Who has cycle specific torque wrench?

I am a recently returned cyclist. When I left carbon was pretty exotic. My new bike has a carbon seat post and specific Nm of torque to se the bolt to. I have a car torque wrench, much higher Nm settings. Who has purchased a bike suitable one?

I have a carbon seat post but also interested for other things like stems. Also when I need to start servicing the bike.

Recommendations?

Yep, seat posts, stems, bars, all the bits you really really dont want breaking due to over done nuts and bolts (or any time for that matter, but certainly for things that could be avoided).
Interesting to see a lot of Pros still use alloy gear in the cockpit, considering they could have whatever lightweight bling they wanted, i guess they still see value in strength rather than the cool factor

I have this one too. A must have if you own a carbon framed bike imo.

For those wishing to calibrate a torque wrench, it can be done accurately at home. With a suitable driver, such as a male square drive fitted in the wrench, clamp the square drive in a vice so that the torque wrench is in the horizontal position, Then, at the other end ( usualy a knob of some sort ), hang a weight of a known value, which would be equal to a particular torque load. The weight to be used that is equal to a given newton metre value can be found by Googling that conversion. 

The above may sound a bit involved, but it really is quite simple, and is basically the same as is done in mechanical engineering works.

As a matter of interest, in the aircraft industry, the answer to the question of "how often is a torque wrench calibrated"? The answer is " before use" !

Sounds like the same LAME's who serviced a Sikorsky S92 that had to make an emergency landing an hour out Broome WA en route from an offshore oil rig I was working on. Three of the  four bolts holding the cover on an oil filter just below the rotors sheared off mid flight. The cover was hanging on by one bolt when they put the chopper down on land having just flown for an hour over water. The main rotor gear box also dumped its contents over the tail boom of the aircraft...luckily the gear boxes on these machines are military rated and can run for a bit without oil in them.
