Saddle on Kilo TT frame moving.
 

So I recently put together a Kilo build from bikeisland and I have a question. I have the stock seatpost clamp and a thompson seatpost for this bike. There is no grease except the framesaver I sprayed in the frame. I've been lowering the saddle height so that my friend can ride it, and when she's done I'd adjust it back to my height. Here's the problem: when I tighten the seatpost clamp, it seems like everytime I adjust it, I have to tighten it tighter/harder for the seatpost to not move left to right. I fell last night and I noticed the saddle moved a bit, so that means the clamp wasn't tight enough.. My question is, is something being warped? Seatpost, the seatpost clamp, or the frame itself?

Overtightening the seatpost collar can damage the post. You shouldn't need that much torque (50 inch pounds ought to do) to hold the saddle stable. Sounds like the seatpost is slighly too small (I think Thomson seatposts come in .2mm increments so its easy to have one that looks/feels right when installed but is just a bit too small). Not sure what the seat tube diameter is on a Kilo (26.8, 27, 27.2?) but check that and make sure you have the right size post. If that's right, try replacing the collar.

I made sure it matches with the spec's that bikeisland/bikesdirect supplied. Could it be the seatpost is getting worn down from moving it oftenly? I thought thompson is supposed to be a better one?

Thomson makes excellent posts; I have two. I doubt the post is the problem. The clamp isn't tight enough. Try a new one.

Will it ruin the seatpost if I don't replace the clamp soon? Or can I just ride it with it super tight for the time being?

You'll be alright for time being. If it were a carbong post, I'd worry, but those Thomsons are tough. Thomson site says its posts can withstand "350 foot-lbs of torque" You'll probably end up stripping the the bolt or even snapping the bolt head off before damaging the post.

Thanks, that's what I needed to hear.
