PBR Twin Color Aluminium Ultra-Light Self-Cleaning Hard Anodized 270 - 520 SprocketRef : PBR01010A / 1096601004

PBR Twin Color Crown Ultra-Light Mud-Resistant Aluminum 270 - 520 (ref. 270 51 TC4)

Designed for demanding riders, this PBR crown is machined from 7075 T6 aluminum, known for its strength-to-weight ratio. Its twin color blue finish and hard anodization provide surface protection while enhancing the racing aesthetic.

The tooth profile has been designed to facilitate mud evacuation and limit power loss due to friction between the chain and the crown. Strategic cutouts lighten the part without compromising its mechanical integrity, reducing the inertia of the entire transmission — an advantage for acceleration and handling.

• Material: 7075 T6 Aluminum
• Color: Blue (twin color)
• Number of teeth: 51
• Chain pitch: 520
• Type: Standard, mud-resistant, hard anodization

Suitable for Cross and Roadster environments, this crown is aimed at MX, SX, and enduro practitioners looking for a lightweight, durable, and easy-to-maintain part. Compatible with the specified engines and short ratios, it will effectively replace an original crown for those wanting to optimize the responsiveness and longevity of the transmission.
