The new DEORE XT M8200 drivetrain features a redesigned rear derailleur with Shimano Shadow ES technology, engineered for durability and impact resistance. It has a lightweight, compact design for added ground clearance while maintaining excellent gear range with both long-cage and mid-cage derailleur options.   

Low Profile Design
Shimano Shadow ES technology delivers a wedge-shaped design that reduces the derailleur’s front-facing surface area and eliminates edges that could catch on rocks and roots.  

Super Strong Design
The rear derailleur body boasts a wide, well-braced linkage and solid pulleys to minimize debris entry and ensure durability. 

New Chain Stabilizing Technology 
With Shimano Shadow ES technology, the updated dual spring design creates higher chain tension for better chain wrap and retention. 

Rear Derailleur Options
Long and mid-cage derailleur options for 12-speed Hyperglide+ as well as 11-speed Linkglide option. 

Features:

  • DEORE XT Derailleur for 12-speed Hyperglide+

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised. That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5 Puppy pics for tax

FOR SHORT TIME USE
Size: X-Small, Color: Ring Bone
My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.

Great for our puppy
Size: X-Small, Color: Ring Bone
This chew toy has quickly become our puppy’s absolute favorite. She’s just starting to teethe, and keeping her busy and comfortable has definitely been a challenge, but this ring has been a lifesaver. She was interested in it right away and keeps coming back to it on her own, which is a huge win. The chicken flavor seems to really hold her attention, and it gives her something appropriate to chew instead of everything else. It’s the perfect size for a very young puppy and easy for her to hold and gnaw on without getting frustrated. It keeps her occupied, helps soothe her gums, and gives us a much-needed break during those teething moments. If you have a puppy just starting the teething phase and need something safe, durable, and engaging, this is an excellent choice and one I’d happily buy again.

Nylabone Ring Bone
Size: X-Small, Color: Ring Bone
My dog loves these. She chews them into pieces which helps keep her teeth clean. It is a mess to clean up. She chews and spits out the pieces. She is 6 years old so not a puppy.

Everything a Teething Puppy Could Need — Well-Thought-Out Kit
Size: X-Small, Color: Teething Bone
The Nylabone New Puppy Starter Kit is a solid all-in-one solution for the first few months of puppy ownership. It comes with multiple chew toys and bones designed specifically for teething puppies, and my little one took to them right away. The variety keeps him engaged, and I appreciate that each item is designed to be gentle on developing teeth while still satisfying his urge to chew. What differentiates this kit from other puppy chew sets on Amazon is the thoughtful selection of textures and shapes. It’s clear these toys are designed to stimulate gums, promote healthy chewing habits, and even support dental care. I also like that everything is non-toxic and durable enough to survive a few enthusiastic chews. The only reason I didn’t give 5 stars is that the kit might be a bit small for larger breeds, or for puppies that are particularly aggressive chewers. But for standard small to medium pups, it’s a fantastic starter kit that keeps both puppy and owner happy. ✅ Bottom line: A reliable, well-designed starter kit for teething puppies which is thoughtful, durable, and engaging. Makes a great gift for new puppy owners or a practical addition to your own puppy’s toy collection.
