And here is what Shutter Precision has to say:
Technology should make life simpler and easier. SP engineers have devoted considerable time and resources to create a mechanical design strategy for overcoming some technical challenges. These efforts have culminated in an innovative mechanical design relying on super quality bearings and prevision assembly processes. Our computer aided modeling simulations indicate that we have perfected the interplay between bearing and limited internal space, making the 8X bearing assembly as durable as the time tested. The appearance treatments create the gorgeous and fine texture on the 8X. This is for personal, stylish and purpose-built bikes. The QR15 thru-axle hub is ideally suited to 26”/700C at 6V3W output and perfect for 6 bolt disc brake.
Technology should make life easier. PD-8X, a 6-bolt disc brake version of QR15 thru-axle, as an innovative hub is devised to render a clean and pure silhouette with a low weight and a sturdy construction. The meticulous design of PD-8X is able to withstand the hefty pressures produced by disc brakes while preserving a simple, clean and pure appearance.
