Hutch Boss-Drive SPROCKET 39T - BLACK

Hutch 39T Sprocket is designed for 24", 26" and 29" "cruiser bike" applications such as the modern-technology 26" Trick Star, XL24, XL26, and XL29 which are designed for the 39-17 gear ratio. This sprocket includes the traditional boss-drive method similar to old-school 1980's cranks, and is compatible with the current boxed Aerospeed crank set. The Hutch sprocket's two colors have the appearance of a two-piece disc/chainring, and the holes are designed to allow you to put chainring bolts of your color choice in the 5 outer holes to enhance that appearance of the old-school two-piece design. The result is a modern version of the Hutch Aerospeed Disc and chain ring yet in a smaller 39T one-piece design.  

*note: photo shows the 25T sprocket and the 39T has the same appearance.
