I just purchased a
Filzer Torque Wrench (TR-1) from MEC.
I have tried it on my Cervelo carbon fiber bike but I think the torque on this wrench is not right.
This bike was purchased new, *just 4 weeks ago*, at my LBS. So the bolts
should have been set correctly.
When I set the wrench to 5.2Nm to tighten the bolts on the stem, they required one full turn before the wrench clicked. I seriously doubt that the bike shop set the torque too low.
Out of concern that the wrench is incorrect, I set it at 3Nm, 1.5Nm less than the required 4.5Nm for the seat post bolt. I eventually stopped tightening that bolt after one full turn of the seat post bolt for fear of breaking the frame. Again, I would imagine that the bike shop would have torqued the seat post bolt properly before I bought it. I have been using this bike on the trainer and the post have never slipped,so that is telling me that the bolt is tight enough.
I am not too confident in this wrench. Any suggestions on testing to see if the torque is right?
