SRAM PC870

 From SRAM:

Extremely strong. Incredibly precise. SRAM's PowerChain II increases front and load shifting performance without sacrificing rear shifting precision. The Step2™ riveting process increases the Push Pin Power for increased strength and durability.

THINGS TO REMEMBER
• An equally smooth operator on city bike paths and country trails
