Granny Gear??

[SadieKate]

That's what I've always understood, too. In which case, every bike with more than one gear has a granny.

Huh. I think if I walked into a bike shop (or talked to someone who tours with a load) and referred to a low gear of 39x23 as a granny, they'd either fall down laughing or be struck speechless.

In 25 years of pretty serious bikie-dom, I've never heard anyone call the lowest gear on a double crankset a granny.

Just my experience.
