Torque settins

bruce225

Got a Boardman team carbon that came with Ritchey parts all labeled torque to 5N/m, now iv'e gone and bought some Deda parts stem, seat post that say torque to 8N/m..

Thought the torque settings were to protect the carbon frame/steerer so which figures should i follow...

What figures should carbon be able to manage without any danger of damage...

After torquing a carbon seatpot up to 5nm and then undoing it with an Allen key I can safely say that I have never done metal parts up as tight as that. I never bother with torque wrenches anymore, as long as you are not using an extension bar on the key and bouncing up and down like a gorilla just tighten it like you would any bolt.

Exactly as "Smokie Joe" said, tighten it until it's tight and you know it will not move under pressure.

Good Luck

Thanks..

the last time when I went to 5N/m i was amazed how tight that was...So scared going up to 8N/m.

:oops: Buy yourself a reasonable torque wrench £30 ish. & stick with the original b/man values, torqueing is all about a repeatable value & reference point. If an item moves at 5nm. you know where you are in the " tightness scale" you can then turn it up to 6nm. After a lifetime in engineering I've seen more damage done by numties swinging on spanners & allen keys than you would believe. A little construction paste helps to keep the items in place as well as helping to reduce the chances of an item seizing to/inside another.

ive never done my team carbon parts up as high as 5nm. as said its quite tight if you have a feel for things. dont forget thats the maximum setting, not necessarily needed. my parts have never moved, must be about 3 or 4 Nm, i know because my ritchey torque key is a way off clicking. threads effectively gear things down, so the clamping force is much larger than the force on the handle.
