hi

I am looking at buying the above but am a little confused on one thing.

I dont have iscg mounts so I know I need BB one however there is a SRAM BB one but I don't know if I need that one or not??

I have a Sram S-1400 39/26 on a Meta 5.5 2011

I have a feeling that the sram one isn't for my crank and I just need normal BB one but was hoping one of you knowledgeable lot would know.

thanks for your time.

And he will fit that how without ISCG mounts?

What BB do you have?

you dont have to have iscg mounts
still can fit it with just the b&b cup

Taking a guess here: the fitting of the standard BB and SRAM BB guides will be the same (a plate behind the BB), the difference will be in the chainline that the guide covers (from memory SRAM have jiggled their's a little to centre the rings more in relation to the cassette on some chainsets).

But it's for a single ring not a double anyway so it doesn't really matter...wont work either way
