The Alienation Malice TCS (Tubeless Compatible System) uses the most advanced drilling pattern of any bicycle rim on the market today. Alienation's new 4D drilling process creates the optimal interface between spoke and rim. This exact angle reduces binding and the need for eyelets. The I-Beam is distinctive, centrally located vertical support counteracts spoke loads and provides torsional rigidity. Our new G69 material is super light with superior strength.

Note: These rims are designed and drilled for 3 cross specifically. Each TCS Malice rim comes with a valve plug for the unused valve hole (TCS Malice rim drilled for both TCS and Schrader).
