around...just a simple trial and error... but i reccommend doing this, the threadless set up is a better stronger set-up....

matt thomas · 2008-01-23 6:56am

i know the 1 1/8 is stronger. someone posted a specific brand 1" threaded headset that you just use the cups and bearings in a 1" frame and you can use 1 1/8 fork with the 1 1/8 headset spacers and bearing races.

yeah, i know what you are talkin about, but i think it was more along the lines of a 1-1/8" headsetthat was compatable with 1" cups....

matt thomas · 2008-01-23 7:43am

maybe that was it. either way. i even saw the pics of the bike with 1 1/8 forks on a 1" headtube. i sure wish i could rremember who's bike it was. DOH!

i did the convertion. i used tioga bear trap headset cups, then i had to find a spare 1 1/8 threadless headset to use the parts.

did you use the bear trap bearings?

OLDSCHOOLBMXER67 · 2008-01-23 10:15am

no, i used the bearings from the 1 1/8 headset.

thanks oldschool. now were getting somewhere!

simply stick the 1 1/8 system in the 1 inch cups.
depending on brand/style you'll have to find bearing cages that will slip over the fatter 1 1/8 steerer tube as well as spin on the 1 1/8 race.
cheapy wal-goose bearings are the most compatible i've found so far.
the 1 1/8 race needs to have a nice smooth taper rather than the style that has a couple of flanges that get in the way. again, wal-goose 1 1/8 races are PERFECT for this conversion.
start picking up those walmart bikes you see on the curb, boys!

This is what it looks like:

the cups need are the tioga mx-2 beartrap cups,or,any good one inch cup,that is of the deep type,not like hattas or tioga mx4',then the rest of the threadless set up,I do it with the bearngs only,without the race,and works smoother that way.just grease it liberally and apply the bearings one by one.

I just used a cheap yst 1" headset for the cups and used 1 1/8 bearings and rest of 1 1/8 headset. The 1 1/8 bearings are snug in the 1" cups, but doesn't affect the steering at all.

good info guys. anyone else done this another way, or different headset cups.

bmxninja · 2008-01-23 8:23pm

i say this needs to be a sticky in the resto section...many people always ask about this...quick reference is always good

Hey thanks for the info

Hi guys,

I'm new to all this but I have a 1" Homeless Player Headtube and a 1"1/8 Kore threadless fork. If I'm understanding correctly, I need to do the followings for the conversion:

1) Get a 1" Tioga Bear Trap and use the cup only
2) Get a 1"1/8 headset and use all except the cup

Is that true?
