CF Handlebars - How tight?

[Edition 507]

U can get a torque wrench that measures 0-25 Nm from The Tool Shop in Strydom Park. Got mine there for R1200. Sounds expensive but it is a lot cheaper than cracked carbon stems, bars, seat posts etc. If you are working on a carbon bike yourself, you need the right tools!!!

[Jokerman]

The general rule is one turn back from the minute you hear the cracking sound

About two weeks ago i went hardware store hopping looking for a torque wrench. I found NOTHING that can measure less than 10 NM. Chainreaction sells the Park ones for a reasonable cost, but i'm not sure what the import duty is on tools.

yeah, velo, did the same thing as you and realized you won't get them at any old hardware shop, you need a specialist tool shop, dunno if you have one in the cape though.

Well, if the thug hadn't been so greedy with his CRC delivery, we all could have had tools, books, dvds...

Found this cool site with customs tariffs. Looks like tools may be duty free:

The torque on a Deda stem is 8 nm.

When I imported my Hope disks and other stuffies I imported grease guns, bleed kits and other stuffies. There was no import tax , only VAT. A Torque Wrench is on my next wishlist.

 

Always go and look on the manufacturers website if you need part specific information or contact the importer and get the correct specifications. No general rule of thumb can be used. NEVER ASSUME ANYTHING. It can and will be a costly excersise if your stem snaps down Chappies.

Park tool torque wrenches....Handy little things.

[Christie]

The correct tightening torque depends on the bolt size.

 

If not marked, I use the following for stainless steel socket head bolts, clean dry thread, no locktite or lube):

 

M3 1.1 Nm (be very careful with these, M3 bolts are not very tough)

M4 2.4 Nm

M5 5.1 Nm

M6 8.8 Nm

 

(be very careful with water bottle cage bolts of any size)

 

You need a small and a large torque wrench to torque all the stuff on your bike. A campy casette should be torqued 50, BB 70 & pedals 40Nm.

 

Small made in Korea torque wrenches start from R400 at Screwman. I would suggest this Norbar 4-20Nm one from totalcycling.com for R826 to start with:

All my tools are Park, but I am not a fan of their torque wrenches. Norbar is a bit more expensive, but much nicer imo.
