The search for the perfect dropper post is over! Bike Yoke is a small company located in Germany that have created a solution to dropper post reliability issues. Sending your post back to service centers will be a thing of the past as the post is fully serviceable at a shop/or home. 10 years of r&d went into the development of the REVIVE dropper and it really shows. Bike Yoke thought outside of the box and created a new concept, that is completely different from everything before. We have had a few riders on them for a while and are currently testing it out ourselves with nothing but positive things to say!
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 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.
The REVIVE features a NON-IFP design because they feel 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 (RS Reverb and KS LEV and Fox transfer use 4 dynamic seals), 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. 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 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. Watch the video below for an in depth look at the inner workings of this revolutionary dropper!
