A practical replacement for an e-bike owner or mechanic restoring a compatible FC-E6100, SM-CRE61 or confirmed FC-E8000 crankset.
This 170 mm left-hand crank arm unit is a straightforward replacement for compatible E6100-series e-bike cranksets. The black finish keeps the repair looking neat, while the familiar crank length restores the intended pedal position on your bike.
Its narrow, symmetrical Q-factor helps keep your feet comfortably positioned without unnecessary crowding at the pedals. The 24 mm serrated axle interface provides a secure connection, while the 3-piece construction delivers dependable stiffness for efficient power transfer under everyday e-bike loads.
Choose this component when you need a left-side replacement for an FC-E6100 or SM-CRE61 crankset, or where compatibility with an FC-E8000-related crankset has been confirmed. Check the crankset model and installation side before ordering; this is the left-hand arm only, not a complete crankset.
