Hydra Rear Disc HubIndustry Nine Torch Hydra Rear MTB IS Disc Hubs have way more engagement and about 20% less less drag and resistance compared to its cousin, Industry Nine's Torch. One of the first and most noticeable improvements besides those things is the easy access of the internals of the hub. In seconds, you can have internals of the hub opened up and the pawls and the drive ring right in front of you to clean and lubricate. You seriously just slide the cassette

Industry Nine Torch Hydra Rear MTB IS Disc Hubs have way more engagement and about 20% less less drag and resistance compared to its cousin, Industry Nine's Torch. One of the first and most noticeable improvements besides those things is the easy-access of the internals of the hub. In seconds, you can have internals of the hub opened up and the pawls and the drive ring right in front of you  to clean and lubricate. You seriously just slide the cassette off the body of the hub and remove it from your wheel -- isn't that crazy? You could access the internals of the freehub on the trail. If you lubricate the pawls with grease instead of oil, the sound is basically silent! Here's a video with an example of the sounds that the Hydra Torch Hub can produce:

The drive ring has 115 little teeth, (compared to 60 on the torch) and there's six pawls. 115 x 6 pawl engagement equals a total of 690 points of engagement. This is by far the highest points of engagement on the market. The pawls As soon as you go to pedal, using single pawl engagement, a single pawl is used as a fulcrum so the drive system is never relying on a single point of contact.

FEATURES:
  • Featuring Hydra internals, 115-tooth drive ring and 6-pawls, designed around a traditional flanged hub
  • Remove cassette from wheel to service hub
  • Angled flanges for lower spoke stress and large diameter disc flange improves wheel stiffness and brake torque transfer
  • Hydra freehub is a quicker engagement, is a few grams lighter, and has about 20% less less drag and resistance compared to the Torch

Not for us!
Size: Large, Color: Antler
I'm sure for a dog that doesn't chew, would be great. Ours went through it in days, leaving sharp shards and making his gums bleed.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.
