@tripleultrasuperboostplusplus: You are correct that the Hydra system does allow a small amount of eccentric rotation accommodated by flex. However, the amount of rotation is very small and that rotation essentially stops once the third pawl engages. The load is fully supported by the three pawls at this point and the materials in the drive ring, pawls, and FH body are not anywhere close to their yield point. In a traditional 3 pawl or 6 pawl phased MTB freehub, if you have three pawls engaged at the same time the load on the system is neutral. However, since there is constantly flex being introduced into the system when you are riding, it is fairly common for only a single pawl to engage in a symmetrical system. When this happens the FH is subject to large uncontrolled eccentric rotation which can cause premature bearing wear or in extreme cases, material deformation to the FH body. Our Torch MTN system was built to withstand these loads by utilizing an oversized drivering to reduce peak cantilever loads and a double row inner FH bearing with a higher load rating than most hubs on the market. However, the Hydra system eliminates these extreme stresses since the continuously phased pawls always allow the two trailing pawls to back up the initial pawl that has engaged limiting the system to a small amount of controlled flex.

We still have our full range of 29" offerings. However, the 29" wheel filter isn't quite dialed in on our new site. If you click on the 27.5" wheel filter and look at the models you are interested in, the specifications for the 29" wheels are on the product page. Thanks for your patience, while we get everything sorted out on the new site.

@miles-e: We have a revised axle/endcap for 15x110 spec only. This change aims to promote longer wear on the front hub bearings. We're no longer using a "floating" axle spacer, but rather a solid axle. Thanks!

We're on it! New site, new problems to find and de-bug! If you place the product in the cart it will give you a price. Thanks!

Not everyone is a fan of propriety parts often found on system wheels. We get that, so we offer the Hydra drive mech in our Classic platform that'll use a standard j-bend spoke.

We'll need some more details about specifically what kind of wheels you have - hit us up: service AT industrynine DOT com

We have been testing versions of Hydra for over two years in a huge variety of conditions. The system has proven incredibly durable, and all of our test wheels are still operating on their original bearings. Even though Hydra uses smaller teeth vs. our Torch hubs, since the system guarantees you will always have multiple pawls taking the drive load, it actually has a higher torque carrying capacity than our Torch product.

The beauty of the Hydra system is that it will never have just one pawl taking the full load under pedaling torque. Since the system uses a 115 tooth drivering with 6 individually phased pawls, when you are coasting, every 3.13 degrees of wheel rotation, or 1.14mm between each tooth on the drivering, yields 6 individual engagements. Meaning, as one pawl engages the two trailing pawls are respectively only .19 and .38mm away from engaging the drivering (a sheet of paper is .1mm thick). As soon as you apply torque, the natural flex inherent in the axle, freehub, drivering, and hubshell allow the second and third pawl to come into contact and share the torque load. This distributes the load in a controlled matter, which precludes premature bearing or freehub wear that can occur in conventional pawl driven systems when only a single pawl engages due to flex, vibration, or inconsistencies in production tolerances.
