Bit of a longshot, but I'm sure there's someone out there in STW who may have one knocking about 🙂
As it says really. I need the non drive side cup for a square taper UN54 BB. I have a UN52 but it's too small
I have a cup, but it's probably a UN52, will check later.
i'm pretty sure i have a plastic one.
email my tonight if you're still looking.
Got a heap of something like them but had never noticed the differences. Whats the size?
Hi guys... The UN54 is slightly thick in diameter than the UN52. I've just bought a UN54 off've STW but there was no non drive side cup with it 🙁 My old BB on the SS was a UN52.
Let me know if either of you have one please 🙂
Hello....can anyone help me please ??
As far as I'm aware they should be interchangeable - I've swapped them around in the past. The only difference is that they are shell size specific - the cup from a 73mm bottom bracket is 22mm deep and the 68mm cup is 17mm deep so will need to be used with the correct b/b shell size.
Never noticed a difference. I bung the cleanest in with the least knackered BB. Been doing it for always.
All mine will be for 68mm. If you want the exact model I would be guessing.
