The GX Eagle Transmission derailleur is a lesser version of nothing. It delivers everything an Eagle Transmission derailleur possibly can, and then some. It features a revised battery position and a reconfigured gearbox to better protect itself from impacts. To maintain crisp shifting and striking appearance throughout its entire lifespan, hard-chargers can replace both its protective skid plates and two-piece outer link, if needed, making this the most repairable derailleur we’ve ever made. It also features the first ever tool-free cage and clutch assembly – so it’s both removable and upgradable too. With a steel inner cage that adds even more robustness, it’s been built for riders of the real world. Just like all Eagle Transmission derailleurs, it’s been engineered with a first-of-its-kind Hangerless Interface, mounting around the wheel axle itself and making direct contact with the cassette with no hanger required. The new transmission derailleurs feature the same intuitive pairing and set-up procedure as our Eagle AXS derailleurs. The revolutionary Full Mount attachment method creates a far stronger connection because it grips both sides of the frame. Let the record show that the GX Eagle Transmission derailleur plays second fiddle to nothing. It’s all in for all day. - Revised battery position, reconfigured gearbox, replaceable skid plates and outer link, tool-free cage and clutch - Install and pair via the reliable and familiar standard AXS set-up and pairing procedure - Hangerless Interface, Full Mount attachment method - Radically clear setup process, no adjustment required - AXS battery and Pod controller available separately

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.

On leg-burning climbs, crazy fast descents and rolling technical terrain, RockShox's Reverb dropper post enables you to attack the trails like never before. Just hit the hydraulic remote lever for 100–125mm of infinitely adjustable up-and-down saddle movement without ever slowing down! The return speed is easily adjustable by turning a dial on the remote while the triple-lipped sealing system and sealed hydraulic hose keep dirt out for clean, consistent operation. There's also an included collar that limits travel to a preferred height setting. So go ahead and drop your seat a couple of inches for that 30-foot technical section, raise it for that long climb then lower it all the way and get back for that steep descent, without losing your flow.

New Super Record 12 Speed sprocket cassettes: innovation which gives the user great advantages, thanks to the matching dimensions and complete compatibility with wheels and frames. The rider has always been Campagnolo’s focus, and the goal has always been facilitating their performance; making the impossible possible. Adding an additional sprocket might seem simple, however, we have not only succeeded in maintaining the same footprint, but also improving the component’s performance and durability, which was a tricky challenge! The new Super Record 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets, meeting everyone’s needs with just two (11:29; 11:32) cassettes. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist to find the perfect ratio for any situation. In addition, the closer sprockets ensure faster, quieter and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer lifespan. The 6 larger sprockets are also available in two single-piece steel triplets, to avoid energy loss. Mounting the cassettes is easy thanks to matching-thickness spacers.

BSA is another way of stating English threading. The initialization comes from Birmingham Small Arms, which made bicycles. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit works with 24mm diameter cranks, found on cranks from Shimano, FSA, Rotor, and others. Choose between two bearings for the cups. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. 24mm spindles easily fit through the shell and allow for large bearings to be employed in the outside cups. Put more of your energy into forward motion by reducing frictional drag wherever you can. CeramicSpeed Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction compared to standard bottom brackets. CeramicSpeed balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings. In The Box: - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10mm syringe of All Round Grease - Sticker sheet

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)

Mirror goes Pro. Our best-reviewed saddle technology, based on two decades of Body Geometry research and development, is now available on the Power Pro saddle. Looking beyond foam, we developed Mirror technology. By 3D printing with a liquid polymer to create an infinitely tunable honeycomb structure, Mirror saddles perfectly reflect your anatomy to keep you comfortable, powerful, and healthy in your unique position. The Power Pro with Mirror starts with our Power shape—beloved by riders worldwide for its extra-wide and elongated Body Geometry channel—and is topped with the exact same Mirror pad as our S-Works Power with Mirror, a patent-pending matrix of 14,000 struts and 7,799 nodes, each of which can be tuned individually to deliver unprecedented sit bone comfort and soft tissue protection. But our Pro-level saddle features titanium rails and a reclaimed carbon fiber base to bring Mirror technology to more riders on more terrain than ever before. The bike may be the most sustainable transportation ever created, but we need to do more. The saddle's carbon base is built with our all-new reclaimed carbon process. This is our first step on the road to closed-loop production, maximizing efficiency in production and minimizing waste. Using carbon scraps from factory production, combined with injected nylon, we're building a more sustainable carbon base. With the Power Pro's titanium rails, Mirror technology is now more durable than ever. It's so strong that our Mirror technology is now trail-ready, so go ahead and huck that gap. Trail riders have sit bones too, after all. Whether you're on the road or trail, going up or down, the Power Pro with Mirror will get you there comfortably and quickly. It's the perfect reflection of you. - Titanium rails. - Mirror technology utilizes 3D printing from liquid polymer to create a one-of-a-kind honeycomb structure that offers superior sit-bone support and comfort. - Reclaimed carbon fiber and nylon-injected base. 15% reclaimed carbon fiber. - Patented Body Geometry design is lab-tested to ensure blood flow to sensitive arteries. - SWAT™-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Approximate weight: 251g (Size 155mm) - Approximate weight: 245g (Size 143mm)

The Romin EVO Pro with Mirror starts with our Body Geometry methodology and combines this with our game-changing Mirror saddle technology to create an unmatched combination of performance and comfort. The saddle is designed for riders that prefer an agressive, performance inspired position that still protects soft tissue and blood flow. The result? 26% less pressure, right where it counts. PERFORMANCE MEETS COMFORT: The new Romin EVO Pro with Mirror saddle uses the exact same 3D printed pad as the S-Works Romin EVO Pro with Mirror but now comes with a nylon and reclaimed carbon fiber shell and hollow Ti rails. Our Romin EVO has been a favorite for our professional athletes and racers everywhere season after season. Its traditional long shape is designed to relieve pressure in aggressive, race-inspired positions while allowing the rider to slide backward and forward on the saddle to provide the ideal position for tempo climbing or maximum wattage efforts. Now with Mirror technology, the saddle reduces pressure by up to 26% compared to traditional foam saddles, validated with extensive high-resolution pressure mapping studies. It uses a 3D printed matrix with 22,200 struts and 10,700 nodes and features a unique concave shell to deliver our thickest Mirror pad yet. To ensure your fit is dialed, it comes in two widths: 155mm and 143mm. BODY GEOMETRY AND MIRROR: We know that every body is different, but the issues facing riders in the saddle are the same — sit bone pain, scar tissue build-up, and blood flow loss. Using pressure mapping, blind comfort studies, and even penile blood flow studies (yeah, we did that), Body Geometry and Mirror Saddles don’t just promise to solve these issues for men and women — we’ve proved they do. Unlike traditional single-density foam, Mirror technology allows for infinite density tuning with a single material. But any material is only as good as the designers and engineers that use it. Thanks to our Body Geometry methodology, Retül data, and decades of experience, the 3D-printed matrix is tuned to support the sit bones across a greater area, creating a hammock effect that lets the saddle support your weight, not the tissue around your sit bones. DURABILITY AND SUSTAINABILITY: By using reclaimed carbon fiber in the shell, we’re keeping scrap carbon fiber out of landfills while creating a light and durable saddle. Add to this hollow Ti rails, and you’ve got a saddle light enough for performance road and XC riding - just 243 grams in a 143 mm width — and tough enough for gravel and trail riding. - Patented Body Geometry design is lab-tested to ensure improved comfort and blood flow to sensitive arteries. - Mirror technology pad features 22,200 struts and 10,700 nodes, all individually tuned. - SWAT™-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Lightweight and durable hollow Ti rails. - Reclaimed carbon fiber and nylon-injected base. 15% reclaimed carbon fiber. - Size 143mm / Weight: 239g - Size 155mm / Weight: 245g
