Which way do chainring bolts go?

Remove chainring bolts Secure the nut and unscrew the bolts in an anti-clockwise direction. Remove the bolts, taking care to keep them safe for installation of the new rings.

What size are Shimano chainring bolts?

Outer diameter of male bolt across threads is 7.7mm, outer diameter of female sleeve/nut is 9.6mm. Diameter of both across the pan head is 11.6mm. These are the measurements for a Shimano 5700 compact crank 50/34 stock chainrings, for future reference.

Are chain ring bolts universal?

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.

How tight should chain ring bolts be?

A Shimano “General Operations” manual states the tightening torque for road chainwheels is 12-14 N-m. For mountain bike chainwheels it’s upped to 14-16 N-m for large and middle ring and 16-17 N-m for the smallest ring of a triple.

Can I change chainring without removing the crank?

Changing rings is not that difficult, and in some cases, it’s possible to replace chainrings without removing the crank. That possibility is limited by what ring sizes you’re using, but hey, it’s always nice when you can work smarter not harder. This trick works for most road cranks and some mountain cranks.

Should I grease chain ring bolts?

Be sure to apply a little grease to all surfaces of the chainring bolts (both halves and the threads). That’ll ensure you get them tight and make it easier to get them off the next time you do this job. Also, it help prevent any annoying clicking when pedaling. Don’t overtighten aluminum bolts or they can break.

Are all chainring bolts the same size?

Chainring Bolts come in many different lengths and are often referred to as single, double or triple which a rough guide only. 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.

Should you use Loctite on chainring bolts?

Chainring bolts don’t need much torque and they rarely come loose (i’m inclined to say never). Loctite will just make removal more difficult, and generous coat of grease will prevent corrosion just fine in practice.
