I used them on a steel frame tandem for 2 years. Our daughter used it from age 5 to 7. Easy to install. Sticks like welded.

How tight do you tighten this? Nm/foot lbs?

Hi there,

There are no provided torque measurements with this product, we recommend that you carefully evenly tighten the product until it is snug - of course be vigilant to making sure the clamp is closing evenly and no causing any damage to the frame.

How Tall Is This Product?

i.e. how much of the seat post does it take up.

Is the BB central (both vertically and horizontally)

The clamp takes up 80mm of the seat tube. The bottom bracket is mounted in the centre of both dimensions.
