Floating front ring

Abstract

A bicycle transmission system is provided herein. The bicycle transmission system includes a sprocket or ring that is capable of sliding amongst an infinite number of lateral positions relative to a crank arm. The movement of the sprocket or ring facilitates an optimal chain path from the sprocket or ring to another sprocket or ring in the transmission system and, therefore, increases the efficiency with which power is transferred through the system.

Description

technical field [0001] The present disclosure relates generally to drivetrains, and in particular, to bicycle drivetrains. Background technique [0002] Cycling is becoming an increasingly popular sport. In fact, bicycles are used for many purposes, from mountain bikes to road bikes, from single-speed commuter bikes to ultralight triathlon and time trial bikes, from cruiser bikes to downhill bikes, and more. Many advances in bicycle technology have manifested themselves in new materials for frames and components. There have also been great technological advances in the design of bicycle components such as brakes, seats, handlebars, drivetrains, etc. [0003] Most bicycle drivetrains have multiple speeds that allow the rider to select the appropriate gear ratio to suit the particular riding conditions encountered while riding. One of the most common types of drivetrain assemblies for multi-speed bicycles utilizes a chain extending between a set of front sprockets (often ca...

AI Technical Summary

Problems solved by technology

These two conditions lead to unnecessary friction on the entire bicycle drive train

Understandably, this increased friction reduces the efficiency of power transfer from the rider to the wheels
