Chain link

Wisconsin-based Trek Bicycle is introducing two new models this holiday season that replace the “finger-pinching, pants-munching, rust-prone sprocket and chain” with a carbon-fiber, whisper quiet, rust-free belt.

The new belts are a low-maintenance solution to a chain, which has roughly 3,000 parts including all the links and connectors.

Aside from the whisper-quiet ride, the lighter and longer-lasting carbon-fiber composite belts won’t rust, can’t be cut, won’t stretch or slip and won’t leave grease marks around your ankles. A guard over the belt-drive and the construction of the system makes getting your pants stuck an unlikely scenario.

One version of the chainless bike, called the District ($930), is a single-speed, complete with a silver body, orange accents and brown leather seat and handles. The other, called the Soho ($990), is an eight-speed bike that uses an internal hub to adjust the speed rather than gears.

The belt can be cleaned with a normal cleaning agent and rag, and the bike sprocket is designed to push through any snow, dirt or grime. And one belt will typically last three years — the life span of three chains. [Full story]
