Crank – Silver1 – low/low double steel 34×24 (with guard)

Our own design, and the crank we put on 80 percent of the Rivendells that go out of here as complete bikes. The SILVER1 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.

Crank lengths: 170mm, 173mm, 178mm, 184mm.

From 170 to 184 is only about 1/2-inch, and from 170 to 173 is, my god, only 3 mm—less than half the diameter of a standard pencil. Check out the crank length on your current bike, and if you like them, get the same length, or the closest equivalent.

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 SILVER1 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 115. The Q-Factor with a 107mm BB is 154mm.  Crank bolts included.

110/74 BCD

The chainrings are compatible with 10 speed and lower.
