Prime Derailleur System Ultralight


Power Cordz brings you the lightest, strongest complete 1.2mm derailleur system on the market - Power Cordz Prime.

Now shipping in every system with our Cordz and housing are our new grommet clasps and nosed ferrules, designed for ease of installation and maximum Cord protection. 

Also our EZ bends 5mm to 4mm adapters let you install a 5mm housing into the latest shifters.

With three new colors for Prime Housing - White, Red and Black - so whatever you ride, you're sure to find a match.


Power Cordz Prime: 1.2mm Derailleur

The Derailleur Cordz System integrates perfectly with existing derailleur manufacturers (Shimano, SRAM, Campagnolo and MicroShift compatible) for road, mountain, and cyclocross bikes. We sweat the small details and include everything you need to upgrade your bicycle properly.

The Power Cordz Prime System incorporates our proven derailleur Power Cordz with our ultralight, reinforced housing (you won't find spec'd on a stock bike no matter how expensive). Included are our high-grade, alloy ferrules that resist wear.

For maximum feel, the housing is created using a unique mold to widen the inside diameter. A specially formulated liner is integrated into each section of Prime housing to protect the Cord and reduce friction.

The bottom line - The Power Cordz System is far superior to the cheap cables & housing supplied on even the most high-end of road bikes. Think weight savings, durability, and increased control. Unlike other steel cable systems, Power Cordz will not rust or corrode and do not collect dirt and grime.



Slick nylon jacket reduces friction, corrosion and fraying.

Weight: 1.5g/m - An uncut 2m derailleur cord weighs less than 3g (compared to 20g+ for a steel unit)

Diameter/Length: 1.2mm x 2.2m
