Product description

Description:
1.There are 5 pinion bolts in the pack.
2.Made of SZ 7075 aluminum alloy/ T25 Steel
3.Has hexagonal heads both on the screw and on the nut for easy installation.

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.
