The Alienation Mischief TCS (Tubeless Compatible System) rim uses Alienation's new 4D drilling process less chamfering of which; creates the optimal interface between spoke and rim. This exact angle reduces binding and the need for eyelets.

Alienation's new G69 material is super light with superior strength.

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