My bottom bracket (Shimano UN 52) got some problems and I want to replace ıt. The problem is that I'm in Istanbul and can't fınd a Shimano UN 54.
So I have to choose between a Chin Haur CH 51-70 and a Shimano UN 26.
Since I'm on my way India with my bike I really need a good bottom bracket, so which one is the best of the ones I mentioned?
And if anybody knows where I can fınd a UN 54 in Istanbul please tell me.

Shipped out of England Perhaps? There are a few UK shops
that ship internationally as a matter of course.
Wiggle, Chain Reaction, SJS,
Not really knowledgeable about the bearing set inside each of those 2 you mentioned.
Belt and Braces, get both , put one in the luggage to replace the other if failure happens.
China has a Space launch and Nukes , so are mechanically competent,
now whether the bottom line of profit over rode QC in the parts , is another issue,
beyond the scope of a low level forum.
I would get the Shimano. I have experieince with both Shimano and lesser-known Chinese bottom brackets, and I have seen both fail, but the 'non-Shimano' ones certainly fail more often.
