I love my saddle like that...no clue why, I just do. It is basically as forward as it gets. As far as the rear rotor it's a odd story...I ordered the rotor and the adapter...well I ordered the rear adapter and not the front adapter...then I hear 8" rotors aren't always a great idea on a QR fork due to the fact they can pull the wheel out or something of that nature....so I just left it on my back wheel, if I sling myself back over the rear wheel some it's just as potent as my front brake and it doesn't fade nearly as bad...I'm still tempted to go 8" in the front though
