Ive got to keep that seatpost i'm afraid, took me about a years hunting to get my hands on one,I had to ship one from alaska or some such remote place. Funny though they were everywhere once upon a time, they were tough as old boots so where did they all go?
Im not sue what the brakes are but I can check on saturday when i'm back at work. As far as I know they are the original specced canti's.
