Yes, they're cheap. This is why.
It's not.
It is it your business model pretty much.
not dissing it as i do partake when appropriately priced for what it is[ Tyres for example :wink:]
I had the same issue trying to take headset out of my 2010 Orange 5 frame, so nothing to do with On One in my opinion. I gave a shop £15 to take it out for me which they did with no problem because it was really not worth worrying about
Had the same problem with my 456 (not headset failure - needed to change for fork change). Luckily I'm a machinist so managed to turn a tool to go down the headtube with a small lip to catch the top of the cup. Took a while to knock it out, going gently all round the cup, but got there in the end.
I've still got the tool and used it on many other headsets..
I've just spoke to a shortarse mate who owns one of these frames (so it's a small) and asked him if he's removed his headset, if so how?., There's enough of a lip on the upper bearing seat to get a decent quality punch onto, a few taps on this in at the 3/6/9/12 o'clock positions and there was enough room to get a chisel punch on the outer face that butts against the frame - tap-tap and it popped out, i guess it depends if you've got the correct tools or not.
That's a useful response. Not as useful as one explaining how best to remove the headset cup, but we live in hope.....
How dare you druidh, are you looking to join TJ. To be honest I am very surprised that the designer of the frame came on this thread without a hint of help. But I am sure I'll be proven wrong very soon.
TBF, I don't think brant actually designed the c456. Wasn't that done while he was off doing Ragley?
I don't think brant/on one design anything.
Designing takes more than thumbing through a Taiwanese factories catalogue and pronouncing "dat one".
sterling effort on the trolling peteimpreza...if only you had a shred of evidence (and brains for that matter) to back up your bogus and obscure claims. What on-one does is the same as Cotic, but without the brand name tubing, custom butted tube profiles, small parts milling, ect. that drive the cost of a frame up. They offer affordable frames with well thought out geometry (not catalog frames with 90's era angles) for people without deep pockets. It's not hard to understand if you have the IQ and maturity level above that of a three year old child.
Now run along and go hide under that bridge you came from.
I don't mind damaging the cup as I will be replacing the headset but how best to remove it without damaging the frame?
The proper way to remove a bearing cup like this would be to use a blind bearing puller (like the one Konastoner pictured) and a slide hammer. Here's a video how:
Looking at your pics though I suspect you might have some fun as the bearing puller may not be able to force its way in between the frame flange and the top of the cup. You may well find it slipping. If this happens then you may need to start on the outside of the frame. Tapping a small pen knife blade between the joint of the frame and the cup. Work slowly round the head tube, little by little. You should get enough of a gap to the use the bearing puller. This method works on metal frames. However, I've never tried it with a carbon frame......!
Put it in a vice.
It's an unfortunate combination of cup and insert.
A vice will kill the cup of course but I guess you don't mind as that's why you're removing it.
It's certainly a dimension and issue that has been noted for future development.
Bikeshop. I wouldnt trust my usual seatpost/hammer mechanics.
If using the vice method I would use a dollop of wood/doweling or alloy round bar inserted into bearing housing to get a better purchase and help prevent cup deformation which may cause damage to fragile carbon 💡
All this started because the OP needed to replace the bearings which can easily and cheaply be done without touching the cups as he later worked out. It sounds like it's not an uncommon issue for a few frames but the solution is the same, stick in vice and remove. New headsets are £30/£40 so not really seeing the problem here...unless you needed to remove a CK headset.
It is possible to get it out without wrecking the headset cup but as brant said, you'd pretty much only take it out if you were binning it. Good job the Ali sleeve is well glued in!
Thanks to everyone for the sensible replies.
It's clear On One just stick their heads in the sand and ignore stuff like this and are only interested in selling complete headsets. Thankfully Superstar have better service than that and actually supply spares.
To be honest I like On One bikes. I really do. But sadly I've bought my last one. The poor design faults that just me and my brother have dug up on a small sample of 6 frames between us just isn't acceptable
Its a pity as the bikes ride brilliantly, but I just can't be bothered spending time and money sorting out the faults any more.
🙁
They offer affordable frames with well thought out geometry
Now who is trolling...
well not you, that's for sure. 🙄
if there is i'd use a collet on a slide hammer
That's more like it. What's one of those?Anyone can bodge. I want to know what tool does this properly.
that would be a blind bearing puller.
sorry, don't really get the issue here. you found alternative bearings ( we'll leave aside the 'superstar give better service than on-one comment' and the ensuing octopron). you wanted to replace the bearing, you found replacements, you fitted them. i've never found it necessary to replace the cup to replace the bearing, so if you want to change out the headset complete, you destroy the cup in the process, or you find a bodge to get it out. WGAS at that point?
Why did this have to come down to slating the construction of a frame/being arsey towards the company owner on a public forum knowing too well that he'll read it when the job at hand is simple?
It's possible to use the correct tool for the job along with another tool* in quite a few alloy and carbon frames with this step in it. It makes it so easy.
Others have mentioned two other ways above but why not take it to a flippin bike shop if it's causing grief?
*and I'm not referring to a hammer,either.
To be honest I like On One bikes. I really do. But sadly I've bought my last one.
Know the feeling PP.Bought approx a half dozen frames and many parts. Not huge money, but a good couple of grand in the last 18 months. Bought a Scandal. No dropout in the box. Told it 'was' there. Hold on, you have great eyesight from 200 miles away. Basically I was a blind liar. Got shirty back with them and my Xmas present frame stayed a frame until the new year when a dropout arrived 20 days later :roll:.
456C headset,genuinely a crap set of bearings. Are they interested ? Nope, made the sale , got your money, move on.
I have said to them I would never cross their palms with money again and I mean it too. Sad really as do like their kit, but just think that there are companies out there who want to genuinely help rather than just make a sale and not bother with back up. Others have been happy with them and at times I have been too, but a mountain bike will venture off road and will see moisture, but a headset lasting 2 wet rides and 10 dry ones is not an item I would have expected.
Del - Memberif you want to change out the headset complete, you destroy the cup in the process, or you find a bodge to get it out. WGAS at that point?
I replaced my Smoothie headset with a Works Components one to slacken the bike off (something On One re-sell too). If it hadn't worked out, I'd have wanted to refit the original headset. So I'd have GAS if I'd had to destroy the headset.
Like I mentioned up the page, I reckon it'd be reasonable to expect On One to replace the bottom cup under the circumstances. And tbh I reckon it's also reasonable that they should put the compatibility issue on the website, since they still seem to be selling both parts.
I reckon it'd be reasonable to expect On One
You do know they are yorkshire based don't you ;)?
My smoothie has lasted a year, still ok.
I was lucky to find a thread and link to superstar for compatible bearing.
Think bearings are classed as consumable parts.
Some good some not so good. Think Ive been lucky. Mind you I think using a mucky nutz and low pressure water to clean may be key.
PP rather than use the On One solution.....
I used a v large hose clip just fixed it on as tight as possible....
tapped it on one side rrepositioned on other side and repeat... bit of a faff but better than destroying the cup...
Just had a go at this and it came out easy (cup and bearing) with a standard Park headset remover - there's just enough of a lip above where the bearing sits to get some purchase - not at the top of the cup itself as the sleeve gets in the way
Ressurect- I need to remove a Hope headset cup from the bottom- is the Hope removal easy (i.e. old seatpost/hammer job?)
