The Hope Tech 4 Evo GR4 is Hope's most powerful four piston brake, perfect for DH, enduro, and e-bikes!

- Exchangeable EVO lever blades feature an increased hook for greater control and security and a new dimple design in the contact area improves comfort while retaining grip
- A bleed port has been added to the master cylinder body to allow bleeding without removing the lid

Just what I was looking for to slow my large dog while eating
Size: 1 Pack, Style: Pawbler, Size: 1 Pack, Style: Pawbler
I needed something for my 50-pound dog to slow down her eating. The usual slow-feeder bowls and mats weren't really slowing her down much and I wanted her to have to think a little bit. She's not smart enough for puzzles though. So I got this kibble dispensing toy. My dog is not a chewer so I don't have to worry about her destroying it.
LOVE: holds a little more than a cup of kibble, dispenses different sized kibbles, heavy weight so it wobbled around a lot without going too far away, QUIET- I couldn't bear the noise of hard plastic dispensers clacking around and this one is very quiet on our hardwood floors, kept the dog busy for at least 20 minutes. It's really all I was hoping it would be. And, well, as you can see in the video, the cat is happy about it too...
As with all of these dispensers, there will be a couple of kibbles left inside that are hard to get out. But that gave my dog something to do overnight. She spent a long time getting that last kibble out. The slight scent they add to the natural rubber is not a problem at all. This dispenser is absolutely worth the money, it's going to last us a very, very long time.

People are doin it wrong
Size: 1 Pack, Style: Cone
Cheap and durable and huge. The bad reviews are from people who aren’t using it right. Step 1) plug hole with a smear of peanut butter. 2) put a low calorie but appetizing mix of whatever you want: yogurt, pate, pumpkin puree, blended with frozen veggies on the walls 3) freeze cone for 30 mins. Hole will be sufficiently plugged to add liquid. 4) fill the rest with water or bone broth and freeze overnight to make it a changing ice block.

Durable
My dogs love this one so much that we had to order another one so they wouldn't fight over it. They usually destroy toys in less than a day, but this one has lasted months now.

Determined Chewer Approved
Durable, but not impenetrable! My 68lb Lab got this in the mail today and happily chewed on it for around an hour non-stop. She is a strong and determined chewer, but not a super chewer. She destroys "moderate" rubber chew toys in a flash, but doesn't like hard nylon chews, so finding a rubber chew that can withstand her dilligent gnawing and suit her preferences is a rarity. This one absolutely is a win! The material is most similar to nylabone's Rhino rubber (compared to the Crazy Ball), and with time and continued chomps it will sustain damage, but for my dog (strong, not super chewer) it takes a lot of time to wear out and the early breaks are tiny like specks of sand. It's a safe choice for my dog, and she loves the texture of this toy!
