Man, as great as the IRO frame and wheels are, the Angus' parts have been a source of constant frustration to me. The bike is loud! When I am riding around, everytime I get the bottom of my pedal stroke I get a squeak. I have no clue what it is from. It happens when I am standing; it happens when I am sitting. The seat and seatpost are crap, and I thought that perhaps these parts were causing problems. I took them off and rode around, and the squeaking was still there. Man! I want to love my Angus but the parts make me wish I just bought the frame and fork.
