They are... but my concern was more about fitment taking into account existing frame hardware, hence i was thinking standard DU option.I was under the impression those poly bushes were the latest and greatest in bushing tech?

Yep positive... and on the BB it shows the side + direction so I'm 1000% sure. It starts to thread in a bit and then just stops being able to turn by hand and I am not sure I should "force" it with a longer wrench, etc..You sure you’re screwing in the right direction?
There is often some distortion of the BB shell from welding, and the tightness doesn't always completely disappear with running the BB taps through. If you can turn it easily with a spanner then go head. If it starts to take some force then I'd be getting the threads chased. The tool is a bit exxy to buy for home use.Yep positive... and on the BB it shows the side + direction so I'm 1000% sure.

So I tried again yesterday and it threaded in okay at the start. I screwed it in a bit, then out, then back in, etc... to make sure it wasn't going to get stuck. It got to a point about 1/2 way and it got tougher so I then started using the tool - it got a bit tougher but then all of the sudden no movement. I got a bit freaked out and tried to back out the BB but it was way hard all of the sudden so I used a hairdryer to warm up the alum and finally backed it all the way out. It ended up eating 2-3 threads off the BB (not the shell of the frame at least). I think I def need the threads re-cut or chased or whatever it may be called. When it 'ate' the threads off the BB the material seems to have like 'stuck' into the BB shell threads. The threads are all there in the shell and there's no stripping of them, but now there is a little bit of extra material stuck to them. I'll add some pics so you can see what I mean. So I'll def pickup a new BB obv as this one is toast now.There is often some distortion of the BB shell from welding, and the tightness doesn't always completely disappear with running the BB taps through.

Edit - should get the powder coat faced off the edges of the BB shell while it's in the shop. Not all shops will have the tools to do both
Cool I will check in with them and hopefully they can get me sorted with nice, clean threads. It's a pretty horrible feeling when you're turning a wrench on a part as delicate as the bb and all of the sudden it just stops and jams :/Summit should be able to help, otherwise Astroboy should be able to sort you pretty quickly.
One with more photos ...Probably take that to another thread
Time to go press fit! It is the way of the future.Cool I will check in with them and hopefully they can get me sorted with nice, clean threads. It's a pretty horrible feeling when you're turning a wrench on a part as delicate as the bb and all of the sudden it just stops and jams :/
It doesn't look or feel like it's cross-threaded so I am hoping a chasin n facin as you said. Hard to get a good photo of it, but it looks like just junk material in between a few threads. Hoping a cutting tool will just clear that junk out, straighten up and clean the threads.Yeah nah ! cross threaded or badly in need of chasin and facin
