WHAT IS CUSHCORE?
CushCore is 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.
Cushcore absorbs impacts, reduces vibration, and adds lateral stability to the tire. These characteristics translate to a more controlled, comfortable, and faster ride.
This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tires. CushCore is compatible with tubeless tire sealants.
A specially designed tubeless air valve is included with each insert. The air valve allows air to move through the valve without becoming obstructed by the insert.
Ideally a tire would act more like a suspension system with both a spring and a damper, where the spring supports the load and the damper dissipates the energy.
CushCore delivers that technology to tires for the first time. It is an engineered foaminsert that mounts inside a mountain bike tire and divides the inner volume of the tire in half, with air underneath the tread patch and the CushCore insert next to the rim. They work together as a spring and damper – In other words, an Inner-Tire Suspension System.
A SUSPENSION SYSTEM
A suspension system is made up tires, air pressure in the tires, springs, and dampers. This page explains the difference between springs and dampers (chassis suspension) and tires and air pressure (tire suspension).
When we think of mountain bike suspension, we normally think of suspension forks and rear shocks. This kind of suspension is designed to isolate wheel movements from the frame and rider — the wheels move up and down with the bumps and the chassis stays smooth and level. The chassis is suspended, the wheels are not.
One limitation of chassis suspension is the weight of the wheels, brakes, fork lowers — anything that is not supported by the suspension — has to accelerate and change directions extremely rapidly for the suspension to perform well.
In suspension tuning, these components are known as “unsprung weight.” Unsprung weight is bad because it delays the suspension response time. In short, the more unsprung weight, the worse the suspension.
Tire suspension has virtually zero unsprung weight. Only a tiny section of the tire deforms in response to a bump, and the mass of that portion of the tire is negligible. Because it weighs so little, it can accelerate and change directions extremely rapidly.
On the trail, this means that tires are much more efficient than a suspension fork at absorbing fast, sharp, high frequency bumps. The obstacles where chassis suspension components struggle are the same obstacles where tire suspension shines.
CUSHCORE TIRE SUSPENSION + CHASSIS SUSPENSION
The ideal suspension system is CushCore Inner-Tire Suspension paired with effective chassis suspension. With enhanced tire suspension, less compromise is required of the chassis suspension. The fork and shock may be tuned for improved stability and optimal performance on the obstacles where they naturally work best — low frequency, high force impacts. CushCore will deal with everything else.

Bigger, grippier, lighter and as tough as ever. The Penthouse Flat MK5 pedal is here!
After two years of development and testing the MK5 Penthouse Flat is here. Retaining our signature toughness, the MK5 is the lightest and grippiest Burgtec pedal to date. We did this by not only increasing the size of the pedal platform, but also how concave it is alongside reducing the diameter of the pins and adding the most wear resistant internals on the market. From the outside to the inside, we’ve sweated the details of the MK5 to bring you the ultimate flat pedal.
