|Miscellaneous||Hammerschmidt is the new Truvativ crankset that has the industry talking. It's single internal gear design offers the same range as a wide-range 2 ring crank and front derailleur, with none of the complexity. Stop missing shifts and quit wasting time cleaning a mucked-up drivetrain. It's like a double crank, front derailleur, and chain guide in one! Can only be installed on frames with ISCG or ISCG '05 chainguide tabs Can work with singlespeed, 7, 8, or 9 speed chains (match the chain type to your rear cluster) Shifts equally well under load as standing still, even while backpedaling!|
