I've put my Vorsprung smashpot into my 29 Lyriks from my 27.5.. completely silent in 27.5 but noisy knocking in the 29..my mate has a newly installed smashpot ( TF tuned) and has the same. Any advice appreciated. Thanks
Check the preload is correct, and the shrink tubing hasn't slid down. Every time I've had mine make any noise, it was those things. Running the same setup, 29 Lyrik at 180mm
