Abstract
A bicycle drivetrain includes a front crankset having an axle, a main rider, a glider, an outer mesh plate coupled to the main rider, an inner mesh plate coupled to the glider that is configured to move toward and away from the outer mesh plate, and a spring configured to bias the inner mesh plate toward the outer mesh plate. The bicycle drivetrain also includes a rear cog and a hybrid chain connecting the front crankset and the rear cog. The hybrid chain is configured to mesh with the outer mesh plate and the inner mesh plate.
Claims18
A bicycle drivetrain comprising:
- a front crankset comprising:
- an axle;
- a main rider on the axle;
- a glider on the axle;
- an outer mesh plate coupled to the main rider;
- an inner mesh plate coupled to the glider, the inner mesh plate being configured to move toward and away from the outer mesh plate;
- and
- a spring configured to bias the inner mesh plate toward the outer mesh plate;
- a rear cog;
- a hybrid chain connecting the front crankset and the rear cog, wherein the hybrid chain is configured to mesh with a pattern on each of the outer mesh plate and the inner mesh plate;
- and
- an index shifter coupled to the glider with a cable, wherein movement of the index shifter to select a lower gear causes the cable to pull the glider and the inner mesh plate away from the main rider and the outer mesh plate and compress the spring.
