FD-M3000 FRONT DERAILLEUR

The Shimano Tiagra FC-4703 chainring will give you optimum chain engagement and smooth, precise shifting.

If you need to replace the pulley wheels for your Shimano Ultegra or Ultegra Di2 rear derailleur, this is the correct set to keep your premium drivetrain humming along with quiet, low friction precision.

With high quality bearings, a durable finish, and SHIMANO's iconic internal cam quick release, the RS400 is ready for action.

The 225mm spoke is for use on the drive side of the wheel with the chain and freewheel.
