Carbon seat post fitting

Postby Miklosh » Fri Feb 01, 2013 11:32 am

Hi guys

I'm fitting a carbon seat post to my carbon frame (seat tube seems to be lined with an aluminium sleeve).
I know I will need carbon paste to secure a good fix.

My original seat post is aluminium and removing the grease from this is easy, but not so easy to remove the residue from inside the seat tube - any tips?
How important is it to remove this residue? I'm sure I read somewhere that the grease may effect the new carbon seat post?

Thanks

Get a rag, stick it down there and just wipe off the grease - that'll do the job.

If your fingers aren't long enough use a broom handle or similar. Don't use your willy in case it gets stuck then it'll be really embarrassing.

Re the grease affecting the carbon seat post (or carbon itself) - what a load of baloney. It will do no harm to it whatsoever, ever. Slap a load of carbon paste on and off you go.

The best thing would be to soak a rag in your preferred carbon safe degreaser, and force the rag down as far as you can. A twisting motion will help with getting the rag right down into the frame.

Then pull out and repeat. Rinse the frame and leave to dry before carbon pasting and inserting your new post.

Carbon safe degreaser - now that's perpetuating the carbon fragility myth if I've ever heard anything.

Get some Jizer/Gunk/Muc off/whatever and slap it down there if you can't get the grease off with a rag - its all perfectly fine. Its a degreaser, not hydrochloric acid .....

Anyway, I wouldn't really worry about it - unless you have slapped bucket loads in there it'll be fine with a wipe down (and no, even bucket loads of grease won't affect the carbon, just the amount you have to do the clamp up to hold it in place).

Don't go chucking degreaser down your seat tube, your BB bearings won't like it.

+1 - a clean rag will do the job.

Please don't go rinsing the inside of the frame either

Thanks for the replies.
There doesn't seem to be that much grease in the seat tube anyway, so I'll try the rag/cloth and see if I can get it all out.

Yossie, no chance of embarrassment, its a 31.6mm seat tube, my willy wouldn't fit ;)
