History:

Kronos Engineering's Aluminum Umbrella Head bolts are precision machined from aerospace specification Aluminum 7075-T6 on special Swiss screw machines that are used, for example, to make incredibly precise parts for Rolex, Tag Heuer, IWC, and other exotic timepieces.  Designed and engineered by an aerospace engineer and bicycle racer who knew where and how to save precious weight on the bicycle.   Weight is 1.9 grams each. Weight saved is around 6 to 10 grams a pair over typical steel bolts. Never rust and will last a lifetime.

Applications:

There are numerous applications including:

1. Cantilever brake fixing bolts - attaches to the frame mounted studs to hold cantilever brake in place.

2. Brake pad bolts - attaches brake pads to brake caliper arms

3. Fender bolts for cars - I use them on my race car to lighten up a bit and to add some color to the engine bay.
