SRAM's 12-speed race group has a cassette and chain that is narrower than all previous series so in order not to compromise on the strength, they have redesigned the chain and reinforced it on the upper part of the joints. This gives the flat top.

The chain is light and very quiet than before.

Made of a hard chrome alloy that gives long durability.

120 links (incl. A Flattop link to connect the chain with).

Fits Srams AXS 12-speed eTap racing group.
