Nerd Facts
The JARVIS Seat Clamp stands just 12 mm tall, with an insertion depth of 10.5 mm. Max torque: 5 Nm – laser-etched discreetly on the back.
The maximum torque is 5 Nm.
Some dropper posts require less torque, so always check your dropper manufacturer’s manual and apply the lower value of the two.
If no torque is specified, stick with 5 Nm.
How do I choose the right seat clamp size?
To choose the correct seat clamp size for your frame:
Please note: seat clamp sizes are not the same as seatpost sizes.
We recommend using a caliper to measure your frame’s seat tube outer diameter.
Or check your frame manufacturer’s specifications for the recommended clamp size.
