|I have been having a problem with the seatpost on my 2000 KHS Flite 500. It slips slowly, usually noticeable about 30-40 mins into a ride. I am relativly heavy (6'1 182lbs) so it thought this could be a problem. I removed most of the grease in the seat tube, but I am worried that my seatpost might oxidize, binding into the tube. Its a real pain stopping to fix this so often, any advice would be great!|

|I put some grurling (sp?) in mine, no more slipping!|

|First, I'm not sure what type of binder you have on your bike but if it is like the old type that you see on steel frames like with a Campy binder bolt then look to see if the bolt is bottoming out on the female part before it's actually tight. This has happened to me more than once. If it's the clamp type then there is not much you can do other that roughing up the seat post with heavy sandpaper. Some posts are a little larger that others of the same diameter. the Campy TI post runs big, you might want to try that if all else fails. Put a piece of electrical tape 1/8 above the collar so that you can keep an eye on it while your riding, I do that with all my bikes. Let us know what happens. Good Luck|

|1. Verify your post is the correct diameter.
2. Be sure the 'male' of your binder bolt is not bottoming out on its 'female' end, if that is the type of binder you have. Do not over tighten - you will break the binder bolt.
3. Clean out the inside of the seat tube & the outside of the seat post. Rough up the inside of the tube with sand paper. Although only cosmetic - Avoid roughing up the outside of the post.
4. Definitily use a light coat of grease.
