Quick fix tips
Tune your RockShox Lyrik, Pike, Yari or Revelation fork with Bottomless Tokens
Ensure your bike is clean, to prevent dirt falling into the fork. It’s also best to hang it in a workstand. Remove the air-valve dust cap from the non-drive side of the fork (turning it anticlockwise) and put it somewhere safe. Attach a shock pump to the valve and note down the spring pressure. Remove the pump and press a slim ball-ended Allen key – or similar – into the valve to release all the air from the fork. Use a 24mm socket (or cassette lockring tool, on 2018 forks) to unscrew the air cap, ensuring that it’s pressed firmly onto the nut (anticlockwise). Remove the air cap and you should see any pre-fitted Bottomless Tokens screwed into the bottom of it. For a more progressive spring rate, add one or more tokens, by screwing them into the air cap (clockwise). Use an 8mm Allen key and 24mm socket to tighten them until gently snug (1.1-2.3Nm). Do not exceed the maximum number of tokens for your fork*.
If you want a more linear feel, remove one or more tokens, by unscrewing them from the air cap. Use an 8mm Allen key and 24mm socket, turning them anticlockwise. Ensure that the remaining tokens are tightened to 1.1-2.3Nm. Grease the air cap O-ring and reinstall the air cap in the fork, turning the 24mm socket by hand to reduce the risk of cross-threading (clockwise). Tighten the air cap to 24Nm, while applying downward pressure on the socket to avoid rounding the nut. Reattach the shock pump to the valve and reinflate the spring to your desired pressure. Push down on the fork a few times to balance the pressure in the positive and negative air chambers. Re-check the air pressure and compensate if necessary.
