Hairspray + Alloy Seatpost ?

Raffles

My seatpost is an alloy type Controltech team 1 , the seat clamp I use on my Alloy caad8 is an M-Part one. Some of the roads on the club run are bump city and by the end of the ride I often notice my seatpost has dropped a little. I read online that some riders buy cheap hairspray which gets tacky and they spray their seatposts and then tighten the clamp and it works.......no slippage

I went to a shop and bought a £1 bottle of extra hold hairspray to do the job and my question is , if I need to remove my seatpost for whatever reason in the future, could the tackiness of the hairspray damage the seat tube ?

Remember it is an alloy seatpost going into an alloy seat tube and has anybody else used the hairspray method ?

No, but then never had this problem. Could you not use carbon paste instead?

If I took some grease out of the tub for the car I have in the garage and scraped pencil lead with a stanley knife and mixed them together, would that do the job ?

Sounds like your clamp isn't doing a proper job or you aren't tightening it properly.

It could also be that the seatpost's diameter is too small(a few mm is all it takes), hence why it's not holding in position.

Hairspray was being used on seatposts and handlebar grips well before anyone dreamt up carbon assembly paste. It won't cause any problems to your frame either.

Do you spray the post and leave overnight or is it spray and wait 30 secs then fit ?

Do I have to wipe the post clean of all grease that is on it, is there any risk of seizing ?

Is the seat post clamp the right way around? Mine used to slip if the bolt on the clamp was the opposite side of the frame to the frame slot. Try rotating the clamp 180 degrees or a try different clamp.

Wipe the post of grease. Quick spray and wait about 30 secs and put it in.

Works fine on my carbon post in my carbon frame.

You will need to do it again if you take it out.

Works really well on rollers too. So my Nan says.

Can't you just tighten up the clamp a bit more?

My dad's bike has an aero carbon seatpost with a carbon frame which used to slip about 2cm on every ride. He gave the seatpost a good clean with soap and water, and sanded the inside of the seat tube very slightly. No more slip

+1 to this.

If it is the correct size seatpost, just tighten it up some more! It's not like it's carbon and you're at risk of cracking it... A seatpost shouldn't really be slipping, it doesn't matter how rough the road is lol

spray on, insert post job done. i use gel spray, but its all the same stuff really and about 1/10th the cost of carbon paste.

does anybody put a thin line of grease round the top side of the clamp where it is holding the post to keep water out when you are washing the bike or is this overkill :?:
