7-speed Bicycle Gear Standardized Transmission Spiral Gear for Balance Riding
What are the characteristics of seven-speed bicycle gears?
Gear Ratios: The gear ratios determine the difference in the size
of the chainrings (attached to the pedals) and the rear cassette
(attached to the rear wheel). The gear ratios of a seven-speed
bicycle are usually designed to provide a balanced spread of gears,
allowing riders to find a suitable gear for different riding
situations.
Compatibility: Seven-speed gears are compatible with specific
drivetrain components. This includes the rear derailleur, which
must be designed to work with a seven-speed cassette, and the
chain, which should be appropriately sized for the number of gears.
Why choose us?
1.Internationally, power transmission gear devices are developing
in the direction of miniaturization, high speed, and
standardization. We are experts dedicated to high-quality small
module gears. Our factory was founded in 1994 and has 30 years of
industry experience.
2.Our company currently has one doctorate (member of the China Gear
Standardization Technical Committee) and one graduate student
engaged in bevel gear research. We have a complete set of software
for digital closed-loop manufacturing of spiral bevel gears,
specializing in gear R&D, design, strength verification and
high-precision gear manufacturing.
3.Our company has a complete set of advanced production equipment
and testing equipment such as multiple CNC 7-axis 5-linkage spiral
bevel gear grinding and gear milling machines. It has successively
developed high-quality products for users such as high reduction
ratio, high speed, heavy load, low noise, and low number of teeth,
which can meet the high-quality gear needs of industries such as
reducers, industrial robots, industrial sewing machines, and model
aircraft.
