RocRide Single Chainring Bolts
RocRide Chainring Bolts are a set of 5 bolts that can be used on chainrings requiring 4 or 5 bolts. These bolts have a 7mm thread depth and a 10mm external width, making them suitable for hole depths of 5-9mm. You can choose between durable steel bolts for a classic look or lightweight anodized aluminum bolts that match your chainring color. The aluminum bolts are made from aircraft-grade 7075-T6 aluminum, which is strong and lightweight, weighing only around 1.5 grams each. On the other hand, the steel bolts provide rugged durability and weigh around 4 grams each. It's important to note that the steel bolts may not be long enough to add accessories like bash guards to the chainring, for which you would need double or triple width bolts. These 2-piece design bolts require a standard chainring bolt wrench for installation or tightening, and we recommend tightening the steel bolts to 12Nm.

Frequently Asked Questions (FAQs)
1. Do all chainrings fit all cranks?
Are they interchangeable? Largely speaking, yes. As long as your attempting to replace them with a chainring(s) designed to work with your chainset. Your cranks will have a specific bolt layout or fitment spec so you can't just fit a BMX chainring to your triathlon bike.
2. Are all chainring bolts the same size?
Single bolts are generally between 3.5 – 5.0mm Long. Double bolts are generally between 5.0 – 6.5mm long. Triple bolts are generally 7.0mm or longer. Triple bolts are normally only used to hold the two outer chainrings as the inner will be smaller and screwed directly to the crank.
3. Are all chainring bolts the same?
Each chainring bolt – the number will vary depending on the chainset design, but is usually four or five – consists of two parts, a female-threaded 'outer' part and a matching male 'inner'. The outer nut has a standard external diameter of 10mm so theoretically the bolts can be used to fit any chainset.
