SHIMANO RD-TY300D bicycle rear derailleur black

Shimano RD-TY300D. It belongs to the TOURNEY group and is dedicated to 5, 6, 7 and 8-speed drives. It is one of the cheapest gears on the market, therefore it is recommended for use by beginners and less demanding cyclists, but it is perfect for recreational city riding.

Characteristics:

• The Double Servo-Panta mechanism used makes the derailleur wheel in a constant, possibly close distance from the cassette sprockets, thanks to which gear shifting is even faster.

Technologies used:

Front and Rear DUAL SIS Indexed Gear Shifting

• System components such as the indexing mechanism built into the shifting lever, the frictionless SIS rear index shifting cable and the free-running rear derailleur make up the SHIMANO INDEX SYSTEM. The rear SIS indexed shifting system is also used in the front derailleur, making shifting at the front easier and more comfortable.

HyperGlide laces

• The specially designed HYPERGLIDE sprockets feature distinctive shifting ramps and tooth profiles for better chain control during shifting. HG sprockets guide the chain quickly and directly to the next sprocket without overloading. Conventional sprockets cause the chain to rise and pass over the sprocket teeth before selecting the sprocket.

Top Normal

• The top normal rear derailleurs are traditional spring-loaded derailleurs. RAPIDFIRE Plus users prefer the faster response time of the rear derailleurs as it allows faster gear changes. Cyclists for whom a quick response is more important appreciate the ability to downshift with the strongest finger, i.e. the thumb.

MEGARANGE gear ratio

• The 34-tooth MegaRange crown provides a super-low gear ratio that allows you to effortlessly pedal up the steepest slopes.
