UP 3 Way Damper Upgrade

FAST Suspension  UP 3 Way Damper Upgrade

Product Description

Why is the Up kit your best ally?
Simply put, it’s down to its specific conception with 3 independent compression ways.

Low speed for comfort on small hits, medium speed to manage diving and balance of the bike and finally a circuit dedicated to high speed/impacts to flatten the ground.

To go even to flatten the ground. To go even further the Up kit is sold with Fast’s CELL FOAM kit to make a 100% sealed cartridge.

Get a constant dampening, emulsion free thanks to the CELL FOAM.

Customer Reviews

"Fantastic upgrade to my Yari, I get much better small bump sensitivity and less dive than with the original MoCo damper, There's tons of adjustment available with the 27 clicks on each of the slow and medium compression dials . It's super easy to install, the video is in French but still makes sense. The bleed port needs a Magura bleed nipple - I got one for £3 on ebay. "

"Game changer. Turned an uncomfortable Yari that barely used 3/4s if it's travel and spiked badly into a smooth plush fork with a ridiculous amount of grip now being generated. Wish I'd done it sooner. "

"Proper lols with that one Ash :-)! Ruth @TFT"
"I really didn't get on with the Yari before fitting the Yariup. It was relatively easy to fit the new damper, although the instruction video is in French its still relatively easy to do if you've taken a fork a part before. I used a 350ml syringe with a 6mm magura fitting in the end for the oil bleed. It was also easy to set up and get it feeling good. I've gone from a fork that blew uncontrollably through its travel, generally wallowing about, but somehow never using the full travel, to one that is nice and plush, sits high in the travel, has great small bump and in general works well. (That's the best I can describe it). It's a great upgrade, i wish i had done it sooner. "

"yes, a good upgrade, before the upgrade the Yari fork was harsh and crashed through its stroke. with the Yari up damper fittrd I can keep the fork high in its stroke with no degrading of comfort. still some tuning to go to get the comfort I want"
