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.
