At Link, we think a little differently. Especially about gears. While some folks like their gears to be out on display, we prefer to tuck our gears away.
Rain, mud, and snow. No problem. Our gears don't know a thing about it. That translates directly to more ride time, less maintenance. Regardless of riding conditions or weather, you can just pedal...and shift without a second thought. Your bike will always shift.
Internal Gears: Improved Durability & Reliability
We offer a full complement of internal gear solutions, from a 2-speed crank up front to four different internally-geared hubs in the rear. These components replace conventional shifting systems and put all the gears and shifting mechanisms on the inside. Typically, this is achieved through the use of a planetary gear system. Simplified, a "sun" gear at the center drives a series of planetary gears. The size of the sun vs. the planets sets the gear ratio and determines how easy or how hard you have to pedal.
This internal gear system is encased in a sealed metal shell and typically runs in an oil bath or grease. These well-engineered systems are protected from the elements and require no external adjustments. The upshot is that you'll benefit from reliable shifting and longer component lifetime.
