CushCore 29/27.5 Mullet Tyre Insert Kit

The CushCore 29/27.5 Mullet Kit is designed for mountain bikes running a mixed-wheel setup, pairing a 29-inch front wheel with a 27.5-inch rear wheel. It provides the correct CushCore tyre insert for each wheel, delivering greater control, impact protection and stability across demanding trail and enduro terrain.

CushCore inserts sit inside tubeless mountain bike tyres to support the tyre sidewalls and help absorb impacts before they reach the rim. This creates a more controlled, damped feel on rough ground while improving cornering support and reducing tyre roll when riding aggressively. The added support also allows riders to experiment with lower tyre pressures for increased traction without sacrificing as much stability.

The system helps protect rims against rock strikes and hard square-edge impacts while reducing the likelihood of pinch-related tyre damage. It is particularly well suited to mullet bikes used for technical trail riding, enduro racing and e-MTB applications, where additional rear-wheel strength and front-wheel control are valuable.

For riders looking to improve the performance and durability of a 29/27.5 tubeless setup, the CushCore Mullet Kit offers a purpose-built solution that enhances traction, comfort, cornering confidence and wheel protection.
