    Description

    IRD Defiant Wide Compact Road Double Crankset 170mm


    We don't know whether we should call this a wide compact road, a super compact road, or a touring double. A 46-30t gives you almost as much gear range as a triple with less weight and less shifting. For most riding, you stay in the 46t and use the 30t for extended climbs.

    - 94BCD / 46-30t (yes, manufacturers still produce 94bcd rings)

    - CNC-machined 7075 aluminum rings

    - Cold forged 6061-T6 aluminum arms

    - JIS square taper

    - Suggested BB: 118mm
