Many bike geeks prefer to attach their chainrings with Torx® star pattern bolts and nuts rather than the standard Hex/Allen key type, since they're less prone to being stripped by worn tools (the bolts, not the geeks).
- Set of four M8 x 10mm (7mm thread) Torx bolts, and four M8 x 6.5mm nuts
- Fits double chainrings or a chainring/bashguard combo
