Eclat Onyx 3pc Spline Drive Cranks

The Onyx cranks from éclat are our finest and the most inventive CrMo cranks to date. Last year they had a serious makeover in the shape of a 24mm spindle, a spline drive only version and they now use a regular 3 piece design.

The arms, still use the same invest cast boss design at the spindle and pedal ends. We have also updated the welding for improved strength; these cranks are designed to take the strain, stress and power of today’s most fierce riders.
