We use strong and hard 7075 alloy to make the Prime alloy chainring bolts to make sure they are tough enough to keep your rings securely attached to your bike. These rings are all individually CNC machined to ensure a precise fit. At only 9.5 grams per set, they help you drop a little weight over steel bolts. These bolts come in a choice of four colours.

Features

• Weight - 9.5 g / set
