IP-256SL build [finished - photos]

[carbonazza]

I started with a Cane Creek 40 on my 256 frame.
The bottom bearing was so rusted it seized after a few (muddy) months.

I replaced the bottom bearing with the Neco that came with the frame.
Took it off when I changed to my new frame, and it is still running smooth.

I bought some cheap bearings from aliexpress, to replace when this one will die.
I see them(as well as bottom bracket bearings) as cheap and disposable bike parts now.

Thnx, will need to check which cheap one I should order than Do you, by any chance, have a link to the seller you're buying from?

When you search for "H373" on AliExpress, you find some cheap Neco headsets (complete).
The bearings are:
- NHB-6B (7H * OD41.8 * 45° * 45°)
- NHB-15 (8H * OD52 * 45° * 45°)

Don't know how to find only the bearings ...

Edit:

Use "ACB4052" to find some cheap NHB-15: 4 pieces for 17 euro ( http://www.aliexpress.com/item/4pcs-lot-ACB4052-40x52x7mm-45-45-degree-bicycle-headset-bearing/32501556182.html )

Edit 2:

Use "MH-P08F" / "TH-870" / "ACB845F" for a NHB-6B

Here is the last one I ordered: http://www.aliexpress.com/item/1-1-2-tapered-headset-bearings-SMH-P16-40x52x7-SUS440-stainless-steel-material/32241211712.html
This time it is stainless steel. A bit more expensive but just to test if it lasts longer than steel ones.

42x52x7 45/45 degrees is all you need to look at. There are plenty of sellers like MTB2223's reference.

The rear axle is coming loose every now and than. Really need to tighten the small screw (hex), which is annoying if you ever get a flat. Does anybody know a better solution/better axle?

Not a better solution, but a solution. Take a old inner tube. Cut it in a circle, with the diameter of the axle nut. Cut a small hole in the circle, a little bit smaller than the axle diameter. And put this piece between the frame and nut. It solves your problem. It did for me.

Thnx, I'll give that a try. Not sure why it would work (as long as it works, I don't care I don't understand  )

To be sure, the piece of inner tube sits directly between nut and frame and gets 'squashed' when tightening? Can you than go without the small screw? Or do you still need it?

What axle do you have? Any specific one that work really well?

Yes, that's correct. No need for the small screw. I'm using a DT Swiss axle with nut. But the axle doesn't matter.

Without the piece of inner tube, the nut getting loose because of the vibrations. Using a piece of inner tube, the nut won't spin that easy anymore. That's why this solution will works. And tighten the axle/nut more isn't the solution.

Regarding the nut getting loose from the axle:
While I never tried this as the problem had not arise, I was thinking using teflon tape (aka PTFE or plumber's tape) might help. They are really cheap and you probably have it already.

While I only did a short test ride, it seems to be a good solution. Thnx for the advice. Will now cut a few extra's a spares
