One of those parts that feels like it’s impossible to find, this 10mm diameter Campagnolo made seat bolt is the perfect size for the seat clamp lug on Alan frames and is also ideal for some early steel frame sets that required a larger bolt. The nut part of the clamp is serrated to prevent rotation and its does not have a tab. These can be carefully cut down to work with a narrower frame lug too.
- 10mm in diameter and 19mm wide between the edges once tightened
- Made in Italy
