Do I need new chainring BOLTS when I get new chainrings?
Good question. Maybe.
Replace the Chainring Bolts:
– If there is any damage on the threads or on the wrench locations.
– If excessive torque was required to loosen the bolts.
– If any corrosion or rust or other malady is visible.
– If the nut and bolt feel gritty when you are tightening them together.
– If the chainring bolts appear to be too short or too long for the application.
Basically, replace the chainring bolts if there is anything that would keep the bolt from functioning perfectly now, or in the future when they need to come off. Chainring bolts are relatively cheap insurance against aggravation and frustration later. WickWerks carries several types.
You may also need to replace bolts if you are changing from a double to a single front chainring or something like that. We carry bolts for most common applications.
Reuse the Chainring Bolts:
– If they look clean and “new-ish”.
– If there is no visible damage, corrosion or rust.
Chainring bolts made of Steel or Titanium will typically last longer and can be re-used more times than aluminum bolts. They also handle torque better. Aluminum bolts are lighter and come in more colors. If the bolts look good and function smoothly, there is usually no reason to replace them.
When reusing bolts, clean them well so there is no grit or other debris that may hinder proper tightening.
