BikeYoke presents its new REVIVE dropper post, featuring one of the most brilliant design features in drop post design in many years. More than 10 years of experience in drop-post design went into the “REVIVE” and the development has finally paid off.
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.
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 suspension feeling. There are a lot of difficulties to overcome, when using an IFP, because an IFP has to maintain 100% sealing function. If air can 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.
Thats why “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, with those two seals being the ones, that are known to cause the least problems in sealing application: The inner shaft sealing and the 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 of any hydraulic drop-post on the market.
The most important and ground-breaking feature of 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 for a few times, while its upside down. Insert a 4mm Hex Key into the REVIVE hex port, turn it and push down the post by hand. This will automatically reset your hydraulic circuit to “new”. Whenever. Wherever. This is done just within a few seconds and only by the turn of a 4mm Allen key, without even having to remove your drop post from your bike.
Revive droppers have comparatively few parts and are designed to be rebuilt by an average home mechanic using simple tools.
