How tight should seatpost clamps be?

How tight should seatpost clamps be?

Yes, ANY bolt/nut can be overtightened. Zinn recommends 106-140 inch-pounds (~8-12 foot-lbs) of torque for the seat tube binding bolt, for what it’s worth. However, I agree with Kerry. Better to UNDER-tighter and find out when your seat slips a bit, then OVER-tighten and have big problems.

How much torque should a saddle have?

Generally between 5 and 8 nm.

Do you grease seatpost clamp?

Yes, grease at all metal to metal contact (especially important with Fizik Cyrano seatposts).

How tight do you tighten carbon seatpost?

A carbon post does not have this problem and should not be greased. Follow the torque recommendation for the post. If it slips, tighten 1/4 turn at a time until it doesn’t slip any more. Carbon posts most certainly can react with the metal of a frame and become badly stuck.

How do you tighten a seatpost without a torque wrench?

As for torquing without a torque wrench, hold the allen key with one finger and use your whole arm movement to tighten the bolt. When the finger holding the allen key begins to extend under the tension, it’s torqued adequately.

How tight should pedals be NM?

Shimano says to torque pedals to 35–55 Nm after greasing the threads. I don’t have a torque wrench that goes that high, but my best estimate is that the upper end of that is pretty darned tight; probably far tighter than many pedals are fitted.

Can I use chain lube on seatpost?

Greasing your seatpost will prevent problems like this: “Removing Seat Post rusted into downtube”. Don’t use chain oil, grease is what you want. As whatsisname pointed out, all fasteners on your bike should be lightly greased. This is what keeps them from corroding and seizing over time, becoming a real pain to remove.

Should you grease seat tube?

You should grease your seatpost on the segment that fits into the seat tube to prevent oxidation and corrosion. Grease also prevents jamming of the seat post in the seat tube and gets rid of creaks. Instead of grease, you need a carbon assembly compound that prevents slipping and corrosion.

How tight should lug nuts be torqued?

The general rule for steel wheel lug nut torque is usually around 80ft/lb, and for aluminum wheels it is around 100ft/lb, this being said you still need to check on the manufacturer’s specifications. Drive safe and secure, get your wheels checked.

How much torque should I set on my seatpost?

Never exceed 6 Nm, and if you are using a carbon seatpost or a dropper post, you may have to set it at a much lower measurement to prevent any crushing or binding of materials. Now that the torque is set, you shouldn’t have to retorque it again unless you install a different seatpost.

How do I torque my QR Seatpost clamp?

If it isn’t already, flip the lever on the QR Seatpost Clamp closed. You may have to loosen the bolt on the clamp if this is not easily done. Using your frame and/or seatpost torque specs as a guide, use a 4mm hex torque wrench to set the torque.

What size clamp do I need for a Seatpost clamp?

The seatpost clamp should match the diameter of the seat tube on your frame and not the diameter of the seatpost itself. WARNING Handling this product will expose you to chemicals, including lead, known to the State of California to cause cancer and birth defects or other reproductive harm.

What is the correct torque for a seatbolt?

There is usually quite a range of values quoted. For my Planet X carbon the seatbolt torque is 5.8 – 8.0 Nm. It is secure at 6 and hasn’t moved in several hundred miles. Thanks guys, mine is at 6 and doesn’t move at all though from the wildly differing settings I’ve heard/read, I even wondered if that was over tight?!
