Alienation OS20 Rim (Black) (36H) (Schrader) (OS20) (1.75″)

The Alienation BMX OS20 rim is constructed from 6061-T6 aluminum with a double-wall design, pinned seam and machined sidewalls for a flat braking surface. OS20 rims have an oversized bead diameter at 451mm allowing them to roll faster and smoother than standard 20×1.75″ rims while also being perfectly legal in the 20″ race class.

Note: Designed for OS20 frames only. Requires use of OS20 specific tires and OS20 or 20×1-3/8″ tubes.

The advantages of OS20:

• Rolls faster and smoother over bumps
• More stable at speed and in the air
• Larger contact patch for more traction off the gate and higher lean angles in the turns

The disadvantages of OS20:

• Slightly higher rotating weight
• Small adjustment period getting used to the way the larger wheel responds to rider input
