Hi, so I took the detangler off this cheapy mongoose kids bike, but I can't figure out how to get the last bit off.

I had the stem off, down to the headset, but the headset doesn't move and the forks don't drop out.

So can I safely get the headset off and take the last bit of the detangler out, or is it stuck in?

Here's a pic of the bit I mean:

Looks like the headset cup is holding it in. You can knock that cup out but I wouldn't recommend it if you don't have a headset press.

Yes the bearing cup is holding it in as p1p1092 has said, I wouldn't recommended knocking the cup out and then putting it back in afterwards with out a headset press but it can be done with some careful hands, a hammer and a punch (or socket extension), then some grease, a hammer and a flat peice of wood to knock it back in. I never had a press when I had an older frame with cups you had to knock in, so always had to resort to carefully knocking it in and out. I'm sure there'll be a video on YouTube somewhere showing you how to do it.

Yep, that's one of those removable tabs that you put under your bearing cup for frames that don't have welded gyro tabs. Pain in the ass. You have to knock the cup out and are SUPPOSED to use a headset press to put it back in, but you can use a hammer and a block of wood to knock it in. I'd be really careful with it though, because you can crack the cups and that always sucks. Probably want to grease them too so it's easier to put in and will be easier to take out in the future. Don't force it or it will crack and you will have to buy a new standard headset.

Ok so do you think could just hammer the detangler tab upwards at the sides and that would push the headset cup off?

You'd have to take off the forks and hit it out from the inside, taking care to distribute the hits evenly around the cup.

Back in the day, I would just use a flat head screwdriver and a hammer to knock them out from the other end. And just put them back in with a wooden mallet. It never did any harm.

This is BMX, we don't need specialist workshop tools.

Never under-estimate what the right idiot can do in terms of damage, with any tool(but especially hammers)! laughing

I'm not sure how to take the forks off. When I took the stem off the fork didn't come out, think I tried tapping it with a rubber mallet as well.

The compression ring is wedged in there, it'll come out with a little effort.

Thanks. I just looked into how to get the compression ring out, but I noticed everyones compression rings have a little slit in them, so the ring can stretch a little. Mine doesn't have one though, so can't figure out how it's gonna come off, if the rings sat in a slot.

Ive knocked out the cups with a hammer. Just try and not be rough with it and take your time.

I'll have to take the stem off first to get a good pic. Try tomorrow.

Alternatively, you could run the gyro

The gyro was useless. Was a cheap no name low end mongoose put on their cheap bikes. I bought the bike 2nd hand and no matter how I adjusted it there was so much resistance the brake hardly worked. With a straight cable works brilliantly.

Got it off! Thanks everyone for the help. Now I need another spacer.
Unfortunately I think I've bent/squashed the bottom headset bearing cup by over tightening my home made bearing press tool.
So I need a new headset now! Will this one work? Dia tech d cup. My only concern is the one I have had one of those hollow bolts going through the stem. This doesn't, so will the supplied bolt still fit the star washer in the steerer tube?

Yeah, that'll work. Ditch the star nut that comes with it and use your own.

a bike shop should have just a cup. might be cheaper than a complete headset.

Thanks I'll try the bike shop. I just cleaned up the bearings and re greased them so buying new ones now would be annoying!
