Tier 1 Components Carbon Racing Rims are engineered for riders who demand exceptional stiffness, low rotational weight, and race-proven durability. Manufactured from premium Toray T700 carbon fiber using advanced molding techniques, every rim is designed to deliver consistent performance on the gate, through corners, and across the finish line.
Whether you are chasing your first win or competing at the highest level, Tier 1 rims are built to perform under the demands of modern BMX racing.
Every Tier 1 carbon rim begins with genuine Toray T700 carbon fiber, selected for its exceptional balance of strength, stiffness, impact resistance, and lightweight performance.
Our manufacturing process creates a rim that delivers responsive acceleration, precise handling, and excellent power transfer while maintaining the durability required for BMX racing.
The Tier 1 rim profile has been engineered to maximize strength while minimizing weight.
Its 38 mm deep-section design increases lateral stiffness for improved cornering stability and efficient power transfer while maintaining a lightweight race-focused platform.
The internal structure is optimized to distribute spoke loads evenly across the rim for increased durability.
Tier 1 Components offers multiple carbon weave and finish options depending on product configuration.
Depending on the model and selected configuration, Tier 1 carbon rims are available for either rim-brake or disc-brake use.
Models equipped with a basalt brake track provide improved heat resistance, consistent braking performance, and enhanced durability during prolonged braking.
Every rim is manufactured using precision molding techniques and strict quality-control standards.
