Details matter. Especially on a bicycle. From the cable stops to even the seat binder bolt. If anyone knows about this, it’s Richard Sachs:

“The RS Seat Lug Bolt and Nut are precision machined from aerospace grade stainless steel solid bar stock. The pitch diameter of the bolt was held to a super precise tolerance prior to cold forming on dedicated thread rolling equipment. Rolled threads result in a part that is 30% stronger and has a superior surface finish. The care put into this one component demonstrates that whether you are making parts for airplanes, or for bicycles, the details matter.”
