Grease for carbon products

[Johan Bornman]

ANY GOOD LBS SHOULD STOCK TACX CARBON COMPOUND WHICH IS USED FOR CARBON PARTS. CALL 011 6082003 AND ASK OUR SALES PEOPLE TO ASSIST YOU FURTHER.

 

PS THE PRICE IN POUNDS QUOTED LOOKS VERY HIGH AS ITS AVAILABLE IN A SYRINGE APPLICATOR AS WELL FOR ALOT LESS IN RANDS

Steve, here you go again. Why SHOULD we all use TACX? Or why carbon compound indeed? Perhaps if you explain why it would be useful.

Carbon Compound and Copper Compound are completely different, apart from the obvious.

 

Copper compound is used wherever this is a danger of two different metals in contact causing a galvanic reaction (making a weak battery and exchanging electrons) which accellerates corrosion. In aluminium the corroded by-product has such a huge molecule that it freezes narrow-spaced pressings solid. Evidence of this is quill stems and seatposts that are welded in forever. Copper compound alleviates this problem in two ways.

 

1) It doesn't emulsify and therefore doesn't encourage corrosion by trapping moisture inside the grease molecule.

2) It discourages the galvanic reaction between the two surfaces and retards corrosion.

 

Copper compoind is not a grease and should not be used on friction surfaces such as bearings.

 

Carbon Compound is different in that it contains fine grit that helps to stop the typical slide-down and slip experienced with carbon components such as seatposts and handlebars. Because carbon cannot be torqued as high as aluminium, it tends to slip, something us cyclists find annoying and which is outright dangerous. Anyone who's ever had a handlebar move under heavy braking will attest to that.

 

Carbon compound introduces grit between the two surfaces and impedes slip. Depending on the particular compound, it could also contain an anti-emulsifying agent. Because of the grit, carbon compound should also not be used for lubrication.

 

There's no need to buy an expensive tube of carbon compound if you're maintaining just one bicycle. Go to your local garage and ask the mechanic for half a teaspoon of fine grinding paste. Mix this with copper compound (much cheaper than carbon compound) or a little bit of grease and apply that to your slipping seatpost.

 

However, if your seatpost doesn't slip, it doesn't slip, so don't be seduced by tubes of fancy stuff just because it has carbon written all over it.

Simply put...because it freaking works. Put the paste on the handlebar/stem and seatppost and you will not have any squeakes or slipeage. The proof is in the pudding.

Tacx Dynamic Carbon Assembley...$24.99 for 80g...competitivecyclist.com

 

that's the stuff...used it the other day on my erm.......seatpost

 

LBS gave me a free sample. Works great.

Tacx Carbon Compound is designed to suit carbon whereby once applied to the carbon part be it a seat post or handle bar stem or whatever less torque is used to tighten it up with. If you over tighten a carbon seat pillar you can either ruin the clamp, crack the seat post or pillar and spend alot of monies replacing same.I have seen two identical seat pillars torqued up to the same torque,one seat pillar with Carbon Compound and one without and its amazing how this works.Many Look Frames we sold in the past suffered from this until Tacx Carbon Compound was introduced into the market two years ago.It cured many warranty problems with seat pillars.

 

Do not use anything else which mite have a lubricant in it.

maar agree ons dan dat copperslip gebruik kan word?

 

 

 

Oom Borman se explanation is to brits vir my om so lank konsentrasie te behou :-)

[widget]

I assume one should use the right stuff straight off the bat, mixing compounds is out of the question for me, I am far too lazy and have no clue about ratios between the compounds etc.

 

...........But for a technical person I guess it would be fine and relatively inexpensive.

 

That said, we use a lot of copper slip in the workshop, the technicians tell me its great stuff, - I wouldnt know, - but what I do know is we battle to get it commercially in the smaller 100g tubes like we used to, now we have to buy it in 500g tubs which for a private person is way too much, you use so little of the stuff it would celebrate 40 birthdays in your garage and you would still have 400g left.

 

Maybe the Auto retailers like Midas sell it in smaller retail tubes, I dont know, but dont buy 500g of the stuff, its just a waste.

I got a 100ml tube from Brights. Cant remember the price, but it was between R30 and R50.

100m ? That sure is a Looooong Tube

OK, as jy nie Grieks verstaan nie, wat van Afrikaans. Carbon compound is coppaslip met fyn sand in.

[Mudsimus]

Pops verstaan jy? Gooi sand in jou coppaslip. Dan is jy gewax. Mud Dee2008-02-19 03:20:48

how often must this tacx stuff be applied. I did a race this weekend in the rain, and it seemed to wash all the grease away and the seat post slipped. I will reapply some more carbon grease but ideally i would not like to have to reapply everytime it rains. Any other suggestions?

Idiot. Here you go again.

 

Carbon assembly compound is not Copaslip with fine sand. Sand would resist compaction at granular level and this could damage the surfaces on some components. Carbon assembly compound has tiny plastic balls suspended in a water-resistant lube. These balls compress under load, thereby reducing slippage without damaging anything. So if you are tempted to go the stupid route and mix fine sand with grease or Copaslip, don't. Use the right stuff.

I have been using the Tacx stuff for 2 years or more the same tube and it's not even halfway through...so money well spent.

 

It also prevents me from reaching for the hammer when I want to remove the seatpost.

Nice to meet you too.

 

Very brave, aren't you? Sniping away facelessly behind a veil of anonymity.

 

Sign your name if you aren't a coward.

But before you do so, explain to us how soft balls reduce slippage.

Being too lazy to hunt down grinding powder I had the choice of Vim or Micro Balloons - the latter being stuff I used to mix into epoxy glue to lighten it when repairing boats. Not knowing exactly what was in Vim I chose the latter and it worked fine. As for copper compound the price difference between 100 and 500ml is so small that I bought the 500ml and decant it into a syringe and use it on just about everything that I have to fasten that may have to be removed at some stage.
