Pick your line and let it rip. From chunky alpine terrain to warp-speed park runs, this hard-charging 29er feasts on rugged terrain, giving you the confidence to charge harder.
Race-bred suspension
Maestro rear suspension and a 170mm fork developed and tested in Enduro World Series races. The trunnion mount rear shock has a longer stroke and smoother feel, and an Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.
Progressive enduro geometry
A strong and durable ALUUX SL aluminum frameset helps you ride aggressive descents and rail corners with confidence. Enduro-optimized head and seattube angles, plus a 170mm fork with 44mm offset, produce confident front-end handling.
29er confidence and control
Larger 29-inch diameter wheels roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.

| Front Derailleur N/A | Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality. |

Nice, but easily chewed apart.
My dog loves it, but needs supervision because he can bit off bits. He's a small dog with little teeth.

JAYU PET Toothbrush Toy Dog Chew
The JAYU PET Toothbrush Toy Dog Chew is pretty cool. I used my toy poodle’s favorite toothpaste and he had a hard time really getting into the grooves. This seems like a good idea and it’s hit or miss with anything like this. My dog loved it more and tried harder when I used peanut butter. I just end up having to clean o it the grooves as he can’t get to it all. Big breeds might do better, but this is cute and could work.

Highly Recommend for Aggressive Chewers!
I recently purchased the JAYU PET Toothbrush Toy Dog Chew Toy, and it has exceeded my expectations. If you’re looking for dog chew toys that are both durable and functional, this is a great choice. My dog is an aggressive chewer, and this toy has held up extremely well without breaking or wearing down.
What I love most is how it helps clean my dog’s teeth while chewing. The textured design removes plaque and tartar naturally during playtime. It’s much easier than brushing my dog’s teeth manually, and my dog actually enjoys using it.
This dog dental toy is perfect for small and medium dogs and keeps them busy for long periods, which helps reduce boredom and destructive behavior. It’s sturdy, safe, and clearly designed with dental health in mind.
Overall, this is one of the best dog chew toys I’ve purchased—durable, engaging, and great for maintaining my dog’s oral hygiene. I will definitely be buying another one!

Not for aggressive chewers
My 14 pound puppy chewed a big chunk out within 30 minutes. Would not recommend if you have a dog that likes to tear into things

Not for aggressive chewers as labeled; poor quality
Really disappointed in this item. My barely 16 lb., 1 1/2 yr old labradoodle chewed right thru the plastic in literally 6 seconds. I was going to toss it but at $18, the item should live up to its description-this toothbrush toy is rated 80% on the aggressive chew scale as per packaging…NOT AT ALL! She bit off a couple off chunks immediately, then proceeded to bite off the spikes…couldn’t believe how quickly the toy was destroyed & I took it away within moments of giving it to her.
