Description
Cush Core - XC Tire Insert Set (MTB)Cush Core XC Tire Insert Set (Bicycle) CushCore is based on a new concept: Tire Suspension. Any suspension system has a spring and a damper, and with CushCore, pressurized air in the tire is the spring and CushCore is the damper. Also like traditional suspension, a constant damping force wouldnt work. It has to be dynamic. Suspension should be supple on small bumps but firm on big hits. CushCore responds differently depending on the tire loading
Cush Core - XC Tire Insert Set (Bicycle)
CushCore is based on a new concept: Tire Suspension. Any suspension system has a spring and a damper, and with CushCore, pressurized air in the tire is the spring and CushCore is the damper. Also like traditional suspension, a constant damping force wouldn’t work. It has to be dynamic. Suspension should be supple on small bumps but firm on big hits. CushCore responds differently depending on the tire loading scenario. The more the tire flexes, the more damping it provides. We break it down into small, medium, and large tire deflections.
BENEFITS
- Smooth ride
- More control
- Less rider fatigue
- A smaller, lighter version to fit XC tire sizes and riding style
- An engineered foam insert that mounts inside a mountain bike tire. It divides the inner volume of the tire in half, with air underneath the tread and the CushCore insert next to the rim
- Absorbs impacts, reduces vibration, and adds lateral stability to the tire
- This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tires, as well as standard tubeless sealant
- Doesn't absorb sealant like other tire inserts on the market
- Includes special tubeless air valves that allows air to move through the valve without becoming obstructed by the insert

Size up, great quality
Number of Items: 3, Color: Grey/Blue/Sea, Size: X-Small
I ordered the XS and I have to say they run small. They fit my 2 year old not 6 year old. So size up. But honestly love the quality of Amazon essential shirts. I buy these for my kids pjs they are very soft

Comfy and Cool Shark Shirt
Number of Items: 1, Color: Ivory Sharks, Size: X-Small
We live near the beach, so I love finding ocean themed clothing for my little grandson. He loves this colorful swimming sharks crew neck t-shirt. He says it looks "cool." The cotton blend material is soft and and gentle against his skin. It's breathable and slightly stretchy. . The stitching is straight and consistent with no loose threads. We have fun talking about the different sharks, and the shirt looks great with his everyday jeans, joggers, or shorts. If you want some growing room, I suggest ordering a size up. The 5T is just a little long and roomy in the shoulders for my grandson who usually wears size 4. For laundering, I turn the shirt inside out and wash on cold to preserve the print. I haven't noticed any shrinkage or fading. I've been drying it on a warm setting (though cool is ideal), but I’m pretty careful not to leave it in the dryer too long to avoid wrinkles. He's been wearing it since his birthday in February, and so far, it's kept its shape, and seems to resist stains. If you have a little one that loves sharks, this check out this comfy ocean themed crew neck.

Nice quality for some basic, essential tees. The ratio cotton to spandex makes it very comfortable to wear. Great value.
