    The four-pot caliper looks as though it contains four pistons - two per side; the two-pot looks liek it holds two - one per side. Take a look at the new Saint (M810) brake calipers, which contain four pistons.

    Edit. Beg pardon, I typed that an hour ago and pressed submit without re-checking the thread.

    That's a good price for 4-pot XT calipers, it was so good I got a pair to replaces my XTR's calipers. In my opinion, Shimano's best brake caliper. Good to see they brough it back with the new Saint.
    If I disagree with you, it's because you are wrong.
