Classic steel bikes generally featured a slick, polished silver 130 BCD double crankset. It is true most riders won't opt for the quad busting, knee destroying 53-42 gearing, but there are still good options available, and more gearing to be had at the rear wheel as well. Sugino has long been a serious player in quality aluminum cranksets for square taper bottom brackets and the RD2 Standard Crank Armscarrythe torch forward. The cleanly designed arms have the retro feel and style, but with 6061-T6 aluminum, forged and polished, performance still drives the Sugino nameplate. The premium construction process ensures a precise spider interface for proper chainring parallel alignment and overall roundness.

The square taper interface is JIS 4-taper standard, so your bottom bracket must also have the JIS taper. We highly recommend the Sugino CBB-103, just makes sure you know your frame and gearing requirements. The RD2 Crank Arms are available in several lengths, and we offer a great selection of inner and outer 130 BCD Sugino chainrings so you pair-up the ideal gearing for your needs. Others may choose the RD2 as a road single-ring crank option for most 8 or 9 speed 130 BCD rings on the market.

Ride quality, with clean design, simple graphics and gearing flexibility on your road rig with Sugino. Square taper isn't dead, it lives in thousands of daily commuting bikes. Maintain the style and tradition of the old school steel world, with the classic 130 BCD RD2 Standard Crank Arm set.
