Frequently Asked Questions (FAQs)

1. How do I keep my bike seat from sliding down?

Using your finger or a brush, apply a thin coat of new grease to the inside of the seat tube, or the outside of the seatpost. Re-insert the seat post to your preferred height, and clamp it in place. Use standard bicycle grease if your frame and seatpost are both any kind of metal (steel, aluminum, or titanium).

2. What seat clamp size do I need?

Note: The seat clamp diameter needs to match the diameter of your seat tube rather than your seatpost, which is a little smaller. For example, a 27.2mm seatpost (a size commonly found on road bikes) fits inside a 28.6mm diameter seat tube, so it's a 28.6mm clamp you need.

3. How do I stop my bike seat from moving left and right?

Nut and Screw Hold the bolt in place with a screwdriver and turn the nut counterclockwise. Move the seat to the proper height and tighten the nut. Avoid tightening it fully until you evaluate the seat height. Once you are comfortable with the adjustment, tighten the nut fully.
