Reverb running out of puff? Here’s how to breathe a new lease of life into it.

1. Remove saddle

Fully extend the post and remove your saddle by undoing both of the saddle-clamp bolts. We’re going to clean this mucky area, so loosen and remove the bolts.

2. Remove valve cap

Clean all of the parts of the clamp, including the bolts and the top of the post. Remove the valve cap using a 9mm socket as shown.

3. Inflate to 250psi

Screw a shock pump into place until you see the needle register pressure and then tighten a further quarter-turn. Inflate to 250psi and remove the pump.

4. Reassemble

Refit the valve cap. Give the underside of the saddle, including the rails, a clean and apply anti-seize or grease to the threads of the bolts. Reassemble the clamp and tighten the bolts (SRAM recommends 2.2Nm) once correctly positioned.
