Description
A 5 pack of beautiful Alloy Chainring bolts help bedazzle the look of your race bike, while the lightweight alloy helps reduce rotating weight on your bike.Each side of the chain ring bolt has an area for an allen key for easier removal. Chainring bolts perform the simple task of securing one or more chainrings to the chainset spider, and in the case of many MTBs, a bash guard as well. While they may be another of those bike parts that most people don't notice, over time they can corrode or work loose, particularly on chainsets that have been through multiple rings. If your bolts come loose - you may feel your chainrings rattling or more likely, hear a tell-tale squeak from your chainset every time you put the power down - it's time for a new set. 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. However, bolts are available in different lengths for different applications, e.g. for single or double chainrings (a double-chainring bolt being necessarily longer than a single-ring one) Which chainring bolt is right for you? chainring bolts work by clamping the chainring to the spider and are generally marked 'single', 'double' or 'inner' in respect of how many/which chainrings they are designed to be used with. As above, single is the shorter, double the longer and some inner-ring bolts just have the male part only. However if they are too long (e.g. when a chainring is thinner than standard or the bolt is just the wrong length) they tighten against themselves rather than securely clamping the chainring or bashguard. In this instance you can file some material from the face of each bolt to shorten it, or you may need to try a size down.
