Ever vigilant, Chris King Precision Components may not jump on every passing bandwagon, but they know a good thing when they see one. The Chris King ISO 15mm Front Hub with SD hubshell now brings legendary King performance to the 15mm thru axle. The folks at Chris King spent most of the past year putting the new 15mm axle standard through its paces. Apparently, they are quite satisfied with the new design, as illustrated by offering two versions of the 15mm thru axle design. This is the standard option, which uses Chris King's small diameter hub shell originally designed for use with a quick release.
