Seat post slips - trying to get pitlocks to work
 

I picked up a pitlock set but i've been disappointed to find that it doesn't work with my seat post which was my main interest in getting it. it just can't clamp down enough. forcing it has produced some wear on the keys - twice annoying. i contacted the vendor and he made a point of saying that the seat tube shouldn't be greased but everything i've read says thats exactly wrong.

the original seat post clamp works perfectly fine although it does require some force to tighten it. but thats not a problem with a normal clamp.

any advice on making the seat post pitlock work? its a salsa casseroll single, if it matters.

try putting a washer between the pitlock and the clamp of the seatpost.

the anti corrosion benefits of a thin [but frequently renewed] layer of grease helps keep the aluminum post from
seizing over time in a steel seat tube..
put the original bolts back in , then .
the force of which you speak suggests the fit of post in frame could be mismatched,
reamed out a bit large, and so the post is Not quite right.

Carefully hand reamed seat tube takes time, mass produced bikes dont get that, [time=$]
but a precise fit wont need much force to hold the adjustment.

maybe a Ti post wont need grease..

or go back to the old technique of taking the saddle off. and taking it in with you..

Or simply clean it really well and use Carbon Assembly Paste. Using that will allow you to use less torque in order to clamp it, whether it's carbon or not.

use a gator grip socket instead of the key
