Chainring - 110 x 40t VUELTA - 12015
All the chainrings we sell are for 110 x 74mm bolt circle diameter cranks. This classic size is now popular with old mt bikes and many new road bikes alike.
Made in the USA by Vuelta/Origin8 aluminum chainrings.
Middle ring 110 mm bcd (bolt circle diameter) x 40t. Bolt-on replacement for our wide-low crank.
All are silver with no ramps or weird shaped teeth or pins. Absolutely nothing fancy about these rings. Plain and simple looking rings at good prices.
Here's a neato tool to keep that chainring nut from spinning round and round.
