Just purchased a 5.2 madone and cannot get the seat bolt for tilt/fore-aft to keep the seat in position. Anyone know the bolt torque rating? I am afraid of cracking the seatmast. I like the saddle to be about 6.5 degrees negative and weigh in at 230lbs. Every time the seat just cannot hold the tilt and swivels back. Also forget a precision adjustment - the angle of the saddle changes when you tighten the bolt. I have a micro-adjust seatpost on my '99 5500 and have NO issues whatsoever. Has anybody had any issue with this? Thanks in advance for any feedback.
