A Power With Chain Ring of Bike Cranksets
A similar non-true circular convex circle, the rate of non-oval shaped circle design. In accordance with leg exert force on the crank set of mechanical distribution of curvature is R & D group development. When climbing uphill, it can reduce gear ratio & effort-saving. So that avoids the foot joints hurt, increase inertia speed. Easy achieve high-speed reding.The leg muscle fatigue reduce, thus heartbeat speed decreased, the natural increase growth distance riding.
Power of Chain Ring by Leg Force Act on Drawing of Bike Cranksets
- Muti-nagional patent applications for the golden chain ring of convex circle curvature. Professional to do the most appropriate angle degree of distribution. So do not worry to repeat do angle adjustment.
- The deadpoint shortest, & avoid foot joint injury.
- Use maxmum strength on area: Full use of muscle power for maximum riding effect.
- Increase the returm strength angle degree: To avoid oval chain reing with pedaling failure. Increase the riding safety.
