Which BB for a Shimano XT M785 chainset?

Hello,

What bottom brackets are compatible with the Shimano XT M785 10 Speed chainset? I've only ever had internal BB's so the externals are a bit of a mystery to me at the moment, but wanted to try them on a new build.

Thanks

Any HTII compatable.

I'd avoid Deore - they are pretty pants, but cheap.

Go for the SLX/XT version - or Hope if you're flush. Perhaps even the XTR version.

And btw, if you're buying the chainset - the BBs come with them usually. May need facing if it's never had an external on it.

Doh! Just read the small print on the website where I was going to buy the chainset from and you're quite right it says at the bottom "Comes complete with bottom bracket for 68 and 73 mm frames". I should read more!

Thanks

Slightly changing subject it also says "For use with 10-speed HG-X MTB chains only". Does that mean I have to get a specific chain for this chainset or will a KMC chain for example work just as well?

Youll be fine with any 10 or 9 speed chain (obviously depending on your cassette number of cogs)

I got shimano saint bb last month to replace race face team dh bb and its spot on was only 23.99 from halfords but was 21.99 on CRC but out of stock have to be silly not to get one at that price.

BTW - Saint has longer cups (screw part) so may not work with every frame.

Comes with adapters and you can get two different sizes but I may be wrong.
