Our take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.
Forget shortcuts—this bike even makes detours fun. The Topstone Carbon 1 AXS is packing SRAM's Rival AXS XPLR 13-speed wireless shifting and KingPin suspension to keep you rolling over roots, rocks, and whatever else the trail throws your way. Reserve 40|44 carbon wheels don’t just keep up; they thrive on thrashing. Adventure never looked so good.
What it's for: Gravel riding & racing, bikepacking, going hard and long on dirt or pavement
FEATURES:
- Smiles for Miles: Kingpin is our lightweight, go-for-longer rear suspension. Maintenance-free and complexity-free, it gives the Topstone frame legit rear-wheel travel without compromising stiffness for the sprint. Kingpin provides a smoother ride, more traction to push harder, and more give to take on the rough stuff. You’ll hardly know it’s there, but you’ll be very glad you’ve got it.
- Bring It All: Our all-new StashPort storage system in the downtube is designed to be concealed yet convenient. Paired with the special StashBag, you can bring your essentials along for the ride and know that they’ll be kept safe, whatever you get up to out there. Meanwhile, multiple mounting points on the frame, mean more gear and more adventures.
- Tuned Ride: A dialed-in ride, just for you. AKA: Proportional Response Construction. Everything from the carbon layup to the geometry on Topstone is individually tuned by frame size. So that the bike – including KingPin suspension – works in harmony to give you the best ride for you and your dimensions.

Durable!

Alright, here's a product review for those Tough Dog Toys:
Finally, a Toy That Survives My Monster! - Tough Dog Toys Review
As the owner of a determined (and I mean determined) large breed chewer, finding toys that last longer than five minutes has been a constant and often frustrating quest. I've gone through countless plush toys ripped to shreds, rubber toys with chunks missing, and even some "indestructible" toys that met their demise far too quickly. That's why I was both hopeful and skeptical when I came across the Tough Dog Toys, designed specifically for aggressive chewers and large breeds.
Let me tell you, these bone-shaped nylon toys are living up to their name. My power-chewing Labrador has been going at this thing for days now, and I'm genuinely impressed. Where other toys have succumbed to his relentless gnawing, the Tough Dog Toy has held its own. There are some minor teeth marks, as expected, but absolutely no significant damage, no pieces torn off, and no signs of imminent destruction. "Almost indestructible" might actually be an understatement!
The design is simple but effective. The solid nylon construction feels incredibly durable, and the bone shape is easy for my dog to grip and maneuver. It's also a good size for a large breed – substantial enough that he can really get a good chew going without it disappearing in his mouth.
What I appreciate most is the peace of mind this toy provides. I no longer have to constantly supervise playtime, fearing that he'll ingest pieces of a destroyed toy. This feels like a safe and long-lasting option for even the most enthusiastic chewers.
Pros:
* Truly durable – stands up to aggressive chewing from a large breed.
* Solid nylon construction feels virtually indestructible.
* Safe design with no small parts to break off.
* Good size and shape for large dogs to grip and enjoy.
* Provides long-lasting entertainment.
Cons:
* May show some teeth marks over time (though this hasn't compromised its integrity).
* It's a fairly hard material, so dogs who prefer softer toys might not be as interested.
Overall:
If you're at your wit's end trying to find a toy that can withstand your aggressive chewing large breed dog, I highly recommend giving the Tough Dog Toys a try. This bone toy has proven to be the most durable option we've encountered, offering excellent value for money and, most importantly, a safe and engaging chewing experience for your furry friend. Five out of five paws!

Very well made chew bone!
Color: 1 PC-Beef-Red
Great durable, very well made chew bone! Our dog usually tears up all his toys within a few minutes or sometimes hours after he gets them. He’s had this bone for a few days and it’s still in one piece. Except for the rubber that’s in the middle, he chewed up in a couple of days. I would definitely buy more chew toys made by this company! Well worth the money!

The rubber middle is not durable, it lasted less than 3 hours.
Color: 1 PC-Beef-Red
I bought this as I have bully/husky puppies (9 months old) and a pitt/doberman (9 years old). They are heavy chewers and destroy everything. I saw a video of this toy. The woman said that her dog chewed on it for a while (about 2 hours or so) she showed the ends visibly chewed, which I expect but it was holding up. The rubber middle seemed to hold up to. I received this yesterday. I had to take it away from them last night as they were chewing the rubber middle off. They had it maybe 3 hours. I didn't give it a lower star score as I will just cut the rubber off and give it back to them. So I was disappointed in the rubber middle not being more durable but the hard plastic it's made from is the strong material they need.

Smaller than pictured but still a good choice for LG-XL dogs/power chewers!
Color: 3 PC-Beef-Red, Color: 3 PC-Beef-Red
Fantastic that these come in a 3 pack - I wish more chew toys did this! The base for these chew toys is pretty tough! The center & ends are hard enough to withstand both my bully mixes & my Irish wolfhound/Great Dane cross. They’re safe enough for even the largest power chewers! (With Supervision) my American Bully got the rubber spikes chewed off in under 20 minutes which is mildly disappointing but he’s a true powerhouse & master destroyer of all chews so I’m not that bent out of shape about it. I do wish they were as large as they appear in the ad pics but isn’t that the game we all play ordering offline anymore? 🤷🏻♀️
• Pro Tip: smear this toy in peanut butter (xylitol free!), wet food mixed into a slurry with water or bone broth + kibble/treats, yogurt, or even pumpkin puree and freeze for a few hours & relax while watching all the organic engagement your dog gets out of this toy!
