Collection: Silver Cranks

Overall: Our own design, and the crank we put on 90 percent of the complete Rivendells. The SILVER crank is smart and exceptionally nice looking, and has the design features we sought but couldn't quite find in any other. And it passes the most rigorous testing, and is good for up to 10 speed drivetrains.

BEST MATERIALS. There are two common aluminum alloys used in cranks. The strongest and best is 7075 T6 aluminum. That's what the SILVER is made of.

 

BEST MANUFACTURING METHOD. The SILVER crank is cold-forged. It's more expensive, but imparts a grain to the metal in a way that casting and machining doesn't. But nobody really casts cranks anymore (they used to). And some really fine cranks are machined. But they're machined because forging costs too much for small operations.

It’s compatible with JIS taper bottom brackets, which are most of them, and the chainline is about 47 with a 110mm Shimano BB, and 50mm with a 113. The Q-Factor with a 107mm BB is 154mm.

On road bikes with straight (normal) chain stays, mount it on a 107-110mm square taper BB (JIS). If your bike has bowed-out chain stays like most mountain bikes, it might need a 113mm.  

On our bikes, we recommend using a 113mm BB with the Skeleton Key Front Derailer.

The chainrings are compatible with 10 speed and lower.
