We employ HollowPin™ construction on all SRAM top of the line PowerChains. HP yields plate retention strength, front and rear shifting efficiency, and low weight benchmarks unreachable in solid pin chain applications.
- PowerChain II
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.
SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains. While PL does not require special tools for install, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is good for a one-time application only.
