This caliper mounting bolt set from Italian manufacturer Extralite is one of the lightest available. Each grade 5 titanium bolt is machined to remove as much material as possible without sacrificing sheer strength; the threads are rolled for durability, and each bolt is equipped with a titanium washer. At a mere 9.6 grams, this set will save about 20 grams over a typical set of steel bolts. The Extralite ExtraBolt 4.5 set is compatible with post mount calipers that mount directly to the frame or fork; they are not compatible for use with rotor diameter adapters. Sold as a set of four.
Black PVD - (Physical vapor deposition) If you are wanting that stealth appearance on your rotors, Extralite takes these titanium bolts and applies a thin PVD coating to give them a sleek black look.
