With its wide range, SRAM's XX1 11-Speed X-Glide Cassette gives you a clean, simple 1x11 drivetrain. It has a 10-42 tooth spread that gives you pretty much the same gearing as 2- and 3-ring setups without the REDundancy, shifting issues and weight penalty. Yes, you can still spin up your hardest climbs. A key thing to note, is that even with the huge range, there are no huge jumps or dips in the gearing, so your cadence and pedaling stay consistent as you move up and down the entire cassette. The wide open design makes it incREDibly lightweight and aids in mud clearance, giving you cleaner shifting and longer component life. It requires an XD driver hub freebody (sold separately) that further REDuces your wheel's weight and improves the hub connection. Welcome to the future of mountain bike drivetrains.

Our award-winning REVIVE is also available as an oversized version for 34.9mm seattubes. Not only the lower tube diameter increased to 34.9, but also the stanchion tube grew form 25mm to 28mm. Finally there is a dropper that gives a stunning look in beefy seattubes while gaining strenght and stiffness at the same time. This is unrivaled by the competition. Optimized wall thickness and materials keep the weight extremely low and so our REVIVE MAX weighs in lower than some "regular" sized posts of the competition. Let´s see, what´s special about our REVIVE posts: What if there was a dropper post, that actually solves and not just improves reliability issues, saves cost and time on the long run, and does not let you worry about too much time spent at service-centers? Or how about “bleeding” your seat post within a few seconds, while it is still installed in your bike? 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 drop-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 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. So, now one might already understand that: - No external air will want go inside the post´s hydraulic circuit, since it is charged with higher pressure, than its surroundings. - No oil will go out (or at least very very little oil over the curse of a long time), because of very stable sealing - external sealing has never been a real problem of current post design - The hydraulic system can be reset to “new” via the unique “REVIVE-valving” - This means the hydraulic circuit is a very stable closed system and basically maintenance free. Still there are parts that will need to be serviced sooner or later and when designing REVIVE it was put a lot of attention to maximum user-friendly serviceability: - Bushings and keyway pins will wear over time. Usually, the pins wear first and you would want to replace them to reset your rotational play. - Exchanging the pins and the lower bushing is simple and does not require any opening of the hydraulic system and can be done within less than 5 minutes. 1 set REVIVE dropper post includes: - 1x REVIVE Seatpost - 1x cable housing 1500mm - 1x inner wire 1700mm - 2x housing endcap - 1x barrel cable clamp - 1x air valve adapter - 1x Quick-Reset-Lever - 1x remote (optional) - 1x BikeYoke I-spec adapter or Splits Clamp (optional) - 1 set titanium saddle bolts and nuts (optional)
