Hope seatpost collars have that aluminum bolt that does not like to be over-torqued or it will break. I broke 2 of them! I had a recurrent ticking sound with my 350mm Ritchey Flexlogic 27.2 post in a sleeved titanium frame. I now have a titanium bolt in the Hope collar (with the standard aluminum teardrop shaped nut) and a U.S.E. Delrin sleeve and everything is quiet and has stayed quiet for 2 years. My post is at the limit line BTW.
