High tensile steel
*The material of high tensile steel made by the technology of quench-temper hardening, makes it more durable and has extreme resistance to abrasion.
Hollow design
*We adopted the hollow design to reduce the weight to some extent.
*The surface made by the technology of chrome plating, makes it hard to rust and provides a long service life. And the surface of black-silver has a fine appearance and will give you a luxurious feel.
Suggestion:
If you want to replace a new cassette, you had better to install a suitable chain at the same time, otherwise the shifting system may cause significant noises and failures in working.
