Okay, I have just bought a new 25mm setback FSA seatpost and was going to buy a torque wrench to go along with it. I have already in my possession a 5nm Torque Key but I need 7nm for the seat clamps. The problem is that despite finding a reasonably priced wrench, there doesn't appear to be a fitting that will reach the bolt in the recess of the seat-post. Does anyone either have any idea where I can find such a fitting, whether or not they exist or should I torque it with my existing key to 5nm and give it a little tighten manually? What do you all reckon?
