BikeYoke presents the REVIVE dropper post, featuring one of the most brilliant design features in dropper post design in many years. More than 10 years of experience in dropper-post design went into the “REVIVE” and the development has finally paid off. Of, course, just as many other companies, BikeYoke would say, that REVIVE is reliable and strong and smooth, … And yes, REVIVE is all of that, but not because we tried to improve current designs, but because we were thinking outside of the box and created a new concept, that is completely different from everything before.
To understand the benefits over other posts you have to know about the problems of many current designs first: Many of the popular current seatpost designs are based on a hydraulic lockout-system that relies on a perfectly sealing IFP (Internal Floating Piston), separating oil from air to prevent the seatpost from getting sagging or bouncing. There are a lot of difficulties to overcome when using an IFP, because an IFP has to maintain 100% sealing function. If air could go to the oil side, your post will start becoming springy. This happens to a lot of posts in the market already and is the main issue why posts need to be serviced.
That´s why BikeYoke´s “REVIVE” features a NON-IFP design, because we think it is too difficult - if not impossible - to make a really reliable design using an IFP. REVIVE only requires 2 dynamic seals in the hydraulic circuit: The shaft sealing and the main piston sealing for the lockout mechanism. The highly critical IFP has been removed, and with it the need of perfect concentricity and finish of the sealing surfaces of the tubes. The lack of an IFP also results in the smoothest action you can think of.
The most important and ground-breaking feature of the Revive is its “REVIVE-VALVE”. Even REVIVE can get air somewhere where it does not belong. This can happen for example when you actuate your seatpost while its upside down. And here is where the patented RESET VALVE comes into play: Insert a 4mm Hex Key into the REVIVE hex port, turn it and push down the post by hand. This will reset your hydraulic circuit on the fly - whenever. wherever. This is done just within a few seconds and only by the turn of a 4mm Allen key or the integreated mini reset lever, that comes with the post - of course without even having to remove your drop post from your bike.
