What are the Breather Valves on Fox / Rockshox Forks for?

On the latest forks, for example Fox 38, we find breather valves on the sliders: but what are they for?


Let's answer the question straight away: positioned on the sliders, in the rear part of the legs, they have the task of "bleeding" the fork, i.e. releasing the air that could remain trapped inside the fork. Equalizes the pressure.

In the past, the most geeks inserted electrician's zip ties into the dust covers to "solve" this problem, but it could end up ruining the dust covers themselves.

WHAT PROBLEMS CAN IT CAUSE?

The air that could remain trapped inside the fork decreases the travel. This air penetration can happen if we change altitude in a short time: we take a chairlift, we do a race at high altitude (e.g. Maxiavalanche) or other situations of this kind.

The seals on the forks should insulate but, as we know, air tends to get in everywhere, thanks to the wear of the seals or the continuous changes in temperature when the fork is under a lot of stress

LEGAL PROBLEMS

Little curiosity: the 2 giants Fox and SRAM have gone to court for this technology (patent war): it's not the first time. RockShox recently adopted this system on the new forks: a system that Fox was already using. The 2 big brands are still in litigation: Fox is asking for compensation for the economic damage due to the infringement of the patent.

[email protected] I am a fan of everything that has 2 wheels: at a young age I practiced road and track cycling (Italian Allievi champion). At the age of 18 I passed into the cross country competing at national/international level as an Under23. Past Elite, I made the choice to take things more lightly from a training point of view, and my love for gravity disciplines was born, training me as an FCI MTB instructor and guide. Now I have made passion my profession by managing 2 MTB centers on the island of Elba (Bike Center Elba and Elba MTB), creating the FANTAmtb and telling in an ironic but professional way everything that revolves around MTB thanks to 365mountainbike and 365TV (YouTube'PULITI dentro BIKER fuori').
