I've just bought a brand new seatpost for my roadie. Now, I am heavy (110kg) and ride a lot so I represent a limit load case for these sorts of parts. It passed the carpark test with everything knotted up to spec with a torque wrench, so I was surprised to hear it creaking like a galleon under full sail up the hills. Given I thought I had done everything right I would like to ask the hive mnd:
1. I put fibre grip paste on the seatpost (titanium frame) and then refitted the seatpost collar with anti-seize paste. The tightening bolts are loctited. I didn't grease or loctite the seatpost bolt. Would this significantly change the measured tightening torque?
2. I did not put any grease, antiseize or loctite on the rail - should I do so? The seat has titanium rails.
3. Given the design of the seatpost has a leaf arrangement, could it be possible that this kind of design is just prone to squeaking under heavy loads? I bought it because it has a good reputation for NOT squeaking on the reviews I read.
4. If it turns out that I need to overtorque the seat collar to kill the squeaking, what might be a safe margin? Currently it is set to 5 N.m as recommended on the collar. The seatpost doesn't appear to be slipping after one ride and the seat hasn't move in the rails either.
All suggestions welcome!
