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

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
