Customer Reviews

"The ramp control cartridge allows you to adjust your ramp up by a quarter of a spacer at a time, without opening the fork and both make setting up the fork and test riding the fork, super easy."

"Absolutely brilliant for fine tuning, orange top looks great too."

"Great service from TF as usual! Impressed with the ramp control, with 10 psi less and 3 clicks my Fox34 Rythm feels plusher on small bumps without diving on bigger hits."

"Nice! Ruth @TFT"
"Excellent product, supplied by TF tuning, very good price and quick delivery. The ramp controller is easy to install, and the pack comes with the required slick honey for installation. The controller allows you to fine tune the progression of the fork replacing the need for tokens/volume spacers, and the need to add and remove the tokens, as this can be done on the fly with the adjustable knob. Overall excellent product and great service. Highly recommended"
