This replacement idler gear is designed for our R1WURKS B7 3-Gear Transmission. It can also serve as a universal upgrade for other applications requiring a 48 pitch, 39T gear.
Key Features and Specifications:
These gears can serve as a direct replacement or upgrade for the Team Associated® part #91716. Compared to the original, these gears offer reduced friction and decreased rotational mass due to their narrower 8mm profile.
